1. x=-3 y=4 2. x=5/2 y=15/2 3. x=9/5 y=-36/5 4. x=-2 y=1
We can set up a proportion.
32/128 = x/100
32 * 100 = 3200
128 * x = 128x.
Now we have 128x = 3200.
All we need to do is divide 3200 by 128, so 3200 / 128 = 25, so your answer is 25%.
Answer:
7
Step-by-step explanation:
Note that when x=0, y=-6, so d cannot be right. Note that 2 and -1.5 are solutions. The only answer choice that has both as zeroes is a.
