Answer:
1 plain = $0.75; 1 cheese = $0.95; 1 super = $1.25
Step-by-step explanation:
We have three conditions
(1) 5P = 3S
(2)  S = C + 0.30
(3)  P = C – 0.20                           Substitute (3) into (1)
=====
(4)   5(C – 0.20) = 3S                   Substitute (2) into (4)
       5(C – 0.20) = 3(C + 0.30)     Remove parentheses
          5C – 1.00 = 3C + 0.90       Add 1.00 to each side
                     5C = 3C + 1.90        Subtract 3C from each side
                     2C = 1.90                 Divide each side by 2
                       C = $0.95              Substitute C into Equation (2)
=====
                       S = 0.95 + 0.30
                       S = $1.25               Substitute C into Equation (3)
=====
                      P = 0.95 – 0.20
                      P = $0.75
1 plain = $0.75; 1 cheese = $0.95; 1 super = $1.25
 
        
             
        
        
        
The answer is D. because first you got solve the problem.
y=2.5x
(turn y to 0)
0= 2.5x
÷2.5  ÷2.5
_________
0=x
So we got one answer (0,0) 
y=2.5x
(turn x to 0)
y= 2.5(0)
 y=2.5
(2.5, 0)
When you do (0,0) (2.5,0) on the graph it will look like D.)
        
             
        
        
        
<h3>
Answer: choice B) counterclockwise rotation of 90 degrees around the origin</h3>
To go from figure Q to figure Q', we rotate one of two ways
* 270 degrees clockwise
* 90 degrees counterclockwise
Since "270 clockwise" isn't listed, this means "90 counterclockwise" is the only possibility.
