value of x = 20 and value of y=16
Solution set=(20,16)
Step-by-step explanation:
We need to solve system of equations:
Let:
Simplifying equation 2:
Taking LCM on left side:
Adding eq(1) and eq(3)
Putting value of x in eq(1) and finding y:
So, value of x = 20 and value of y=16
Solution set=(20,16)

Answer:
1
Step-by-step explanation:
The sum of roots of quadratic ax^2 +bx +c = 0 is -b/a. Here, that means the sum of roots is ...
-(-4)/4 = 1
The sum of the roots is 1.
<h3>
Answer: Slope = -3/7</h3>
===================================================
Apply the slope formula
m = (y2-y1)/(x2-x1)
m = (6-3)/(-9-(-2))
m = (6-3)/(-9+2)
m = 3/(-7)
m = -3/7
This means each time you go down 3 units, you go to the right 7 units.
Slope = rise/run = -3/7
rise = -3 and run = 7
In order to begin figuring that out, we need to know how both of their plans work.
