Answer:
Step-by-step explanation:
Parallel lines have same slope.
y = mx + b
Slope = m & y-intercept = b
x - 5y = 15
-5y = -x + 15
y = 
so, slope = 1/5 ; (-5 , 7)
y -y1 = m(x -x1)
![y - 7 = \frac{1}{5}(x- [-5])\\\\y - 7 =\frac{1}{5}(x + 5)\\\\y - 7 = \frac{1}{5}x+5*\frac{1}{5}\\\\y - 7 =\frac{1}{5}x+1\\\\y =\frac{1}{5}x+1+7\\\\y=\frac{1}{5}x + 8](https://tex.z-dn.net/?f=y%20-%207%20%3D%20%5Cfrac%7B1%7D%7B5%7D%28x-%20%5B-5%5D%29%5C%5C%5C%5Cy%20-%207%20%3D%5Cfrac%7B1%7D%7B5%7D%28x%20%2B%205%29%5C%5C%5C%5Cy%20-%207%20%3D%20%5Cfrac%7B1%7D%7B5%7Dx%2B5%2A%5Cfrac%7B1%7D%7B5%7D%5C%5C%5C%5Cy%20-%207%20%3D%5Cfrac%7B1%7D%7B5%7Dx%2B1%5C%5C%5C%5Cy%20%3D%5Cfrac%7B1%7D%7B5%7Dx%2B1%2B7%5C%5C%5C%5Cy%3D%5Cfrac%7B1%7D%7B5%7Dx%20%2B%208)

Answer:
No because 3(5) +2= 17
3*5=15
15+2= 17
Step-by-step explanation:
I believe that x can be any real number because the equations are equal to each other.
Answer:
S = 6
R = 10
Step-by-step explanation:
Givens
Let the Regular Tickets be R
Let the Senior Citizen tickets be S
Equations
85r + 24s = 994 (1)
45r + 12s = 522 (2)
Solution
Multiply equation 2 by 2
- 2(45r + 12s = 522)
- 90r + 24s = 1044 Subtract (1)
- <u>85r + 24s = 994</u>
- 5r = 50 Divide by 5
- 5r/5 = 50/5 Do the division
- r = 10
======================
Solve for s
- 45r + 12s = 522 Substitute r = 10
- 45*10 + 12s= 522 Simplify the left
- 450 + 12s = 522 Subtract 450 from both sides
- 450-450 + 12s = 522-450 Simplify
- 12S= 72 Divide by 12
- 12S/12 = 72 Do the division
- S = 6
