Answer:

D. 5

E. 7

Step-by-step explanation:

X^2-6x+40=6x+5

Bring all the terms to one side

Subtract 6x from each side

X^2-6x-6x+40=6x-6x+5

x^2 -12x+40 = 5

Subtract 5 from each side

x^2 -12x+40-5 = 5-5

x^2 -12x+35 =0

Factor

(x-5) (x-7)=0

Using the zero product property

x-5=0   x-7=0

x=5  x=7

If a line goes through the point (8,9) and has a slope of negative 3/4 what is the starting value?
scZoUnD [109]

I assume by starting value, you mean y-intercept. The y-intercept is 15

To find this, we need to use slope intercept form and the given information to find it.

y = mx + b ----> plug in the known values

9 = -3/4(8) + b

9 = -6 + b

15 = b

Therefore, the starting value is 15.
