Jemma wants to solve the following system using the elimination method:

y = x − 6
y = 6x − 19

What number should the equation y = x − 6 be multiplied by to eliminate x?

Kylie explained that (-4x+9)^2 will result in a difference of squares because (-4x+9)^2 (-4x+9)^2 =(-4x)^2+(9)^2=16x^2+81

An initial investment of $100 is now valued at $150. the annual interest rate is 5%, compounded continuously. the equation 100e0.05t = 150 represents the situation, where t is the number of years the money has been invested. about how long has the money been invested? use your calculator and round to the nearest whole number. years

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)
