Answer:
x = 27
Step-by-step explanation:
Supplementary angles add up to 180 degrees
65 + 5x - 20 = 180
45 +5x = 180
5x = 135
x = 27
Answer:
The range is { -1,3,7,11,15}
Step-by-step explanation:
The range is just the output values
f(-2) = 4(-2) +7 = -8+7 =-1
f(-1) = 4(-1) +7 = -4+7 = 3
f(0)= 4(0) +7 = 7
f(1) = 4(1) + 7 = 11
f(2) = 4(2) +7 = 8+7 = 15
Answer:
Alex will pay $3,662
Step-by-step explanation:
To find the total cost, we can make an equation modeling y=mx+b, with y being the total cost, m being the monthly charges, x being the amount of time it takes, and b being the 10% down payment.
After plugging in the numbers to the equation, we get y=276(12)+350.
Now all that is left is to solve the equation as follows:
y=3,312+350
y=3,662
Answer:
x < 12
Step-by-step explanation:
150 - 20 = 130
x < 130 / 10 - 1
x < 13 - 1
x < 12
