Answer:
7 cakes and 8 pies
Step-by-step explanation:
To solve, write two equations: one for the total number and the other for the total sales.
Let c be the number of cakes.
Let p be the number of pies.
So c + p =15, the total sold.
And 5c + 7p = 91 for the total $ sales.
Solve by substitute one equation into another.
c + p = 15 becomes c = 15 - p. Substitute it into 5c + 7p = 91.
5(15-p) + 7p = 91
75 - 5p + 7p = 91
75 + 2p = 91
2p = 16
p=8
To find c, substitute p=8 into c = 15 - p.
c = 15 - 8
c = 7

Answer:
<h2>The slope is undefined</h2>
Step-by-step explanation:
The slope of a line given two points can be found by using the formula

where
(x1 , y1) and (x2 , y2) are the points
From the question the points are (-11, -19) & (-11, -10)
The slope is

Any number divided by zero is undefined so the slope of the line here is undefined.
Hope this helps you
Sorry can u be more specific thank you
