Answer:y = 15
Step-by-step explanation:
Given y=kx,
where k is a constant
When y=8 and x=2/3, K =?
y=kx
8= k 2/3
K=(3 x8)/2= 24/2 = 12
K=12
Now when x=5/4 y=?
y= kx
y = 12 X 5/4= 60/4
y = 15
Answer:
He dropped 2 of the 3 in the last simplification and you can't do that. You can't just get rid of two of the values that make up the number. The farthest you are able to simplify is 0.333.
If you would like to simplify (2x - 2y) * (2y + 8), you can do this using the following steps:
(2x - 2y) * (2y + 8) = 2x * 2y + 2x * 8 - 2y * 2y - 2y * 8 = 4xy + 16x - 4y^2 - 16y
The correct result would be b. 4xy + 16x - 4y^2 - 16y.
Answer:
x = 12, 30, 15
y = 7, 25, 10
Step-by-step explanation:
y = x - 5
When y = 7,
7 = x - 5
Add 5 to both sides
7 + 5 = x - 5 + 5
12 = x
When y = 25,
25 = x - 5
25 + 5 = x - 5 + 5
30 = x
When x = 15,
y = 15 - 5 = 10
Answer:
x intercept: ( , 0)
y intercept: (0, 5)
