Answer:
The car makes a complete revolution in 8 s.
Hello :
<span>x²- y = 3 ...(1)
x - y = -3 ...(2)
by (2) : y = x+3
subqct in (1) : x²-x-3 = 3
x²-x-6 =0
(x+2)(x-3) = 0
x+2 =0 or x-3 =0
x=-2 or x=3
if x = -2 y = -2+3 = 1
if x=3 y =3+3 = 6
two solutions : ( -2, 1) , (3,6)</span>
Answer:
$8 per yard of fabric
1 yard is equal to 3 feet
8 divided by 3 = 2.67(rounded)
$2.67 per foot of fabric
1 foot is equal to 12 inches
2.67 divided by 12 =0.22(rounded)
1 inch of fabric cost $0.22
Answer: y= 2x + 7
Step-by-step explanation:
Slope intercept form = y= mx + b
You are given slope (m=2) and a point (0,7) so
7 = 2(0) + b
7 = b;
So your equation is y= 2x + 7
