Answer:
your slope would be 5/4
Step-by-step explanation:
your x will always be your slope. when you rewrite the equation it would be
y=5/4x-7
so from -7 you would go up 5 and over 4.
Again your x value will always be your slope.

Step-by-step explanation:
Si se oferta un producto al 10% de descuento, esto significa que el precio final del producto será 90% del precio original. Para hallar estos datos, debemos usar una regla de tres, de la siguiente forma:
100% 90%
-------------------- → ---------------------------
Precio Original Precio con Descuento?
SARAPES
- Ana: descuento (14), precio rebajado 126
Precio rebajado = 140.90 / 100 = 126
Descuento: 140 - 126 = 14
- Javier: descuento (8), precio rebajado 72
Precio rebajado = 80.90 / 100 = 72
Descuento: 80 - 72 = 8
ARETES
- Luis: descuento (5), precio rebajado 72
Precio rebajado = 50.90 / 100 = 45
Descuento: 50 - 45 = 5
- Ana: Precio original (60) , descuento (6), precio rebajado 54
Precio original: X.0,10 = 6
X = 60
Precio rebajado: 60 - 6 = 54
- Javier: Precio original (40) , descuento (4), precio rebajado 36
Precio original: X.0,10 = 4
X = 40
Precio rebajado: 40 - 4 = 36

The LA Dogers hit the most home runs in 2014. The number of home runs accounted for 6% of the entire major league Baseball home run count.If 583 total home runs were hit, then how many did the LA Dogers hit
Given:
Total number of home runs = 583
Home runs hit by LA Dogerse = 6% of the total home runs
To find:
The number of home runs hit by LA Dogers.
Solution:
We have,
Home runs hit by LA Dogerse = 6% of the total home runs
[tex]=\dfrac{6}{100}\times 583[/tex]
[tex]=\dfrac{3498}{100}[/tex]
[tex]=34.98[/tex]
[tex]\approx 35[/tex]
Therefore, LA Dogerse hits about 35 home runs.

What is the formula of area of a quadrant?
Answer:
that is, pi (π) multiplied by the radius squared (r2). Now, to calculate the area of a quadrant, divide the area of a circle by 4 (as four quadrants make a circle). We get, Area of a quadrant, A= (πr2)/4 Square units.
Write an equation of the line passing through the point (2,8) that is perpendicular to the line 2x-3y=7
Answer:
y = (-3/2x) + (35/4)
Step-by-step explanation:
So the perpendicular line will have a slope that is the opposite reciprocal of the other line's slope. Solve for the original line's slope first:
2x - 3y = 7 --> -3y = -2x + 7 --> y = (2x/3) - (7/3)
So, the slope of the perpendicular line will be (-3/2x)
Solve for the y-intercept of the perpendicular like by using the linear equation and substituting in (2,8):
8 = (-3/(2*2)) + b --> (32/4) = -(3/4) + b --> b = (35/4)
So, y = (-3/2x) + (35/4)

9 t-shirts and a hat costs £93.00
4 t-shirts and a hat costs £43.00.
How much does a t-shirt cost?
How much does a hat cost?
Answer:
A t-shirt costs 10.00 pounds and a hat costs 3.00 pounds.
Step-by-step explanation:
x is a t-shirt
y is a hat
9x + y = 93.00
4x + y = 43.00
(9x + y) - (4x + y) = 93.00 - 43.00
9x + y - 4x - y = 50.00
5x = 50.00
x = 50.00/5
x = 10.00 [a t-shirt costs 10.00]
4x + y = 43.00
4×10.00 + y = 43.00
40.00 + y = 43.00
y = 43.00 - 40.00
y = 3.00 [a hat costs 3.00]
An experimenter studies vision in low light by
having participants sit in a darkened room for
either 5, 15, or 25 minutes and then testing their
ability to correctly identify 20 objects. (a) What is
the independent variable here? (b) What are the
conditions? (c) What is the dependent variable?
(d) You would use the scores from which variable
to create a frequency distribution?
Answer:
Independent variable- time spent in the dark room
Dependent variable - number of objects correctly identified
Conditions of the experiment- low light environment and lighted environments
Scores from the independent variable are used to construct the frequency distribution
Step-by-step explanation:
The independent variable is the factor that is being manipulated in an experiment and this time it is the time spent in a darkened room.
The dependent variable is the response variable, in this case, the number of objects correctly identified.
The experimental conditions involved bringing people from a lighted area into a darkened room.

