It’s 15.5 because they’re asking on average per hour so to find the average add 10+21=31 and then divide by 2 (the number of jobs and the two separate wages) and you get $15.5

Which function represents the graph of f(x)=−4|x| after it is translated 3 units down?
vladimir1956 [14]

Answer:

The function with blue line (see attachment) represents the graph of f(x) = -4\cdot |x| after it is translated 3 units down.

Step-by-step explanation:

Mathematically speaking, a translation in the y-direction is defined by the following expression:

g(x) = f(x) + k (1)

Where:

g(x) - Resulting function.

f(x) - Original function.

k - Translation factor (k > 0 - Translation in the +y direction/k< 0 - Translation in the -y direction).

If we know that original function is translated 3 units down and f(x) = -4\cdot |x|, then the resulting function is:

g(x) = -4\cdot |x|-3

Lastly, we graph both original and resulting functions with the help of a graphing tool, whose outcome is presented in the image attached below:

Please notice that the red line represents the original function, whereas the blue line represents the resulting function.

(x-5)(X+12)=-70<br><img src="https://tex.z-dn.net/?f=%28x%20-%205%29%28x%20%2B%2012%29%20%3D%20%20-%2070" id="TexFormula1" title
madreJ [45]

Answer:

x =  - 2

x =  - 5

Step-by-step explanation:

Give

(x - 5)(x + 12)

Apply FOIL Method

x {}^{2}  + 7x - 60 =  - 70

Add 70 on both sides

{x}^{2}  + 7x + 10

Factor

(x + 2)(x + 5)

So our roots are

x=-2

x=-5
