Solve the system of equations
2y + 2x = 5
y = 2x - 7

Aheated piece of metal cools according to the function c(x) = (.5)x ? 7, where x is measured in hours. a device is added that aids in cooling according to the function h(x) = ? x ? 2. what will be the temperature of the metal after two hours?

What is the solution to the division problem below x3+x2-11x+4/x+4

Pls never taught i’m really confused and i rlly need
