Answer:

x = 1

Step-by-step explanation:

As you might guess, the zeros are symmetrical about the axis of symmetry. That is, the axis of symmetry is midway between the zeros, so will be their average value:

x = (-2 +4)/2 = 1

The axis of symmetry is x = 1.

If 8 out of 20 students in a class are boys,what percent of the class is made up of boys

lara31 [8.8K]

Answer:

40%

Step-by-step explanation:

First, divide 100 by 20. You do this because you need something out of 100 to equal a percent. (Example- 50 out of 100 is 50%)

Next you need to take the number you got from dividing (5) and multiply that with 8. This leaves you with 40/100 or 40%.

Hope this helps!

Help... anyone????????

katovenus [111]

Since they both have 3x terms subtract the second from the first to get rid of the x terms...

3x+2y=10
-3x+y=-13
__________
3y=-3

y=-1, which makes 3x+2y=10 become: 3x-2=10 so

x=4

So the solution is the point (4, -1)
