Answer:
Simplifying
x2 + bx + 9 = 0
Reorder the terms:
9 + bx + x2 = 0
Solving
9 + bx + x2 = 0
Solving for variable 'b'.
Move all terms containing b to the left, all other terms to the right.
Add '-9' to each side of the equation.
9 + bx + -9 + x2 = 0 + -9
Reorder the terms:
9 + -9 + bx + x2 = 0 + -9
Combine like terms: 9 + -9 = 0
0 + bx + x2 = 0 + -9
bx + x2 = 0 + -9
Combine like terms: 0 + -9 = -9
bx + x2 = -9
Add '-1x2' to each side of the equation.
bx + x2 + -1x2 = -9 + -1x2
Combine like terms: x2 + -1x2 = 0
bx + 0 = -9 + -1x2
bx = -9 + -1x2
Divide each side by 'x'.
b = -9x-1 + -1x
Simplifying
b = -9x-1 + -1x
Step-by-step explanation:
They made 4/5 with butter...that means they made 1/5 without butter.
1/5 of what is 35.2.....
1/5x = 35.2
x = 35.2 * 5
x = 176 oz
1 lb = 16 oz...so 176 oz = 176/16 = 11 lbs <===
check...
1/5 (176) = 176/5 = 35.2 oz without butter
4/5 (176) = 704/5 = 140.8 oz with butter
for a total of (35.2 + 140.8) = 176 oz, which equals 11 lbs
D. -10 cause it would be y=4x-10
