Answer:
First step: Combine like terms, Answer: [tex]x=15[/tex]
Step-by-step explanation:
First, we need the variable on the left side and constants on the right.
So, we combine like terms to get [tex]3x=36+9=45[/tex].
Then, we can divide both sides by [tex]3[/tex] to isolate the variable and get [tex]\boxed{x=15}[/tex].
Write the slope-intercept equation of the line with slope -3/4 passing through the point (-4,5). If necessary, answer using fractions, not decimals.
Answer:
Answer:
y = -3/4x + 2
Step-by-step explanation:
y = -3/4x + b
5 = -3/4(-4) + b
5 = 3 + b
2 = b
Graph thee line that represents this equation:
y+2=1/2(x+2)
Answer:
[tex]y = \frac{1}{2} x - 1[/tex]
Explanation:
The first pic shows the line graphed, while the second pic shows how to turn the equation into proper slope-intercept form.
The only steps the second pic is missing however, is flipping the sides around to be better understood (optional), and more importantly subtracting 2 on both sides in order to move it to the other side, to get 2y = x - 2. And dividing the 2 on both sides to get y by its self, to get:
y = (x-2)/2 , or y = 1/2 x - 2/2 , which if you notice 2/2 makes it equal to one whole so your answer is y = 1/2 x - 1 .

Answer:
angles 2 and 10 are corresponding Angles while angles 6 and 11 are alternate Angles
Answer:
1. False Same side exterior angles refers to same side transversal An example; opposite ends both same side of transversal. see 2nd attachment.
2. False interior alternate are both interior alternate on a Z 3 would be alternate with 6 as both are within the z and diagonally opposite at ends of the z shape.
3. True (yes both same sides of transversal one is left of parallel line the other is left of the next parallel.
4. False ( 12 is only alternate with 1 as alternate is within the z shape as exterior and opposite sides of the transversal)
Step-by-step explanation:
Alternate Interior Angles – Alternate interior angles are the pair of angles on the inner side of the two parallel lines but on the opposite side of the transversal. Alternate Exterior Angles – Alternate exterior angles are the pair of angles on the outer side of the two parallel lines but on the opposite side of the transversal
Same side exterior angles - are seen on the blue spots on the 2nd diagram transversal
HELPPPPPPPPPPP. please explain how u got the answer
Step-by-step explanation:
the key is x = 0.
also I see in the first table no "run-away" effect of some values, so my first suspicion is : it is linear.
let's test it.
a linear function is a line :
y = ax + b
remember, x = 0 is a key element.
y = a×0 + b
-3 = a×0 + b
-3 = b
so, we know, the line function is
y = ax - 3
now, for the a. let's use the next xy pair (1, 1).
1 = a×1 - 3
4 = a
aha ! our line function is therefore
y = 4x - 3
verify with the next 2 points (2, 5) and (3, 9)
5 = 4×2 - 3 = 5 correct
9 = 4×3 - 3 = 9 correct
linear type and equation confirmed.
the second table :
yes, we see relatively big y values compared to the x values.
and the y values follow the powers of 2
so it seems to to be exponential.
64 = 2⁶
32 = 2⁵
16 = 2⁴
8 = 2³
so, while x increases, the powers of 2 decrease. so, we must build something like y = 2^x, but it must run contrary to the increase in x.
the old trick : c-x.
again, x= 0 is key. when x = 0 we get the biggest y (64). that means that gives us c.
64 = 2^(c-x) = 2^(c-0) = 2^c = 2⁶
=> c = 6
so, we suspect the exponential function
y = 2^(6-x)
let's verify with the other points
(1, 32)
32 = 2^(6-1) = 2^(5) = 32 correct
(2, 16)
16 = 2^(6-2) = 2^(4) = 16 correct
(3, 8)
8 = 2^(6-3) = 2^(3) = 8 correct
so, yes, it is the exponential function
y = 2^(6-x)
Simplify the equation (3x³)⁴.....
....................
Answer:
(3x)¹²
Step-by-step explanation:
(3x³)⁴ is in form of (e³)⁴ which can be written as e³×⁴
= e¹²
so (3x³)⁴ can be written as (3x)¹²
Answer:
3x¹²
Step-by-step explanation:
According to the power rule of exponents, to simplify a power of a power, you multiply the exponents and keep the base the same. In this case, 3 and 4 are the exponents. 3 times 4 is 12. So the answer would be 3x to the power of 12.

hope this helps
Answer:
-12
Step-by-step explanation:
-3 + -9
turns into
-3 - 9
Which means on the number line, we start at -3 and move to the left 9 units.
When we move to left on the number line by 9, we are at -12.
Which means -3 - 9 (-3 + -9) = -12

Answer:
81.75
Step-by-step explanation:
First, find the median of all the answers.
78.25, 77.75, and 84 = 80 (median)
now that we know 80 is the median, we will add it to our solution.
And still, there is no OTHER TEST in to make this stay 80.
78.25, 77.75, 84, and 80 = 79.125
since this is incorrect, we go higher.
78.25, 77.75, 84 and 81 = 79.625
since this is also incorrect, we go higher.
78.25, 77.75, 84 and 82 = 80.125
since this is higher and incorrect, we will go lower to 81.5.
78.25, 77.75, 84 and 81.5 = 79.875
since this is lower AND 82 is not the correct solution, we will go up by 0.25.
78.25, 77.75, 84 and 81.75 = 80
To check, we will do the problem again.
78.25, 77.75, 84 and 81.75 = 80
So, the solution is 81.75

If y varies directly as x and y = 3 when x = 10, find x when y = 8.
Answer:
x=26.6 when y=8
Step-by-step explanation:
y=Kx, k=y/x, when y is 3 and x is 10,
k=3/10= 0.3
but when y is 8, x will be given by
x=y/k
x=8/0.3
x=26.6 approximately 27

The bag of dog food would last for 21 days.
The bag contains 42 cups of dog food. If the dog eats [tex]2\frac{1}{3}[/tex] cups everyday, the amount of cup in the bag decreases by [tex]2\frac{1}{3}[/tex] cups everyday. This can be represented with this expression: 42 - [tex]2\frac{1}{3}[/tex]d. Where d represents the number of days.
In order to determine the number of days in which the bag would be emptied, this equation can be used:
Number of days the dog food would last = number of cups in the cup / amount the dog eats each day
42 ÷ [tex]2\frac{1}{3}[/tex]
42 ÷ [tex]\frac{7}{3}[/tex]
42 x [tex]\frac{3}{7}[/tex] = 21 days

You and your mom enter a drawing with 3 different prizes. A total of 10
people entered the drawing, and prizes are awarded randomly.
There are 720 ways to award the prizes.
What is the probability that you win
prize?
first prize and your mom wins second
Answer:
Step-by-step explanation:
Number of people who entered the drawing = 10
Number of prizes = 3
Number of ways to award the prize = 720 ways
The total number of ways that 3 prizes can be awarded to the 10 people can be determined as:
10*9*8 = 720
The total number of ways in which I win the first prize and my mom wins the second prize would be 1*1*8 = 8
Thus the probability that I win the first prize and my mom wins the second prize would be 8/720
