Answer:
B
Step-by-step explanation:
If 12 pencils are 1.25, 24 would be 2 x 1.25. And 4 notebooks worth 0.65 would be 4 x 0.65
Added up, this expression is:
(2 x 1.25) + (4 x 0.64)
Y intercept occurs when x = o so it is -2(0-3) + 4 = -2
x intercepts:-
-2(x - 3)^2 + 4 = 0
(x - 3)^2 = -4/-2 = 2
x - 3 = +/- sqrt2
x = 3 + sqrt2 and 3- sqrt2
In order to get the constant of variation, you can either
make a linear equation that relates x and y in which the slope is the constant
of variation
LINEARIZING
x = 3y
the slope of the equation is 3 and therefore the constant of
variation is 3
