(3*30) + (2*70) = 230
Answer:
Step-by-step explanation:
I think that it’s A, Perpendicular (correct me if I’m wrong)
12×5=60 3×20=60
60-60=0 So the answer is 0
Using f(x) = y, we know that a graph of the function contains the (x,y) points (2,5) and (6,-1). first find the slope of that line,
m = (y2 - y1)/(x2 - x1) ⇒ -6/4⇒-3/2
then using either point (I'll use the first one) solve for b in y = mx + b.
5 = (-3/2)(2) + b⇒ 5 = -3 + b⇒ 8 = b.
So y = (-3/2)x + 8 ⇒ f(x) = (-3/2)x + 8.
