1. D; -5m+2m, because -5+2=-3
2. B; 4 terms, every part of an expression that's not the subtraction/addition sign counts as a term.
3. Not 100% sure about this one, but I'll go with B; 4x².
4. C; 5b, that term cannot be combined because the variable is different from the rest.
I hope this was helpful.
The slope formula is y2-y1/x2-x1, this is considered rise over run. Simply subtract the y2 variable from the y1 variable, 1-(-1) =2 and then subtract the x2 variable from the x1 variable, 2-1 = 1. From there, ride (y) is on top and run(x) is on the bottom. Divide 2/1 which equal 2. The slope of this line is 2.
Hope this helped :)
Answer:Thats Just Notes To Right Down.
Step-by-step explanation:
The slope-intercept form is y=mx+b y = m x + b , where m m is the slope and b b is the y-intercept. Using the slope-intercept form, the slope is 45 4 5 . The equation of a perpendicular line to y=4x5+7 y = 4 x 5 + 7 must have a slope that is the negative reciprocal of the original slope.
6u + 3u = 18
9u = 18
u = 18/9
u = 2
That is called a cyclic quadrilateral. Angles E and G add up to 180 degrees and angles H and F add up to 180 degrees.
