<span>The correct answer is that y does not vary directly with x.
Explanation<span>:
If y varies directly with x, this means that it would fit the equation y=kx for every point in the set.
For the first point, we would have 11=7k; this would mean that k=11//7.
For the second point, we would have 13=8k; this would mean that k=13/8.
Checking using proportions shows us that 11/7 does not equal 13/8:
cross multiply, and you have 11*8=7*13, or 88=91.
This is not true, so k is not a constant, and y does not vary directly with x.</span></span>
Answer:
3315
Step-by-step explanation:
Given the data:
WEEK ________1 _____2______3______4
no of books __1412___1531 ___2050 ___1785
Number of books sold in weeks 2 and week 4
Books sold in week 2 = 1531
Books sold on week 4 = 1785
(1531 + 1784) = 3315
Your answer would be -3/4
Answer:
Right 2, up 3
Step-by-step explanation:
In the vertex form transformations....
f(x) = a(x-h)²+k
- a - indicates <em>vertical stretches</em>, <em>compression</em>, and/or a <em>reflection across the x-axis</em>.
- h - indicates only on the <u><em>x-axis</em></u>. Negative = Goes right, Positive - goes left
- k - indicates only on the y-axis. Positive = up, negative = down
