5(x-2)^2-29=-14 what does x equal
eimsori [14]

Answer:

x = 2+\sqrt{3}

Step-by-step explanation:

5(x-2)^2= 15 ←add 29 on both sides

(x-2)^2= 3  ← divide by 5 on both sides

x-2= \sqrt{3}   ← find the sq root of both sides

x= 2+\sqrt{3}   ← add 2 on both sides

On a coordinate plane, line M N goes through points (2, 3) and (negative 3, 2). Point K is at (3, negative 3). Which point could
Fynjy0 [20]

MN goes through

  • (2,3)
  • (-3,2)

Slope:-

  • m=2-3/-3-2=-1/-5=1/5

Slope of perpendicular line:-

  • -5

Passes through k(3,-3)

Equation in point slope form

  • y-y1=m(x-x1)
  • y+3=-5(x-3)
  • y+3=-5x+15
  • y=-5x+12

Check one by one

  • 0=-5(-12)+12=60+12=72
  • 2=-5(2)+12=-10+12=2

Yes option B is correct
