What is 5x-2.5+6x-3 equivalent to

11x-5.5

Step-by-step explanation:

If you combine like terms it will be equivalent still.

5x and 6x can be added together which is 11x

you can also combine -2.5 and -3 which is -5.5

So the product will be 11x-5.5

Hope this helped :)

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
