Hello :
let : $y= \frac{3x-7}{x+1}$
calculate : x ......x ≠ -1
 $y(x+1) = 3x-7$
$yx+y =3x-7$
$yx-3x = -y-7$
$x(y-3) = -7-y$
$x = \frac{y+7}{3-y}$
the inverse function is : $g(x) = \frac{x+7}{3-x}$
domain of : g is the range of : f
as an interval : ]-∞: 3 [U ]3;+∞[

I don't know how to do this please help

5z>15-----subtract 2 on both sides
z>3----divide by 5
therefore, z must equal -10, or -4

Look at the number in the place-value table. The value of the 8 in the hundreds

Artyom0805 [142]

Answer:

10 times the value

Step-by-step explanation:

The value of 8 in the hundreds place (800) is 10 times the value of 8 in the tens place (80).

I figured this out by dividing 800 by 80 = 10.

2x + 1 = -13

2x = -13 -1

2x = -14

x = -14 / 2

x = -7
