Substitue y=3x+2 to the y in y=x+10.
3x+2= x+10

Subtract 2 to both sides.
3x=x+8

Subtract x to both sides.
2x=8

Divide both sides by 2
2x/2 = 8/2

You are left with x = 4

Choose one equation and replace x by 4.
y = (4) + 10
y= 14

Now, you have x = 4 and y= 14. So, your ordered pair is (4,14) because both lines pass through that point.

If you do not want to do this solution, I suggest you graph it using the slope.

Find x round. your answer to the nearest tenth of a degree
Juli2301 [7.4K]

Answer:

x = 55.6

Step-by-step explanation:

Recall the 3 main trig functions

Sin = opposite / hypotenuse

Cos = adjacent / hypotenuse

Tan = opposite / adjacent

Note that hypotenuse = longest side length

We want to find angle "x".

We are given its opposite side length ( 19 ) as well as the adjacent side length

When dealing with the opposite and adjacent we use tan

Tan = Opp / Adj

Opp = 19 and Adj = 13

Tan(x) = 19/13

* take the inverse tan of both sides *

x = 55.6
