y+7=-2(x-3) write in slope form
Answer:
y=2x-3
Step-by-step explanation:
The slope intercept form is y=mx+b, where m is the slope and b is the y intercept.
y+7=-2(x-3) in slope formula would be y=2x-3, which also means the slope would be m=-2
I hope this helps :)

Determine the constant of variation for the direct variation given.
(0,0) ,(3,12),(9,36)
Answer:
[tex]r = 4[/tex]
Step-by-step explanation:
Given: Direct Variation
(0,0) ,(3,12),(9,36)
Required
Constant of Variation
Provided that the given data is a direct variation, the constant variation is represented by r.
r is calculated as thus;
[tex]y = rx[/tex]
Divide both sides by x
[tex]r = \frac{y}{x}[/tex]
Point (0,0) is the center of origin and cannot be used
When x = 3, y = 12
and
[tex]r = \frac{12}{3}[/tex]
[tex]r = 4[/tex]
When x = 3, y = 12
and
[tex]r = \frac{36}{9}[/tex]
[tex]r = 4[/tex]
Notice that the value of r remain constant in both cases; Hence, the constant of variation is; [tex]r = 4[/tex]
f(x)=x^2
g(x) = (x– 9)^2 +3
We can think of g as a translated (shifted) version of f.
Answer:
To get the function g, shift f up by 3 units and to the right by 9 units.
Step-by-step explanation:
The given functions are
[tex]f(x)=x^2[/tex]
[tex]g(x)=(x-9)^2+3[/tex]
If f(x) is a parent function, then g(x) can be written in the form of f(x) as
[tex]g(x)=f(x-9)+3[/tex] ...(1)
The translation is defined as
[tex]g(x)=f(x+a)2+b[/tex] ... (2)
Where, a is horizontal shift and b is vertical shift.
If a>0, then the graph shifts a units left and if a<0, then the graph shifts a units right.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
On comparing (1) and (2), we get
[tex]a=-9,b=3[/tex]
It means, to get the function g, shift f up by 3 units and to the right by 9 units.
Answer:
To get the function g, shift f up by 3 units and to the right by 9 units.

which of the following rational functions is graphed below?
Answer:
B.
Step-by-step explanation:
According to the graph the function is defined for all real number except -3 and 7 (where the two red dashed vertical lines cross the x-axis)
so our function should be :

A premier credit card has an initiation fee that provides you with the privilege to use it and a monthly fee after the first two months. The initiation fee is $62 and the monthly fee is $30 per month after the first two months. If C represents the cost and g represents the total number of months, which equation could represent this plan when you have this card for more than two months?
A. C = 30 + 62(g-2)
B. C = 30 + 62(2-g)
C. C = 62 + 30(g-2)
D. C = 62 + 30(2-g)
Answer:
The correct option is C.
Step-by-step explanation:
To have this credit card there is two fees, one that is fixed payed upfront and other that is payed after the second month. The fixed fee costs $62, and doesn't escalate with time, while the other one is $30 and starts to be charged after the second month. Therefore, the total cost of the card is the fixed fee plus the monthly fee multiplied by the number of months the user had the card subtracted by two, or as shown below:
[tex]C(g) = 62 + 30*(g-2)[/tex]
The correct option is C.

