The Traingle XYZ and ACB are similar triangles. tanX = tanA = 5 over 2 and 5 tenths,

AC = 2 * XY; CB = 2 * YZ

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Triangle XYZ was dilated by a scale factor of 2 to create triangle ACB, hence XYZ and ACB are similar triangles.

Angles Y and C both measure 90 degrees, and angles A and X are congruent. Hence:

tanX = tanA = 5 over 2 and 5 tenths

AC = 2 * XY; CB = 2 * YZ

A number is x units to the right of 0 on a number line. What do you know about the opposite of the number?

Dmitry_Shevchenko [17]

Answer:

the opposite number is going to be negative because if x is to the right of the number line then the opposite will be of the left of 0 making the opposite number negative.

8x+3y= 28 and 7x-3y=2<br>solve for x and y simontaniasly using elimination

EleoNora [17]

Answer:

x=2, y=4

Step-by-step explanation:

When using elimination, the objective is to elimate one variable. In this case, we see that "y" can easily be eliminated by adding the two equations together since you will get 3y + (-3y) which will eliminate y because the value would become 0, letting us solve for x.

$\left \{ {{8x+3y=28} \atop {7x-3y=2}} \right. +\\$

Then we get

$15x =30$ , because the y's will eliminated, and 8x+7x is 15x, and 28+2 is 30.

Then divide by 15 on both sides and you get x=2

If x=2, then we can substitute that value into any of the previous given equations and find the value of y.

8×2 +3y = 28

16+3y=28

3y=12

y=4

So the answer to your system of equations would be x=2, and y=4

You can substitute the answers we found to see that they satisfy the equation.

Hope this helped.
