They are reflected across the y-axis.
The measure of angle ABC is 100 because all you do is add the 60 to the 40 and get 100.
Answer:
(-7, -4)
Step-by-step explanation:
The midpoint formula is expressed as;
M (X,Y) = {(x1+x2/2), (y1+y2)/2}
Given that M(-4, -3) and (x1, x2) = (-1, -2)
X = x1+x2/2
-4 = -1+x2/2
-8 = -1 + x2
x2 = -8 + 1
x2 = -7
SImilarly;
Y = y1+y2/2
-3 = -2+y2/2
-3*2 = -2+y2
-6 = -2 + y2
y2 = -6 + 2
y2 = -4
Hence the coordinate of B is (-7, -4)
Answer:
There is no solution
Step-by-step explanation:
The slopes are the same and the y-intercepts are different.
Think of this as the slope as an amount you get per week and y-intercept as how much you start off with. You have a friend that starts off with 10 dollars and gains 5 dollars every week and you start off with 5 dollars and gains 5 dollars every week. Will you ever catch up to your friend if you and your friend don't spend any money? I don't think so. The solution to a set of equations is when both equations have the same y value with the same x value.
