Answer:
y=1/2x+5
Step-by-step explanation:
y-y/x-x for slope
4-3/-2-(-4) 1/2
Answer:
The correct answer is (-3,-1) (0,5) (3,11)
Step-by-step explanation:
Emma's mistake was flipping her y-values, 11 matches with 3, not -3. The most likely reason she did this was accidentally making the slope negative. The table she wrote fits the line y=-2x+5. If you plug in -3 into the correct equation you will get -1 and 3 will get you 11.
Answer: Scalene
Step-by-step explanation:
If the side lengths are 2, √12, and √19, the triangle is scalene, because all the sides have different lengths.

Answer:
8 1/6 < x < 20.5.
Step-by-step explanation:
Use the Triangle Inequality Theorem which states that the sum of any 2 sides of a triangle is always greater that the third side.
So for triangle to be formed:
4x + 2x - 4 > 45
6x > 49
x > 8 1/6.
Also 2x - 4 + 45 > 4x
41 > 2x
2x < 41
x < 20.5.
