Answer:
5y=9x-2
y=mx-b
m=slope
y=9/5x-2/5
m=9/5=1.8 slope of pArallel
slope of pARALLEL=-1/M SLOPE OF A LINE PERPENDICULAR
m=-5/9 slope of a line perpendiculr
Answer:
Step-by-step explanation:
Since its adding and subtracting just add the coefficients of similar terms (coefficient is the number in front, term is the coefficient and variables, similar terms are terms that have the same variables)
3ab-9ab+7ab
3-9=-6: -6ab+7ab
-6+7=1: 1ab or ab :)
Volume of the box = length * width * height
length of original peice = x + 10 , width = x
length of box (x + 10) - 4 = x + 6
width of box = x - 4
height of box = 2
so we have
2 * (x -4) * ( x + 6) = 832
2x^2 + 4x - 48 = 832
2x^2 + 4x - 880 = 0
x^2 + 2x - 440 = 0
(x + 22)(x - 20) = 0
x = 20
so width of original piece of metal = 20 ins , length = 30 inches.
Answer is b because the veritable is just 1 but the 4 stays the same
