Answer: No

Step-by-step explanation:  proportional means corresponding in size or amount to something. However, the number of her sit-ups isn't consistent, so it isn't proportional to the time she spends doing them.

Write the equation that is the translation of y=|x| right 7 units and down 9 units.
DedPeter [7]

Answer:

y=|x-7|-9.

Step-by-step explanation:

The given function is  y=|x|.

When this function is translated to the right 7 units and down 9 units, then the equation becomes

y=|x-7|-9.

Always remember that; y=|x-c|-k is a transformation that translates the graph of y=|x| c units to the right and k units down.

The correct choice is the first option.

What does -40x-7y=-5 equal to find Y
pickupchik [31]
The values x and y are determined when we use the substitution method.

y = x + 5

Apply eh value of y into the equation to solve for x. 

3x + y = 25

3x + x + 5 = 25

Combine like terms

3x + x = 4x

4x + 5 = 25
      -5     -5                               4x = 20

                                                 4x/4 = 20/4
                                                 x = 20/4 
                                                  x= 5

Now we know the value of x, and we need to solve for y.

y = x + 5
y = 5 + 5
y = 10
10 = 10

Now we know both of these values.

Answer:

x = 5
<span>y = 10</span>
