This is an equilateral triangle (a triangle with 3 equal/congruent sides and 3 congruent angles)
Since you know the sides have to be the same/equal to each other, you can set the sides equal to each other (you can just do two because all of the sides are suppose to be the same anyways)
BC = AC
5x = 3x + 6 Subtract 3x on both sides
2x = 6 Divide 2 on both sides
x = 3
Answer:
(0,0)
Step-by-step explanation:
Answer:
B'(6, 6) ; C'(12, 6)
Step-by-step explanation:
The points are not labeled so I'm going to assume the points are as follows:
A(3, 9)
B(3, 3)
C(6, 3)
In order to dilate with a scale factor of 2, simply multiply the x and y coordinates by 2.
B(3, 3) ⇒ B'(6, 6)
C(6, 3) ⇒ C'(12, 6)
Answer:
Step-by-step explanation:
Going from (1, -2) to (3,6), x increases by 2 and y increases by 8. Thus, the slope m of this line is m = rise / run = 8/2 = 4.
I think you meant, "What is the EQUATION of the line that passes through the point (-1, 1) and is parallel to a line that passes through
(3, 6) and (1, -2)? We have seen that this slope is -4.
Starting with the point-slope equation of a line, we have:
y - 6 = -4(x - 3)
