Answer:
Where are the graphs?????
Step-by-step explanation:
Answer:
(7,5)
(9,5)
(11,5)
(13,5)
Step-by-step explanation:
For the first step we plug in x
y=2(1)+5
y=7
y=2(2)+5
y=9
y= 2(3)+5
y=11
y=2(4)+5
y=13
Since the plus 5 is the y intercept we put that in the ordered pair like so:
(7,5)
(9,5)
(11,5)
(13,5)
Answer:
39 ft²
Step-by-step explanation:
11 ft × 3 ft = 33 ft²
2 ft × 3 ft = 6 ft²
33 ft² + 6 ft² = 39 ft²
Problem 1
Answer: Direct variation; k = 1/4
----------------------
Explanation:
We can rewrite the given equation y = x/4 into y = (1/4)x. Then note how it's in the form y = kx. In this case, k = 1/4. In decimal form, this is k = 0.25
All direct variation equations are in the form y = kx. The value of k is the constant of variation.
====================================================
Problem 2
Answer: Inverse variation; k = 9
----------------------
Explanation:
The equation 9/y = x rearranges to xy = 9.
We can then solve for y to get y = 9/x
This is in the form y = k/x, where k = 9
All inverse variation equations are in the form y = k/x, with k as the constant of variation.
