1. By combining like terms
2. Same variable = same term, so you can combine them
3. Because 2y - y = 1y , and 1y is the same as y because a y is one y (obviously)
4. 1/2 + 1/2 = 1. A half an x and a half an x makes one whole x, therefore, x
5. No. You solve them like you would a normal equation with like terms. So it would be 3z^2

Hopefully these are right, I’m a bit rusty!
6. 4x
7. 3y
8. y - 4.5
9. 3.5x + 2
10. 4y + 2
11. 7x
12. 2.2w - 0.5
13. 23b + 6.6
14. 3.75x + 1.5
15. 0.8x + 2.1
Good luck, I hope this helped

G(a)=a-5 <br> h(a)=2a-4 <br> find g(h(1))
suter [353]

Calculate h(1):

h(a) = 2a - 4 → h(1) = 2(1) - 4 = 2 - 4 = -2

Next calculate g(-2):

g(a) = a - 5 → g(-2) = -2 - 5 = -7

<h3>Answer: g(h(1)) = -7</h3>

The perimeter of △MTV is 605 in.<br><br> MV = ?<br><br> m∠M = ?
swat32

Answer:

MV = 160 (and %50 sure) X = 27

Step-by-step explanation:

To find MV we just have to subtract the two lengths of the perimeter that we do know, minus the total perimeter, and find the difference. (using that its, 605-160-285 = 160) with that knowledge, we can say two things. MV = 160, and <V = <T by the two side lengths being congruent. With that, we can say that X + X +X+99 = 180, and then just find X, 27+27+27+99=180.

The relation R is shown below as a list of ordered
Dmitrij [34]

Answer:

(1, 4) and (1,3), because they have the same x-value

Step-by-step explanation:

For a relation to be regarded as a function, there should be no two y-values assigned to an x-value. However, two different x-values can have the same y-values.

In the relation given in the equation, the ordered pairs (1,4) and (1,3), prevent the relation from being a function because, two y-values were assigned to the same x-value. x = 1, is having y = 4, and 3 respectively.

Therefore, the relation is not a function anymore if both ordered pairs are included.

<em>The ordered pairs which make the relation not to be a function are: "(1, 4) and (1,3), because they have the same x-value".</em>
