Her book was 10 days late. D = days. The equation is .25(4) + .30d = 4.00. First you multiply .25 • 4 to get 1. Then you subtract 1 from both sides and get .30d = 3. Next you divide both sides by .30 to get d = 10.
Answer:
$24
Step-by-step explanation:
What you do is you just times 84 x 2/7 to get your answer.
84 x 2/7=$24 is your answer.
perpendicular means negative reciprocal so it would be -1/3
General form is ax^2+bx+c, and to get there we need to factor using FOIL (First Outside Inside Last)
(2x-1)(x+5)
F (2x × x)= 2x^2
O (2x × 5) 10x
I (-1 × x) -x
L (-1 × 5) -5
now add them together
2x^2+10x-x-5
2×^2+9x-5
and because the equation is in the form
ax^2+bx+c b is equal to 9
