500+250x=300x
-250x=-250x
500=50x
To get the 50 away from the x you got to divide by 50 on both sides
500/50
Answer is 10=x
Answer:
B, C
Step-by-step explanation:
I am sure you have heard of the vertical line test. What the vertical line test does is make sure, for every, input, there is only one output. What this means is that two points cannot have the same x, unless they have the same y.
Two different x's can have the same y, but two different y's cannot have the same x.
In this problem, the x's that are taken by other coordinates with different y values are: 1, 3, 4, -4.
This means that the x you are trying to find cannot be any of those since the y value is different than all the other points. Which leaves you with the answers B and C.
Hope this helps, don't hesitate to ask more questions.

You can use long division or synthetic division. I am going to use synthetic division.
x - 2 = 0 → x = 2
-4.6 is greater than -4.8
Answer:
Domain is all real numbers greater than or equal to 7. Range is all real numbers greater than or equal to 9.
Step-by-step explanation:
The domain is possible x-values while the range is possible y-values. This question look like
The domain of square root function cant have a the radical inside being a negative number because we can't take the sqr root of a negative number and graph it on a cartisean plane We can take the sqr root of 0 . So we set x-7=0. And which x=7 so the domain is all real numbers that are equal to or greater than 7. The range of a sqr root function can only yield any positive y-values. So we must find the lowest point of it. Since the lowest x value we can possible use is 7 we plug it in
which equals 9. So the range is all real numbers greater than or equal to 9.
