<span>(2) y is the total cost, x is the number of months of service, $40 is the installation fee, and $90 is the service charge per month.</span>
y = 40 + 90x
y = total cost
x = number of months of service
40 = one time installation fee
90 = monthly service charge.
Let us assume that the number of months of service is 10 months. then, the total cost would be:
y = 40 + 90(10)
y = 40 + 900
y = 940
Answer:
For number 1: y=2 and x=3
Consider a right triangle in which one of the angles 
satisfies
That is, the side opposite occurs in a ratio of 3 to 5 with the hypotenuse. The side adjacent to then occurs in a ratio of 4 to 5 with the hypotenuse. In other words,
because
Then in this triangle,
Answer:
x = -5
Step-by-step explanation:
- Subtract 3 from each side, so it now looks like this: 2x = -10
- Divide each side by 2 to cancel out the 2 next to x. It should now look like this: x = -5
I hope this helps!
