41.4 i think?!
Step-by-step explanation:
I did 2.3 * 9 then I did what that equaled which was 20.7 * 2 and got 41.4.
Answer: 
<u>Step-by-step explanation:</u>
First, find the slope of line m using the slope formula: 
(x₁, y₁) = (-5, 3) and (x₂, y₂) = (-2, -6)

Next, input the slope (m = -3) and the y-intercept
into the Slope-Intercept formula: y = mx + b

NO. Three congruent angles only proves the triangles are similar. You must have at least one side length to prove congruency.
SSS, SAS, ASA, AAS prove triangle congruency.
Answer: C
Combine like terms. -2y+y=-y. The equation is now -y-3=6. You need to get the y by itself so add 3 to both sides. The equation is now -y=9. You are solving for y so divide both sides by -1. The equation will be y=-9. The answer is y=-9. Hope this helps! ;)
