Answer:
Thr answer will be -9
Divide each term by -7 and simplify
No they don't. 2/3=.67, 3/4=.75. 8-.75=7.25. 7.25/.67=10.82.... 87/8=10.88 :) hope this helps
Answer:
5 hours
Step-by-step explanation:
First subtract the food cost from the total bill.
351.20 - 200.60 = 150.6
Than divide 150.6 by 30.12
150.6 ÷ 30.12 = 5
Answer:
x = 10; y = 20
Step-by-step explanation:
y = 2x
y = x +10
Substitute y of the second equation with 2x.
2x = x + 10
x = 10
y = 2x = 2(10)
y = 20
Answer: x = 10; y = 20
Answer:
The slope = 22.
Step-by-step explanation:
First we find the derivative:
y' = 6x^2 - 2
This gives the slope of the line tangent to the point (x, y) on the graph of y.
So for the tangent at (-2, 45) the slope is:
6(-2)^2 - 2 = 24 - 2
= 22.
