Answer:
$12 per hour
Step-by-step explanation:
In order to find her hourly rate we have to find the amount of dollars billed per hour. To do this we can use this expression: [tex]\frac{y2 - y1}{x2 - x1}[/tex]
Let's use the points (1, 27) and (2, 39) in the expression:
[tex]\frac{39 - 27}{2 -1}[/tex]
Now let's simplify the expression:
39 - 27 = 12
2 - 1 = 1
The expression simplifies to 12/1, or 12. This means that Brenda is billed $12 every hour she uses her phone.
I hope this helps :)

Answer:
8x(10)^9 - 2 x (10)^1
1x(10)^3 - 9 x (10)^2
Step-by-step explanation:
3.1 X (10)^4- 6.5 X (10)^2
= 31000- 650
= 30,350
For greater number
_x10^blank - _ x 10^_
8x(10)^9 - 2 x (10)^1 ( we use 9 as the power because greater number used as power gives the bigger number and the next smaller number 8 as base. Similarly we use smaller number for power to get a smaller for the greatest difference)
= 8,000,000,000 -20
= 7,999,999,980
For smaller number
_x10^blank - _ x 10^_
1x(10)^3 - 9 x (10)^2 ( we use 3 as the power because smaller number used as power gives the smaller number and the next smallest number 1 as base. Similarly we use next smaller number for power to get the next smaller for the smallest difference)
= 1000- 900
= 100
We fill in the blanks keeping in mind that we do not have to repeat the numbers from 1-9 and also the numbers should have such an arrangement that they show the smallest and largest possible differences.
what the slope of(-4,4) (-9,6)
Answer:
-2/5
Step-by-step explanation:
1. 4-6 = -2
2. -4- -9 = 5
3. -2/5
Answer:
[tex]-\frac{2}{5}[/tex]
Step-by-step explanation:
slope formula is:
[tex]y2-y1/x2-x1[/tex]
so we plug in the coordinates
[tex](6-4)/(-9--4)[/tex]
which is
[tex]2/-5[/tex]
so the slope is
[tex]-\frac{2}{5}[/tex]
Hope this helps :D Mark Brainliest please!!!
What is the equation, in slope-intercept form, for the line that passes through the point (2, −3) and is perpendicular to the line represented by y = 25x + 4 ?
Answer:
The equation is;
y = (-x-23)/25
Step-by-step explanation:
The equation of a straight line can be given as y = mx + b
where m is the slope and b is the y-intercept
for y = 25x + 4
m is 25
Now, we need the slope of a line perpendicular to this,
If two lines are perpendicular, the result of the product of their slopes is -1
m1 * m2 = -1
25 * m2 = -1
m2 = -1/25
Mathematically, we have the slope in the point slope form as ;
y+3 = -1/25 (x - 2)
y = -x/25 + 2/25
y = -x/25 + 2/25 - 3
y = -x/25 -73/25

Claire is painting some doors that are all the same size. She used 2 liters of paint to cobe 1 3/5 doors. How many liters of paint are needed for 1 door.?
Answer:
[tex]1 \dfrac{1}{4} \ liters[/tex]
Step-by-step explanation:
Given that:
Claire uses 2 liters of paint to cover 1 3/5 doors
Then in order for her to paint 1 door, She will need:
2 L = 1 3/5 door
x L = 1 door
[tex]x (L) = \dfrac{2 L \times 1 door }{ 1 \dfrac{3}{5} \ door}[/tex]
[tex]x (L) = \dfrac{2 L }{ 1 \dfrac{3}{5} }[/tex]
[tex]x (L) = \dfrac{2 L }{ \dfrac{8}{5} }[/tex]
[tex]x (L) = \dfrac{2 L\times 5 }{ 8 }[/tex]
[tex]x (L) = \dfrac{10 \ L }{ 8 }[/tex]
[tex]x(L) =1 \dfrac{1}{4} \ L[/tex]

Y intercept
End behavior
Domain
Range
Horizontal asymptote
(More than one answer)
Answer:
y-intercept,
end behavior,
range,
and horizontal asymptote
Step-by-step explanation:
I just finished the PLATO test and these are the answers
The answers are y-intercept, end behaviour, range and horizontal asymptote.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a parent function:
f(x) = eˣ
The transformed function:
g(x) = -f(x) - 4 = -eˣ - 4
g(0) = -5
f(0) = 1
From the graph, we can say the y-intercept, end behaviour, range and horizontal asymptote are different from the parent function.
Thus, the answers are y-intercept, end behaviour, range and horizontal asymptote.

