Y=2x-4
X=2
X+2y=10
X+2x0=10
X+0=10 therefore, x=10
Answer:
Constant of proportionality is
Equation is
================================================
Explanation:
The general equation they give is c = rg
Solving for r leads to . We divided both sides by g to get this.
Now pick any point on the diagonal line. I'll pick (3,10)
The graph shows the horizontal axis is g and the vertical axis is c. The point (3,10) means g = 3 and c = 10 pair up together.
Making r to be,
and the equation in the form c = rg would be
Answer:
4
Step-by-step explanation:
4 times itself equals 16.
For this case we define variables:
x: roast beef sandwiches
y: chicken salad sandwiches
We write the system of equations:
x + y = 30
5x + 3y = 120
Solving the system we have:
x = 15
y = 15
The profit is:
P = 3 * (15) + 2 * (15)
P = 75 $
Answer:
should be prepared to maximize the profit:
15 roast beef sandwiches
15 chicken salad sandwiches
Answer: 7 & 10
Step-by-step explanation:
7+10=17
10-7=3
