75/4=25 pages per hour, so, now we have to divide 250 by 25.
250/25=10
So, it would take Joan 10 hours to read 250 pages. :)
Step-by-step explanation:
px^2-qx+r
p(x^2-q/px)+r
p[(x^2-q/px +(q/2p)^2_(q/2p)^2)]+r
p[(x-q/2p)^2 -q^2/4p^2)]+r
p(x-q/2p)^2 -q^/4p+r
p(x-q/2p)^2-(q^2-4pr)/4p
Step-by-step explanation:
I take it this is meant to be a multiplication, right ?
not a "function of function", which would be symbolized by a little empty circle.
to multiply 2 function means basically the same as to add, subtract or divide 2 functions : to apply the arithmetic operation in both expressions.
(f×g)(x) = (-2x² + 4x)(x² + 18x + 77) =
= -2x⁴ - 36x³ - 154x² + 4x³ + 72x² + 308x =
= -2x⁴ - 32x³ - 82x² + 308x
weight loss is negative weight gain is positive
198 -5 -2.5 -2.5+3.5 = 191.5 lbs
Answer:
D, infinitely many solutions
Step-by-step explanation:
1. multiply out
5(x-3) = 5x-15
2. combine like terms
5x-15-3x=8x-15-6x = 2x-15=2x-15
they are equal so there are infinite solutions.
