Answer: -4
Step-by-step explanation:reverse the steps
3(x-7)= -9
3(x-7)/3= -9/3
x-7= -3
x= -3+7
x= -4
Answer:
All in the explanation.
Step-by-step explanation:
Since we will only be renting the car for one day it will only be a $50 dollar base fee. If we drive 192 miles and just rent it for one day the equation modeled will be $0.18(192) + 50 = 34.56 + 50 = $84.56 total.
14 to the second power hope this helps have a nice day
Answer:
18. Slope (m) = 1/2
Y-intercept (b) = -6
19. Slope (m) = 2
Y-intercep (b) = 8
20. y = 1/2 + 6
Step-by-step explanation:
y = mx + b
y - 2x = 8
y = 2x + 8
The diagonal of square is a√2
the half of it a√2/2=12
a=12*2/√2=12√2
S=a^2=12√2*12√2=288
