Answer:

Domain: -1 ≤ x ≤ 4

Range: -20 ≤ 5f(2x) ≤ 30

Step-by-step explanation:

Inputs of f are between -2 and 8

Input is now 2x, so

-2 ≤ 2x ≤ 8

-1 ≤ x ≤ 4

(Horizontal stretch, factor 1/2)

Range of f is -4 ≤ y ≤ 6

So,

-20 ≤ 5y ≤ 30

(Vertical stretch, factor 5)

16. Find the value of y. ​
devlian [24]

y + (2x -12) = 180 (since they are supplementary angles)

(2x-12) = 96 ( since they are alternate exterior angle)

2x = 96 + 12

2x = 108

x = 108/2

x = 54.

y+( 2x-12)=180

y+(2× 54 -12) = 180

y + (108-12) = 180

y + 96 = 180

y= 180-96

y = 84.

Write a quadratic equations given the roots 5/2 and 9
sukhopar [10]

Answer:

(x-5/2)(x-9).

x^2-5/2x-5/2x+45/2.

Multiply the number by 2.

which is 2(x^2-5/2x-5/2x+45/2).

2x^2-5x-5x+45.

2x^2-10x+45.

Tim earned $300 in five days. After the first day, he earned $10 more each day than the day before. How much did Tim earn on the
Vika [28.1K]
Use the equation 300⇒5x to find how much tim made each day on average. 
x⇒60   so, Day 1: $60, Day 2: $70 etc.. so the equation 300=5x+10 suffices the problem. 300⇒5x+10 ⇒    290=5x
x=58
So, Tim earned $58 his first day. Hope this helped.

-6+x/x^4 limit at x →0
Jlenok [28]

Answer:

not existing

Step-by-step explanation:

\frac{ - 6 + x}{ {x}^{4} }

lim x goes to 0 is

\frac{ - 6 + 0}{ {0}^{4} }  =   \frac{ - 6}{0}

so not exist

I'm not sure if u mean that or this

\frac{2 |x - 3| }{5}  = 6 \\

5 \times  \frac{2 |x - 3| }{5}  = 5 \times 6 \\

2 |x - 3|  = 30

\frac{2 |x - 3| }{2}  =  \frac{30}{2}  \\

|x - 3|  = 15

x - 3 = 15

x - 3 + 3 = 15 + 3

x = 18

<h2>OR</h2>

x - 3 =  - 15

x - 3 + 3 =  - 15 + 3

x =  - 12
