Answer:
(x, y) = (3, 26)
Step-by-step explanation:
I like to solve systems of equations like this by graphing. A graphing calculator easily shows the solution for both x and y.
(x, y) = (3, 26)
__
As an alternative, here, the equations can be subtracted.
y = f(x)
y = g(x)
0 = f(x) - g(x) . . . . subtract the second equation from the first
0 = 11x -7 -(3x +17)
0 = 8x -24 . . . . simplify
0 = x -3 . . . . . . .divide by 8
3 = x
Now, we can substitute into either equation:
y = g(x) = 3(3) +17 = 26
The solution is (x, y) = (3, 26).
Answer: 35 aisles
Step-by-step explanation:
There are 50 aisles.
70% of them are empty.
Total empty therefore is:
= 70% * 50
= 35 aisles

Answers in order top to bottom:
8
6
-8
__________
The equation can be simplified by dividing both sides by 2
remember, anything times 0 is 0.
4x + 3y = 24
Now plug in values
if x = 0;
4(0) + 3y = 24
3y = 24
y = 8, this is the first answer
if y = 0;
4x + 3(0) = 24
4x = 24
x = 6, this is the second answer
if x = 12;
4(12) + 3y = 24
48 + 3y = 24
3y = -24
y = -8, this is the third answer.
let <ACB=<C,
Here h=26 due to opposite to right angle is hypotenuse and b=10 Is a base and p=24 due to opposite to the angle <C
so,
Cos<C=b/h
=10/26
=5/13
