X and y vary inversely means y is inversely proportional to x, this means:
y=k/x, where k is a constant.
We are given that when x=-4, y=7/2, we replace these values to find k.
7/2=k/-4
k= (-4*7)/2=-14
So we have y=-14/x
Therefore, when x=4, y=-14/4= -7/2
Answer:
y=-x+2.5
Step-by-step explanation:
Answer:
y - 0.32y = 0.68y
y + 0.32y = 1.32 y
Step-by-step explanation:
To simplify expressions, add/subtract using the coefficients of the terms.
y – 0.32y should be 1 - 0.32 = 0.68. This simplifies to 0.68y.
y + 0.32y should be 1 + 0.32 = 1.32. This simplifies to 1.32y.
Answer:
C. Tasha's balloon was farther from the town at the beginning, but
Henry's balloon traveled more quickly.
Step-by-step explanation:
<span>The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 39 are 1, 3, 13, and 39. A GCF, or greatest common factor, is the largest (greatest) number that divides two numbers. From the lists, we see that this is 3. If we factor out the 3 from both 12 and 39 essentially undoing the distributive property, we are left with the product 3 * ( 4 + 13 ).</span>
