Answer:

Both lines intersects at (3, 1)

given:

y = -2x + 7

y = 5x - 14

solve them simultaneously:

-2x + 7 = 5x - 14

5x + 2x = + 7 + 14

7x = 21

x = 3

solve for y:

y = -2x + 7

y = -2(3) + 7

y = -6 + 7

y = 1

Gemiola [76]

Step-by-step explanation:

step 1. what is the question? maybe the question is what is the value of x in the diagram. okay.

step 2. interior angles of a triangle add up to 180°

step 3. the 3 angles inside the triangle are 10x + 8, 13 + 5x, and (180 - 126)

step 4. (10x + 8) + (13 + 5x) + 54 = 180

step 5. 15x + 21 = 126

step 6. 15x = 105

step 7. x = 7.

What is the measure of x?

Sveta_85 [38]

Answer:

Hello!

After reviewing the problem you have provided I have come up with the correct solution:

x= 9

Step-by-step explanation:

To come up with this solution you have to first realize that the smaller triangle is a proportionally scaled down version of the entire larger triangle! (I will show what I mean in a linked picture)

So after we have realized that the smaller triangle is a scaled down version of the larger one, we can then create a formula or ratio to calculate the value of the missing side of the larger triangle (being x+6=??).

To create the formula/ratio I divided 10inches by 4inches. Thus the larger triangle is 2.5 times larger than the smaller one.

I then use this ratio to figure out the missing length of the larger triangle by doing:

6inches x 2.5 = 15inches.

I then inputed the 15inches into the formula of the missing side:

x+6=15

Subtracted 6 from both sides to simplify, and came up with the solution!

x=9

Let me know if this helps!
