"A solution to -x + 10 =2x + 4 is 8" true or false?

False, x=2

Step-by-step explanation:

-x + 10 =2x + 4

Add x on both sides:

-x+x+10=2x+x+4

10=3x+4

Subtract 4 on both sides:

10-4=3x+4-4

6=3x

Divide 3 on both sides:

6/3=3x/3

2=x

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
