11) give the slope-intercept form of the equation of the line that is perpendicular to 5x + 2y = 12 and contains the point (2, 3).

12) tell whether the lines are parallel, perpendicular, or neither.
the line through (-3, 2) and (4, 6) and the line through (-5, 7) and (-9, 14)

13) which two lines are parallel?
3x + y = -2
2y – 6x = 4
2y = -6x – 8

this is answer of 144 cubic meters

answer

idk wbu

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
