Since its adding and subtracting just add the coefficients of similar terms (coefficient is the number in front, term is the coefficient and variables, similar terms are terms that have the same variables)
3ab-9ab+7ab
3-9=-6: -6ab+7ab
-6+7=1: 1ab or ab :)
Answer:
C. -1/2
Step-by-step explanation:
well the formula for slope is m=(y2-y1/x2-x1). y2 = -5 y1= 3 x2 = 2 x1 = -14. put that all together to get -5-3/2-(-14). well -5 - 3 = -8. the second one is like a multiplication problem so a negative minus a negative is a positive. which give u 2 + 14 = 16. so you get the fraction -8/16 both are divisible by 8 so divide the equation by 8 and you get -1/2.
Answer:
x = -3
Step by step explaination-
3(2(-3) + 4) = -6
Answer:
x=130 I believe
Step-by-step explanation:
28+8+14+x=180
50+x=180
x=130
(x-3)^2=(3x+10)*(x-3) so to solve this u can simply take (x-3) over to the other side so it will; look like this
(x-3)^2/(x-3)=3x+10
then it will be x-3=3x+10
-2x=13
x=-13/2 which is -6.5
