Answer:
x = 8
Step-by-step explanation:
if f(x) = -17
then we can type:
- 3 x + 7 = -17
solving for "x", subtract 7 from both sides
- 3 x = - 17 - 7
- 3 x = - 24
divide both sides by -3 to isolate "x"
x = -24 / (-3)
x = 8

Area of a circle is pi x r ^2
R = diameter/2

Area = 3.142 x 0.9^2
Area = 2.5 square cm.

$68 - 59.9 = $8.1
$8.1/$68 = 0.11911764705
0.11911764705 x100 = 11.911764705
11.911764705 is rounded up to 12