Describe the transformation of each function compared to its parent function.
I need help please!
Step-by-step explanation:
In general, for all problems like this, remember the acronym VOHI:
vertical outside, horizontal inside.
1. The parent function here would be [tex]f(x)=x^{2}[/tex]. 4 has been subtracted from the inside, so it is a horizontal change. You might think that it is moving left 4, but it's actually moving right 4. There is a reason for this, but it's not necessary for you to know right now. All you need to remember is that when inside the parentheses, minus means moving right, and plus means moving left. You also have a 9 added to the outside. Vertical outside. This is a vertical change, meaning up and down. This function has been moved right 4 and up 9.
2. First, the parent function is again [tex]f(x)=x^{2}[/tex]. This time, we have [tex]\frac{1}{4}[/tex] on the outside of our function. This means it is a vertical transformation. When the value on the outside is > 1, it is a vertical stretch. When the value is between 0 and 1 (0<a<1), it is a vertical shrink. [tex]\frac{1}{4}[/tex] is between 0 and 1. So, this is a vertical shrink by a factor of [tex]\frac{1}{4}[/tex]. Next, there is a 6 on the inside of the parentheses, meaning a horizontal translation. Remember from problem 1, though, minus=right and plus=left. So, this function has been vertically shrunk by [tex]\frac{1}{4}[/tex] and moved left 6.
3. Again, parent function: [tex]f(x)=x^{2}[/tex]. This one just has [tex]\frac{3}{2}[/tex] on the outside. We know that it's on the outside because otherwise there would be parentheses around both [tex]\frac{3}{2}[/tex] and x. There is not, so it is outside. Outside, vertical. This is a vertical change. Looking back at problem two, when a value is >1, which this is, it is a vertical stretch. So this function has a vertical stretch by [tex]\frac{3}{2}[/tex].
I hope this helps!
Transformation involves changing the position and/or size of a function.
The transformations are:
Translate f(x), 4 units right, and 9 units up.Translate f(x), 4 units left, then compress f(x) vertically by 1/4Vertically stretch f(x) by 3/2[tex]\mathbf{1.\ f(x) = (x - 4)^2 +9}[/tex]
The above function is a square function, and the parent function is:
[tex]\mathbf{f(x) = x^2}[/tex]
First, the function is translated right by 4 units (this is represented by subtracting 4 from x.
i.e.
[tex]\mathbf{f(x) = (x - 4)^2}[/tex]
Next, the function is translated up by 9 units (this is represented by adding 9 to the value of y.
i.e.
[tex]\mathbf{f(x) = (x - 4)^2 + 9}[/tex]
So, the transformation from the parent function is: Translate f(x), 4 units right, and 9 units up.
[tex]\mathbf{2.\ f(x) = \frac 14(x + 4)^2}[/tex]
The above function is a square function, and the parent function is:
[tex]\mathbf{f(x) = x^2}[/tex]
First, the function is translated left by 4 units (this is represented by adding 4 from x.
i.e.
[tex]\mathbf{f(x) = (x + 4)^2}[/tex]
Next, the function is vertically compressed a factor of 1/4 (this is represented by multiplying the function by 1/4
i.e.
[tex]\mathbf{f(x) = \frac 14(x + 4)^2}[/tex]
So, the transformation from the parent function is: Translate f(x), 4 units left, then compress f(x) vertically by 1/4
[tex]\mathbf{3.\ f(x) = \frac 32x^2}[/tex]
The above function is a square function, and the parent function is:
[tex]\mathbf{f(x) = x^2}[/tex]
The function is vertically stretched a factor of 3/2 (this is represented by multiplying the function by 3/2
i.e.
[tex]\mathbf{f(x) = \frac 34 \times x^2}\\[/tex]
[tex]\mathbf{f(x) = \frac 34 \timex x^2}[/tex]
So, the transformation from the parent function is: Vertically stretch f(x) by 3/2

Round each of these numbers to the degree of accuracy shown in the brackets
a) 4865
(Nearest ten)
Answer:
irst, 4865 rounded to the nearest ten is:
4870
Step-by-step explanation:
Here we will tell you what 4865 is rounded to the nearest ten and also show you what rules we used to get to the answer.
Remember, we did not necessarily round up or down, but to the ten that is nearest to 4865.
When rounding to the nearest ten, like we did with 4865 above, we use the following rules:
A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.

is this correct? ILL MARK YOU BRAINIEST
Answer:
yes
Step-by-step explanation:
This is correct.
Since every operation in this is multiplication, you can remove the parentheses. This is the associative property of multiplication. Now you can group the exponents and the normal factors together.

(9x – 8) cm
Part A - If AB is 128 centimeters long, what is the value of a?
Part B - What is the length of AM?
AM
cm.
Part C - What is the length of BM?
BM
cm.
Part D - Is point M the midpoint of AB? Justify your answer.
Answer:
Part A
x = 8
Part B
AM = 64 cm
Part C
BM = 64 cm
Part D
AB = AM + BM
Step-by-step explanation:
Consider the line segment below.
АM = (7x + 8) cm
BM = (9x – 8) cm
Part A - If AB is 128 centimeters long, what is the value of x?
AB = AM + BM
128 = (7x + 8) + (9x - 8)
128 = 7x + 9x + 8 - 8
128 = 16x
x = 128/16
x = 8
Part B - What is the length of AM?
АM = (7x + 8) cm
AM = 7(8) + 8 cm
AM = 56 + 8 cm
AM = 64 cm.
Part C - What is the length of BM?
BM = (9x – 8) cm
BM = 9 × 8 - 8 cm
BM = 72 - 8 cm
BM = 64 cm.
Part D - Is point M the midpoint of AB? Justify your answer.
A.............. M............... B
Hence: From the Above illustration,
M is the Midpoint because it divided AB into 2 equal parts
= AM and BM
Hence:
AB = AM + BM
