Answer:

See below

Step-by-step explanation:

y = 2x + 4     Substitute this for y in the second equation

6x - 3y = -12

6x - 3(2x + 4) = - 12  Substitute this for y for 2x + 4

6x - 3(2x) -3(4) = -  12    Distributive property

6x - 6x - 12 =  - 12

(6x - 6x) -12 = - 12   like terms together

 0 - 12 = - 12       Simplify

-12 = -12        True equation so x is equal to any number  and you have the same equation

Set up a proportion and soive for<br> side TV (y):<br> ATUV-AXWV
slega [8]

As we Know that, ΔTUV\sim ΔXWV

So, for the given proportion TV(y) = 21.

What is Proportion?

A proportion is an equation that sets two ratios at the same value. For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls. 0.25 are male (by dividing 1 by 4)

What is Ratio?

The link between two or more things in terms of quantity, amount, or size.

Given that,

ΔTUV\sim ΔXWV

∠T = ∠X

∠U = ∠W

∠TUV = ∠XWV

So, TU/WX = TV/WV

10/10 = TV/21

1 = TV/21

TV = 21

So, for the given proportion the value for the side TV(y) = 21
