Step-by-step explanation:
Step 1: 180degree-99degree
answer gives you 81degree
First, find the slope between the two points.
Slope = y2-y1 / x2-x1
-4+3/ -12+9
-1/-3
1/3 is the slope of this equation.
You do not have to go any further to find b or the y-intercept because it appears that b or the y-intercept is 0 in this case.
y= 1/3x or in other words y= x/3
Answer:
No, they are not equivalent
Step-by-step explanation:
8x + 3(x + y)
8x + 3x + 3y
11x + 3y
7x + 7y + 4x + 4y
11x + 11y
They are not equivalent because in one of the equations, the like terms add up to 11y which is different from the other equation which adds up to 3y.
I hope this helps.
I believe the answer is yes. Hope that helps!
