Consider the quadratic function y=x^2-4x-5. how many solutions does the equation have

Hello from MrBillDoesMath!

Two solutions

Discussion:

y = x^2 -4x -5 = (x-5)(x+1)

so it has two solutions ( x = 5 and x = -1)

Thank you,

MrB

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
