Evaluate 7r -\dfrac{15}s7r− s 15 7, r, minus, start fraction, 15, divided by, s, end fraction when r=3r=3r, equals, 3 and s=5s=5s,

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

step-by-step explanation:

1. the cylinder is a. 54

2.   a.108 /

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
