Answer:
sorry I dont know
Step-by-step explanation:
Answer: I think the answer would be b) 24+2x=5x
sry if it's wrong
B
Graph b is the only graph showing a pair of parallel lines.
Graph A are perpendicular lines and the other two are graphs that intersect. Parallel lines do not intersect each other.
Answer:
Sum of the solutions of 
is -9.
Product of the solutions of 
is 
Step-by-step explanation:
1.
Given:
The expression whose sum of the solution is required is given as:
For a quadratic equation of the form 
the sum of the solutions is given as:
Sum = 
Here, 
Therefore, the sum of the solutions = 
2.
Rewriting the above equation in a standard quadratic equation, we get:
For a quadratic equation of the form the product of the solutions is given as:
Product = 
Here, 
Therefore, the product of the solutions = 
Answer:
The 1st one is y = 11.
The 2nd one is y = 5.
The 3rd one is v = -5.
The 4th one is y = 9.
Step-by-step explanation:
1) -38 = 7y + 17 - 12y
-38 = -5y + 17
-55 = -5y
11 = y
2) 5y + 6 - 12y = -29
-7y + 6 = -29
-7y = -35
y = 5
3) -12v - 9 + 7v = 26
-5v - 9 = 26
-5v = 35
v = -5
4) -5y + 2(y + 2) = -5
-5y + 4y + 4 = -5
-y + 4 = -5
-y = -9
y = 9
