Answer:

no solutions

Step-by-step explanation:

−2a + 2a + 7 = 8

Combine like terms

7 = 8

This is never true so there are no solutions

Infinitely many, as -2a + 2a cancel each other out, so it doesn’t matter what a is currently equal to.

Answer:

Step-by-step explanation:

slope m = (y₂ - y₁)/(x₂ - x₁)

             = 6-6 / 8 - (-5) = 0/ 8+5 = o

Slope = o. ie the line is parallel to the x-axis.

Answer:

the tree is 8.8 m tall

I can't draw it but it will be two similar acute triangles. The one that represents the man will have a 2m height and a 5m base. The one that represents the tree will have an 8.8m height and a 22 m base.

Step-by-step explanation:

it's a proportional relationship

5/22=2/height

5(height)=2(22)

5(height)=44

divide both sides by 5

5(height)/5=44/5

height=8.8 m

To determine whether a solution a set of a system of linear inequalities is right, you simply plug back into the equation to check your work. If the solution equals and is mathematically correct, then that's the answer. For Example, use the equation,

5x = 10

Let's say you got an answer of x = 4. Plug it back into the equation 
5(4) ≠ 10. As you can see the answer is wrong. This shows you that the answer is wrong. 

The correct answer is x = 2
