Answer:
We start with this equation:
If x intercept is -4 then y = 0 giving us another point (-4, 0)
(4, -7) and (-4, 0)
slope = y difference / x difference = (-7 -0) / (4 --4) =
-7 / 8
Step-by-step explanation:
First you want to combine like terms. on the first equation we can combine 2x+x=3x. So now we have 3x-3. On the right side we can combine 12+1 so we now have -x+13. Now we will take add an x to -x so it's 0 but we have to do it to the other side as well so now we have 4x-3=13. now we will add three to -3 to make it 0 but again we have to do it to the other side. Now we have 4x=16. We want to figure out what x is so we now divide 4x by 4 so we are just left with x but we need to do it to the other side so your answer is x=4
Answer:
It is SSS
You already have the two sides, and you can see the two triangles share a common line. Therefore you know the unknown is a side.
