Step-by-step explanation:
so,
y = -9x + 2
now we need to transform this equation that actually x is calculated out of y.
and then, at the end, to make the inverse function a formally correct function, we rename x to y and y to x.
so,
y = -9x + 2
y - 2 = -9x
x = -(y - 2)/9 = (-y + 2)/9
=> for a formal function definition
y = (-x + 2)/9

Tianna works at a call center. Between 12 PM and 4 PM only 5% of her attempted calls pick up. Between 4 PM and 8PM, 15% of her attempted calls pick up. If she expects to make 80 calls between 12 PM and 4PM and 120 calls between 4 PM and 8 PM, how many total pick ups can she expect during her entire shift?
15
18
4
22
Answer:
.05(80) + .15(120)=
4 + 18 = 22
So, the total pick ups is 22.

Answer:
A) 5; B) 32; C) 3; D) 14; E) 1/3
Step-by-step explanation:
Answer:
1. 5
2. 42
3. 3
4. 14
5. 0.3333
Step-by-step explanation:
Third Grade:
8 x 5 = 40
8 + 42 = 40
21 ÷ 7 = 3
21 - 14 = 7
---------------------------21 • x = 7
Which can be written as:
21x = 7
To solve the equation above, we need to remove the 21 on the left side to make the x alone. To do that, we divide both sides by 21.
21x/21 = 7/21
21x/21 is x and 7/21 is 0.3333 which means our equation will look like this:
x = 0.3333
Thus, the answer to "21 times what equals 7?" is 0.3333.

21. You place a mat around a 25 in by 21 inch painting as shown. The mat
is twice as wide at the left and right of the painting as it is at the top an
bottom of the painting. The area of the mat is 714 square iinches (note:
the area of the border). How wide is the mat at the left and right of the
painting? At the top and bottom of the painting? (P.264 #66)
Using a quadratic equation according to the area of the rectangular mat, it is found that:
At the top and bottom of the painting, the width is 0.654 inches.At the left and right of the painting, the width is of 1.308 inches.The area of a rectangle of length l and width w is given by:
[tex]A = lw[/tex]
In this problem:
The length of the figure is of [tex]l = 25 + 4x[/tex].The width of the figure is of [tex]w = 21 + 2x[/tex].Area of 714 square inches, thus:[tex]lw = 714[/tex]
[tex](25 + 4x)(21 + 2x) = 714[/tex]
[tex]8x^2 + 134x + 525 = 714[/tex]
[tex]8x^2 + 134x - 189 = 0[/tex]
Which is a quadratic equation with [tex]a = 8, b = 134, c = -189[/tex].
The, to find the widths of the mat, we have to first find the value of x, solving the quadratic equation.
[tex]\Delta = 134^2 - 4(8)(-189) = 24004 [/tex]
[tex]x_{1} = \frac{-134 + \sqrt{24004}}{2(8)} = 0.654[/tex]
[tex]x_{2} = \frac{-134 - \sqrt{24004}}{2(8)} = -9.03[/tex]
We are interest in the positive value of x, so x = 0.654.
At the top and bottom of the painting, the width is of 0.654 inches.[tex]2(0.654) = 1.308[/tex]
At the left and right of the painting, the width is of 1.308 inches.A similar problem is given at https://brainly.com/question/14099239

Sam bowled three games with scores of 210, 185, and 190. He needs to have a four-game average of 205 to qualify for an elite bowling league. What score does he have to bowl on the fourth game to have the average of 205 that he needs?
Answer: 235
Step-by-step explanation:
Total score if he average 205 = 205 * 4 = 820
Score needed on 4th game = 820 - 210 -185 - 190 = 235

What is the width of a rectangular prism with a length of 24 inches and height of 10 inches and a volume of 2880 cubic inches?
Answer:
12
Step-by-step explanation:
you reverse the operations, you multiply LxWxH to get the volume, so you can do V/L/H to get the width. 2880 divided by 24 equals 120, and 120 divided by 10 equals 12, so therefore the width is 12. Hope this helps!
