Write the equation for the red part of the piecewise function. Ex: f(x) = mx+b

1 answer:

3 0

The easiest way is to compare two different whole-number points. So, the first one is (0,2) and the other is (3,3), meaning that it's 3 right, 1 up. This means that the slope is ⅓. (⅓x)
Next is the point that intercepts the y-axis. In this case, at x=0 y=2. (+2)

So, the equation for the red part is ⅓x+2

X= be coffee

Y=be donuts

Set up equations

10x+5y=16.50

5x+10y=14.25

Now multiply first equation by -2 to get a negative

(-2)10x+5y(-2)=16.50(-2)

-20x-10y=-33

Now put both equations to solve for x

-20x-10y=-33

5x+10y=14.25

___________

-15x. = -18.75

Now divide -15 bith sides to get x alone

X= -18.75/-15

X= 1.25

The cost of each coffee cup$1.25
