You are given two equations, solve for one variable in one of the equations. Say you solved for x in the second equation. Then, plug in that value of x in the x of the first equation. Solve this (first) equation for y (as it should become apparent) and you'll get a number value. Plug in this numerical value of y into the y of the second equation. Solve for x in the second equation. And there you have it: (x, y)
Answer:
f(x)=−5x−20
Step-by-step explanation:
It's decreasing 5 degrees every hour, which is represented by -5x
You also have to take away the 20 (-20) from where it started.
So, f(x)=−5x−20
Answer:
C. $1,103.88
Step-by-step explanation:
The total cost is:
1785.42 × 1.06635 = 1903.88
There was no physical damage to the pool, only an accidental injury. So Opal pays the $800 deductible, and the insurance pays the rest, which is:
1903.88 − 800 = 1103.88
