Answer:
f(-4) = - 16
Step-by-step explanation:
f(-4) = (-4)2 + 8(-4)
f(-4) = 16 + -32
f(-4) = - 16
Answer: z = -7
Step-by-step explanation:
Simplify the equation so the Integer is on the right:
8 - 12z = 92
-12z + 8 = 92
Now subtract 8 from both sides:
-12z + 8 - 8 = 92 - 8
-12z = 84
Now divide both sides by 12 to get z by itself:
-12z/-12 = 84/-12
z = -7
Answer:
$42.12
Step-by-step explanation:
35% off means she has to pay:
100 - 35 = 65% of the marked price.
65/100 × 60 = 39
Tax: 8%
8/100 × 39 = 3.12
To pay:
39 + 3.12 = 42.12
50x30=1500 (this is an approximated rounded answer)
