Answer:
815
Step-by-step explanation:
First you put the value of x from the table into the formula provided.
<em>y = -670 + 33(x) </em><= plug in the x value from the table
<em>y = -670 + 33(45)</em> <= multiply 33 * 45
<em>y = -670 + 1485</em> <= add the two terms (which you will subtract because one is positive and one is negative.
<em>y = 815</em>
The answer is 1.5 months
explanation:
5/2 = 2.5
15/4 = 3.75
2.5 per month
3.75 per x months
x = (3.75×1)/2.5
x = 3.75/2.5
x = 3/2 = 1.5 months
4x-2 is the answer to 3x+2+x-4
Answer:
2L^2 - 27L + 70 = 0.
Step-by-step explanation:
p = 2(L + W)
27 = 2L + 2W
2W = 27 - 2L
W = (27 - 2L)/2
Substitute for W in the area equation:
A = LW
35 = (27 - 2L) * L / 2
L(27 - 2L) = 70
-2L^2 + 27L - 70 = 0 Multiply through by -1:
2L^2 - 27L + 70 = 0
Answer:
d = -15
Step-by-step explanation:
The slopes of perpendicular lines have a product of -1.
1/3·d/5 = -1
d/15 = -1 . . . . simplify
d = -15 . . . . . multiply by 15