7TH GRADE MATH ASAP. Liam is setting up folding chairs for a meeting. If he arranges the chairs in 8 rows of the same length, he has 11 chairs left over. If he arranges the chairs in 6 rows of that same length, he has 13 left over. How many chairs does Liam have?
Answer:
19 chairs
Step-by-step explanation:
you can make two equations
1. y = 8x + 11
2. y = 6x + 13
Y is the number of total chairs and x is the length
so 8x + 11 = 6x + 13
2x = 2
x = 1
so the length is one
To find the total number of chairs just plug in one as x
y = 8 + 11
y = 6 + 13
y = 19
so 19 chairs is the number of chairs Liam has.
PLS ANSWER
An employee's time at work increased from 32 hours per week to 40 hours per week. By what percentage did the
time at work per week increase?
Answer:
You have to take the ratio so you divide the new value on the old value and compare It with 100 so you write
(40)/(32)=(x)/(100)
And this means that x = 125
So the ratio of the increase of the new time is 125%
But the real increase is 125 - 100 = 25%

Step-by-step explanation:
Out of the 52 card deck there is a single Jack of diamonds and a single ace of clubs. Their individual probabilities are therefore both 1/52.
For the probability that you can pick either of those card you have to add up their probabilities;
= 1/52 + 1/52
= 2/52
= 1/26

Write an equation in point-slope form for the line through the given point with the given slope.(3,-4);m=-1/4
Answer:
The equation in point-slope form for the line through the given point with the given slope is: [tex]y+3 = -\frac{1}{4}(x-3)[/tex]
Step-by-step explanation:
The point slope form of a line is given by:
[tex]y-y_1 = m(x-x_1)[/tex]
Here m is the slope and (x1,y1) are the coordinates of the point through which the line passes.
Given
m = -1/4 and
(x1,y1) = (3,-4)
Putting the values in the point-slope form of line
[tex]y-(-4) = -\frac{1}{4}(x-3)\\y+4 = -\frac{1}{4}(x-3)[/tex]
Hence,
The equation in point-slope form for the line through the given point with the given slope is: [tex]y+3 = -\frac{1}{4}(x-3)[/tex]
Carlos says that if the numerators of two fractions are the same, you can compare the denominators to determine which
one is greater. Which statement best describes Carlos's idea?
Carlos is correct. If the numerators are the same, the fraction with the lesser denominator will be greater.
Carlos is correct. If the numerators are the same, the fraction with the greater denominator will be greater.
Carlos is incorrect. If the numerators are the same, the fractions will be equal.
Carlos is incorrect. You cannot compare fractions using only the denominators even if the numerators are equal.
Answer:
Carlos is correct. If the numerators are the same, the fraction with the lesser denominator will be greater.
Step-by-step explanation:
I'll answer this question using the following illustration.
Let a fraction be:
[tex]\frac{1}{2}[/tex]
and another fraction
[tex]\frac{1}{4}[/tex]
Both numerators are 1. In other words, they are equal
When you compare the denominator, 2 and 4, the fraction with lesser denominator is greater
This is so because:
[tex]\frac{1}{2} = 0.5[/tex]
[tex]\frac{1}{4} = 0.25[/tex]
By comparison
[tex]0.5 > 0.25[/tex]
This analysis can be used for any fraction as long as they have the same numerator
Hence, option A answers the question
Answer:
A

Eddie found a store that sells cell phone cases for $18.50 plus $0.15 per letter engraved on the case. A second store sells cases for $18.00 plus $0.25 per letter engraved on the case. How many letters would Eddie have to engrave on his case for it to cost the same at either store?
Answer:
5 letters
Step-by-step explanation:
Let x = the number of letters engraved.
For the first store, the cost can be written as (18.50 + 0.15x).
For the second store, the cost can be written as (18 + 0.25x).
For the cost and value of x to be the same, let them equal eachother and evaluate x:
18.5 + 0.15x = 18 + 0.25
0.1x = 0.5
∴x=5

A card is drawn from a standard deck of 52 cards. What is the probability this card will be a king or an ace?
A. about 3.9%
B. about 7.7%
C. about 15.4%
D. about 50%
Answer:
C. about 15.4%
Step-by-step explanation:
There are 52 cards in a deck
There are 4 kings and 4 aces
so, 8/52 is the chance of getting either of those two.
8/52 is about 0.1538 or 15.38%
15.38% rounded would be 15.4%

The vertical asymptotes of the given function are x = 1 and x = -1,
We have given the rational function is 10/(x²-1).
We need to find the vertical asymptotes of this function.
Since Vertical asymptotes occur when the denominator of the function becomes zero and the numerator is not zero.
To determine the vertical asymptotes of the function, we need to solve the denominator for x²-1=0.
x²-1=0
x²=1
x=±√1
x=±1
Therefore, the vertical asymptotes of the given function are x = 1 and x = -1, since the denominator becomes zero at x=1 and x=-1.
