A = L * H
A = 65
L = 2H - 3
65 = H(2H - 3)
65 = 2H^2 - 3H
-2H^2 + 3H + 65 = 0
(-Hh + 13)(H + 5) = 0
-2H + 13 = 0
-2H = -13
H = -13/-2
H = 6.5 <== height is 6.5 inches
H + 5 = 0
H = -5....this wont work because it is negative
L = 2H - 3
L = 2(6.5) - 3
L = 13 - 3
L = 10 <== length is 10 inches
Answer:
Well, i dont see a set of points, so i am assuming that you just want the equation.
Since the equation is needed to be parallel to the line y = -7/5x-1, you keep the slope, so the equation would be y = -7/5x + b
Answer:
.50
Step-by-step explanation:
To do this, set this up like a fraction and solve for x
7/9 = x/450
(7/9) x 450 = x
x= 350 students
This is like finding an equivalent fraction for 7/9 :) hope this helps! <span />
12p + 7 > 139
Subtract 7 from both sides.
12p > 132
Divide both sides by 12.
p > 11 is your answer.
I hope this helps!