Point Z is translated right 1, down 8.
Which is the coordinate pair for the translated point Z'?
(4, –1)
(1, 4)
(1, –4)
(–8, 1)
Answer:
(1, –4)
Step-by-step explanation:
Since, Z is translated right 1 and down 8, so x- coordinate would be 1 and y-coordinate would be - 4
Hence the coordinate pair for the translated point Z' would be (1, - 4).
Please help ASAP Very easy !!!!
Answer:
C. [tex]\frac{3}{4} / \frac{1}{8}=6[/tex]
Step-by-step explanation:
This is the expression that is shown in the graph:
[tex]\frac{3}{4} / \frac{1}{8}[/tex]
We need to calculate the answer, so...
An easier way to divide a fraction by a fraction is to multiply one of the fractions with the reciprocal of the other fraction:
[tex]\frac{3}{4} *\frac{8}{1}[/tex]
8 divided by 1 is just 8 so you can simplify it:
[tex]\frac{3}{4}*8[/tex]
[tex]=\frac{8*3}{4}[/tex]
[tex]=\frac{24}{4}[/tex]
[tex]=6[/tex]
Three dressers are placed side by side one dresser is 2 feet 9 inches wide , another is 2 feet 7 inches wide , and the third 3 feet 11 inches wide . How wide are they combined
Answer:
18 feet 3 inches
Step-by-step explanation:
4 feet 7 inches + 6 feet 11 inches + 6 feet 9 inches =
10 feet 18 inches + 6 feet 9 inches =
16 feet 27 inches =18 feet 3 inches
Answer: 9.25 Feet
Step-by-step explanation:
Step 1: Take all the feet add them together = 7Ft or 84 inches
Step 2: Now add all the inches together to = 27 inches
Step 3: Add 27 + 84 = 111
Step 4: Divide that by 12 cause 1 foot = 12 inches
Step 5: should equal 9.25 :)
An employee at a factory is paid $9.25 per hour plus an $8.00 bonus for every 20 transformers assembled. Last week an employee worked 36 hours and assembled 380 transformers. How much money did the factory employee actually earn per hour last week rounded to the nearest cent?
Answer: -$13.47 per hour
Step-by-step explanation:
Hi, to answer this question we have to write an expression:
The total amount earned by the employee will be equal to the product of the number of hours he worked (36) and the amount paid per hour (9.25) ; plus the product of the amount paid for every 20 transformers assembled (8) and the number of transformers assembled (380)divided by 20 :
9.25 (36) + 8 (380/20) =
Solving:
333+ 8 (19) =
333+152 = $485
If we divide the result by the number of hours:
485 /36 = $13.47 per hour
Feel free to ask for more if needed or if you did not understand something.
Answer:
$13.47 per hour

Read the description of f below, and then use the drop-down menus to complete an explanation of why f is or is not a function.
f relates each student in Mr. Well's history class to their score on a final exam.
Answer:
Step-by-step explanation:
It is a function, since each student gets only one score one final exam,]
Domain is each student,
the first to last
Range is the score each student got:
(however the scoring was made)
f(each student) is a function because each student, or each element of the domain corresponds to the score, one and only one element of the range.
Answer:
The domain of f is 'the students in Mr. Well's history class'
The range of f is 'the final exam scores'
f 'is' a function because each student, or each element of the 'domain', corresponds to 'one' element of the 'range'
Find the area of the following shapes: c
Answer:
20
Step-by-step explanation:
First, you need to find the length of each of the bases of this trapezoid. YZ has length 5-2=3, while XW has length 8-1=7. The average of these is 5, meaning that since the height of this trapezoid is 5-1=4, the area is 4*5=20. Hope this helps!
If anybody now this pls help my homework due TOMORROW
Answer:
Part A: D. [tex]y = (x + 1)(x+3)\\[/tex]
Part B: C. [tex]3x(x-3) = 0\\[/tex]
Step-by-step explanation:
For part A) we just have to plug in 0 for x and solve for y until we find the equation that says 3 is the value for y when x is 0. For purposes of speeding up the process the correct answer is D. I will show how to check for it now.
The equation: [tex]y = (x + 1)(x+3)[/tex]
Now plug in 0 for x.
[tex]y = (0 + 1)(0+3)\\[/tex]
Now solve.
y = (1)(3)
y = 3
This proves that this is the correct answer.
For part B) we just have to plug in the give values for x separately and check for each value of x that it equals 0. For the purpose of speeding up the process the correct answer is C. I will show how to check for it now.
The equation: [tex]3x(x-3) = 0[/tex]
Now plug in x for 0 and solve:
[tex]3* 0 (0-3) = 0\\[/tex]
[tex]0(-3) = 0\\[/tex]
[tex]0 =0\\[/tex]
This equation is true, now we check for the other value of x, 3.
[tex]3*3(3-3) = 0\\[/tex]
[tex]9(0) = 0\\[/tex]
[tex]0 =0\\[/tex]
This is also true so that means this is the correct answer.

What is the value of h?
The graph shows the function f(x) = (2.5) was horizontally
translated left by a value of h to get the function g(x) = (2.5)
-2.
0
2
5
Answer:
Option (1). h = -2
Step-by-step explanation:
This question is incomplete: here is the complete question.
The graph shows the function f(x) = [tex](2.5)^{x}[/tex] was horizontally shifted by a value of h to get the function g(x) = [tex](2.5)^{x-h}[/tex]. What is the value of h ?
From the graph attached,
Point (0, 1) lies on function f(x).
If the graph of function f(x) is shifted h units left horizontally, rule for the translation will be,
f(x + h) → g(x)
For 2 units shift to the left horizontally,
f(x + 2) → g(x)
[tex](2.5)^{x+2}[/tex] = [tex](2.5)^{x-h}[/tex]
By comparing both the sides,
x + 2 = x - h
h = -2
Therefore, Option (1) will be the answer.
Answer:
A -2
