15% of 30 = 4.5
30% of 45= 13.5
60% of 7= 4.2
23% of 20= 4.6
To get y you can move the x's to one side, so 120y=500-35x
then you can isolate the y, y= 500/120-35x/120

Answer:
a 
b 
c 0 customers
Step-by-step explanation:
Given
per customer
Solving (a): Amount (A) on n customers
This is calculated as:
Solving (b): Amount on 134 customers
In this case: n = 134
So:
Solving (c): Customers at noon.
At noon, the amount is 30.
So:
Collect like terms
Answer:
x2 - 4x - 4
———————————
x - 2
Step-by-step explanation:
Use desmos graphing calculator, for visuals. It's easy to use as well.
A is 0 (zero)
(1x1 + 2x1 - 3)
B) D ( lies on 1 on our x-axis)
C) This tells you to draw a line at zero on the y-axis, a horizontal line BTW & read off the x values, where the line touches the pink graph/diagram.
y=x^2+2x-3 is the similar to x^2+2x-3=0 because the letter y now represents zero. So, that's why we draw the line y=0 (a horizontal line at zero). Then, use it to find the x values.
Thus, x = - 3 & x = 1
Hope this helps!
