How much of each is needed to make the bread?
Answer:
Sixteen
Step-by-step explanation:
Up to 2 integers can have the same absolute value (a number and its opposite).
For example, 2 and -2 have the same absolute value. 5 and -5 also have the same absolute value.
Solving for X:
1) y=-8x+6.5 y=-4x+11
2) -8x+6.5=-4x+11
3) -8x=-4x+11-6.5 (Subtract 6.5 from both sides)
4) -8x+4x=11-6.5 (Add 4x to both sides)
5)-4x=4.5
5)x=-1.125
Solving for Y:
y=-8(-1.125)+6.5
y=9+6.5
y=15.5
y=-4(-1.125)+11
y=4.5+11
y=15.5
x=-1.125
y=15.5
or
(-1.125,15.5)
71. answer is zero (0).
72. answer is negative six (6)
