Well to find out X, you have to do the opposite to what it's asking to each side. So 11=x-4
+4 onto the 11 and + 4 on to the -4 which means you just have 15=X
Ok so 50 points a day that’s a lot of points
It's just a variable in a problem. You solve for ex . So whatever your answer is you equal to x.
Answer:
u=-5
Step-by-step explanation:
Slope is y(2)-y(1)/x(2)-x(1). So, your equation is u-10/-2-1. -2-1=-3, so the top number has to be negative to get a positive and has to be 5 times more than three. So, the numerator for the slope would be -15, because -15/-3=5. So, u is equal to -15-10. Therefore u equals -5.
(hope this helps :P)
