  • y^2+9y+20
  • y^2+10y+21
  • y^2+2y+3
  • Step-by-step explanation:
  1. (y+5(y+4) =y(y+4)+5(y+4) =y^2+4y+5y+20 =y^2+9y+20
  2. (y+3(y+7) =y(y+7)+3(y+7) =y^2+7y+3y+21 =y^2+10y+21
  3. (y+3)(y-1)

=y(y-1)+3(y-1)

=y^2-y+3y-3

= y^2+2y+3

Write the equation of the line in y=mx+b that passes through the points (5,10) and (6,12)
Damm [24]

Answer:

y = 2x + 0 or y = 2x

Step-by-step explanation:

use slope-intercept form \frac{y2 - y1}{x2 - x1}

12 - 10 = 2

6 - 5 = 1

m value = 2/1 = 2

y=2x+b

to find b plug one of the points in for x and y

Example: 10 = 2(5) + b

solve equation

10 = 10 + b

subtract 10 from both sides

0 = b

Equation of line equals y=2x+0 or simply just y=2x
