Answer:

g(2)=2

Step-by-step explanation:

g(x)=x2-x

<h3>Answer: 2</h3>

Work Shown:

g(x) = x^2 - x

g(2) = 2^2 - 2 ... replace every x with 2

g(2) = 4 - 2

g(2) = 2

In this case, we won't use f(x)

Two mechanics worked on a car. the first mechanic worked for 10 hours, and the second mechanic worked for 15 hours. together the

Yuliya22 [10]

Let x and y be the rate per hour for Mechanic 1 and 2 respectively.

Then,
x+y=205 ---------- (1)
Additionally,
10x+15y = 2500 ------ (2)

Solving equations 1 and 2;
Multiply (1) by 10 and subtract two from the result,
10x+10y = 2050
10x +15 y =2500
----------------------
-5 y = --450 => y = 450/5 = $90
Then,
x= 205-90 = $115

Therefore,
Mechanic 1 charged $115 per hour
Mechanic 2 charged $90 per hour

What 2 numbers can I add to the table to still have a function x: 6,3,9,7 y: 6,8,12,8 numbers I can use are: 3,6,7,8,9,12

Answer:

8, 12

Step-by-step explanation:

The x-values of a function cannot repeat. That is, the x-values already in the table, {3, 6, 7, 9}, cannot be used again. Any added x-values must be different from these if your relation is to remain a function.

Of the choices offered, only 8 and 12 can be used for added x-values.

grin007 [14]

5w + 9z = 2z + 3w

2w + 9z = 2z

2w = -7z

w= -7/2z or w= -3.5z
