The answer is 5
Step-by-step explanation:
I took the test :)
-7x + y = -6 |add 7x to both sides
y = 7x - 6
the slope: m = 7
the y-intercept: y = -6
Answer:
h(-8) = -40
Step-by-step explanation:
Find h(-8) by plugging in -8 as x:
h(x) = 1/4x² + 7x
h(-8) = 1/4(-8)² + 7(-8)
Simplify:
h(-8) = 1/4(64) - 56
h(-8) = 16 - 56
h(-8) = -40
So, the answer is h(-8) = -40
Answer:
Phoebe: 180
Andy: 60
Polly: 30
Step-by-step explanation:
Let Polly's money be P
Then Andy's money = P * 2 = 2P
Then Pheobe's money = 2P * 3 = 6P
There are 9 P's (P + 2P + 6P)
270 / 9 P's = 30
Therefore P = 30
Polly gets $30
Andy gets 30 * 2 = $60
Phoebe gets 60 * 3 = $180
Checking:
180 + 60 + 30 = 270
