Answer:
a = 3, b = - 7
Step-by-step explanation:
Substitute x = 2 into the equation and equate to 5, that is
a(2)² + b = 5
4a + b = 5 → (1)
Substitute x = 3 into the equation and equate to 20
a(3)² + b = 20
9a + b = 20 → (2)
Subtract (1) from (2) term by term to eliminate b
(9a - 4a) + (b - b) = (20 - 5), that is
5a = 15 ( divide both sides by 5 )
a = 3
Substitute a = 3 into either of the 2 equations and solve for b
Substituting in (1)
4(3) + b = 5
12 + b = 5 ( subtract 12 from both sides )
b = - 7

Answer:
<u>$911.25</u>
Step-by-step explanation:
We know:
1 yd = 3 feet
So, 1 cubic yards should be *THREE* times the power of what the initial scale factor is, 3 cubed. That would make it:
1 yd = 3 feet
1^3 yd = 3^3 feet
1 cu. yd. = 27 cu. ft.
That means, the price of 1 cubic feet of sand is 27 times of the price of 1 cubic yd price
33.75 * 27 = <u>$911.25</u>
