X^2 + 7x + 10
Find the factors of 10 that add up to 10.
1* 10, 2*5
The factors are 2*5
(x+2)(x+5)
Solving the system of equations we get solution set (38/11,26/11)
Step-by-step explanation:
We need to solve the system of equations:
Let:
Multiply equation 2 with 5 and subtract both equations to find value of x:
So, value of x = 38/11
Now, finding y:
Putting value of x in equation 2
So, value of y = 26/11
So, Solving the system of equations we get solution set (38/11,26/11)

Answer:
x = 17
Step-by-step explanation:
x + x + 8 = 42 because x = boys and x + 8 = girls
2x = 34 because 2x = 42 - 8
x = 17
i hope this helps! you don't need the 2x = 42 - 8 to be an equation ;)
Answer:
Slope of the line= -1
Step-by-step explanation:
The given line is of equation y= -x
Slope of any line= y/x
= -x/x= -1
