Answer:
y = 1/4x
Step-by-step explanation:
y = amount of cubic feet = 15 cubic feet
x = time taken = 60 seconds
y = kx
Where,
k = constant of proportionality
y = kx
15 = k * 60
k = 15/60
k = 1/4
The equation
y = kx
Where
k = 1/4
Becomes,
y = 1/4x
Answer:
2/3
Step-by-step explanation:
Step 1:
4 ( 3x - 2 ) - x = 3x - 4x
Step 2:
12x - 8 - x = - x
Step 3:
11x - 8 = - x
Step 4:
11x = - x + 8
Step 5:
12x = 8
Answer:
x = 2/3

Answer:
The transformation on the graph is a reflection across the x-axis.
Step-by-step explanation:
A reflection is a transformation representing a flip of a figure. Figures may be reflected in a point, a line, or a plane. When reflecting a figure in a line or in a point, the image is congruent to the preimage. A reflection maps every point of a figure to an image across a fixed line.
In this particular figure, you see that each point is the same number of units away from the x-axis. For instance, with A and A' their both 1 unit away from the x-axis. So this is an automatic indicator that this transformation is a reflection.
Answer:
y axis
Step-by-step explanation:
When you set up an ordered pair, yi always has to be - 1 and x can be anything. To show you what this means, draw an x,y axis.
Plot a few points. Try these (0,-1) (2,-1) and (-2,-1) Now join them. They make a straight perpendicular line.
The line is parallel to the y axis.
A line parallel to the x axis has all the x's the same.
(-1, 1), (-1,2) (-1,4)
