Answer:

Step-by-step explanation:

6x=1/2(2x +7) Multiply both sides by 2

2*6x = 1/2(2x + 7)*2

12x = 2x + 7 Subtract 2x from sides

12x-2x =2x-2x+7

10x = 7 Divide by 10

x = 7/10

x = 0.7

Let's check it

6(0.7) = 4.2

1/2 (2*0.7 + 7)

1/2 (1.4 + 7)

1/2 ( 8.4)

4.2

Both sides check. The answer must be x = 0.7

Select "Yes" or "No" to indicate whether the ordered pair is on the graph of the function f(x)=−9^x+1 .

Vinil7 [7]

I'm assuming your function is f(x) = -9^(x+1)
So we just have to plug in and see if the function is true.

1) -9^(0+1) = -9^1 = -9
YES

2) -9^(1+1) = -9^2 = -81
NO

3) -9^(-1+1) = -9^0 = -1
YES
