We know -48 came from (a)(-6), the "L" in "FOIL".
If -48 = -6a, then a = 8.
Now with a=8, go ahead and FOIL (x+8)(x-6) to find m.
Answer: 135 soccer balls
Step-by-step explanation:
In this equation, let x represent the number of soccer balls, and 7x represent the number of volley balls.
7x + x = 1,080
8x = 1,080
Now divide 1,080 by 8 to get the number of soccer balls.
1,080 / 8 = 135
In case you’re wondering how to find the number of volley balls, just multiply 135 by 7
135 * 7 = 945
It would be d because if you plug in f(6)=(3/2)+1 it would be f(6)=3+1 or f(6)=4. This works for any other of the coordinates.
Hey there!
To use the substitution method in order to solve the system of equations,
y=7x+8
y=x+20 , first notice that both equations are set equal to the same value, y.
Knowing this, 7x+8 and x+20 both equal the same value so you would set them equal to one another:
7x+8=x+20.
This would be substitution as you are substituting one of the equations in place of y.
Now, solve for x:
7x+8=x+20
6x+8=20
6x=12
x=2
Now that you know x equals the value of 2, you can substitute the value into one of the equations to find y:
y=x+20
y=2+20
y=22
Now that you have x=2 and y=22, you can conclude that your answer would be (2,22) or choice B.
Hope this helps and have a wonderful day! :)
