Answer:
9) -25/21
11) 14
Step-by-step explanation:
In each case, subtract the y-coordinates. Subtract the x-coordinates in the same order. Divide the difference in y by the difference in x.
9)
y-coordinates: -10 - 15 = -25
x-coordinates = 6 - (-15) = 21
slope = (difference in y)/(difference in x) = -25/21
11)
y-coordinates: -20 - 8 = -28
x-coordinates = 3 - 5 = -2
slope = (difference in y)/(difference in x) = -28/(-2) = 14
Answer:

A box = $11
Step-by-step explanation:
Given

Represent the first order with A and the second with B.
So, we have:

Solving (a): Find B.
To find B, we make use of:

Make B the subject

Substitute values for Total and A

Open bracket

Collect Like Terms


Solving (b): Cost of a box of light bulb
This means that:

Substitute 7x + 13 for Total

Collect Like Terms


Make x the subject


X would be -14. i’m hoping that’s what you need
Answer:
I would think 28
I may be wrong but y'know
Why 28?
well it's going to touch a box every 8 boxes and 28 is the only one with 28
I hope this is right sorry if it's not.
