Answer:
x=0.9
Step-by-step explanation:
1. You first have to isolate the x term so you subtract 6.814 from both sides which makes the equation 1.54x=1.386
2. Then, to isolate "x", you divide 1.54 on both sides to get rid of the 1.54 which makes x=.9
F(-3)=4(-3)^2+5(-3)-12
=36-15-12
=36-27
=-9
The perpendicular slope is 5/4x
Answer:
Step-by-step explanation:
<u>Pool:</u>
Width = x ft
Length = (x+6) ft
<u>Pool along with walkway:</u>
Width = x + 5 + 5 = (x + 10) ft
Length = x + 6 + 5 + 5 = (x + 16) ft
Total area of the pool with walkway = 950 sq.ft
length * width = 950
(x+16) * (x + 10) = 950
Use FOIL method,
x*x + x *10 + 16*x + 16 *10 = 950
x² + 10x + 16x + 160 -950 = 0 {Add like terms}
x² + 26x - 790 = 0
Can be number 1 or number 4 I am not sure but can be 4 but take your sedición
