The answer is m = 250 - 25w.
This is because this answer is in y=mx+b format (slope-intercept form) and has the correct values.
In slope-intercept form, m is the slope and b is y-intercept.
In m = 250 - 25w, the y-intercept is 250 and the slope is -25.
This matches the graph.
Y-intercept is where a line crosses the y-axis, which is 250 in this case.
The slope is negative since the values are decreasing over time (as x-values increase, y-values decrease).

Kahi can eat 32 pieces of candy in 1 hr her sisters can eat the same amount in 3 hrs how long will it take both them togethr to

pantera1 [17]

So, in order to find the answer, this is what we are going to do.
Let K be the number of candies that Kahi can eat per hour and S be the number of candies that her sisters can eat per hour.
So for the sisters, let us divide 32 by 3 and we get, 10.67. so 10.67/ hour.
Now, consider this expression: (K+S)*h = 32
Plug in the given values.
(32 +10.67)h = 32
42.67h = 32
Divide both sides by 42.67 and we get
h= 1.33. Therefore, it will take 1.33 hour for both of them together to eat 32 candies. Hope this answer helps.

Answer:

Q' = (-4, -2)

R' = (4, -2)

S' = (4, 2)

T' = (-4, 2)

Step-by-step explanation:

First, we can create a matrix to scale this rectangle by putting all the x coordinates in the top row and all the y coordinates in the bottom row and multiply it by 4.

Our initial matrix to multiply:

$4\left[\begin{array}{cccc}-1&1&1&-1\\-2&-2&-1&-1\end{array}\right]$
