Step-by-step explanation:

The image is an example of a linear equation that is both a function and positive lenear

Answer:

To figure out if an ordered pair is a solution to an equation, you could perform a test. Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation.

D. AC/GI = BC/HI

Step-by-step explanation:

Angles that are congruent don't necessarily mean they're similar. But this is what I saw that is associated with similarity with triangles.

AC and GI are corresponding sides and BC and HI are corresponding sides as well so, yeah. D.

I think.

I guess.

I don't know.

I didn't pay attention, tbh. LOL

~Pengoon~

To prove that the triangles are similar based on the SAS similarity theorem, it needs to be shown that: AC/GI = BC/HI.

The properties of similar triangles.

In Geometry, two (2) triangles are said to be similar when the ratio of their corresponding side lengths are equal and their corresponding angles are congruent.

Based on the side, angle, side (SAS) similarity theorem, it needs to be shown that side AC/GI is equal to side BC/HI in order to prove that the triangles are similar.

Proof:

AC/GI = BC/HI

15/9 = 20/12

5/3 = 5/3.

From left to right, -3/2, -4/5, -3/10, 1/2, 7/8, 4/3

Step-by-step explanation

So what we're trying to do here is to order the numbers from greatest to least.

Let's start off with the negative numbers.

-3/10, -4/5, -3/2.

Now what we want to do is give them all a common denominator to figure out which one is the least of that group.

-3/10,-8/10,-15/10.

Now on to the positive numbers.

1/2, 4/3, 7/8

Turn the denominator into 24.

12/24, 32/24, 21/24

Then put them all in order.

What value of x makes the equation true

Answers

Answer:

A

Step-by-step explanation:

The equation in simple terms is 3x+2=-2x+6. This is because there are 3 triangles with x in them and 2 squares with 1 in them on the left side, and 2 triangles with -x on the right side with 6 1's. If you don't know how to solve this I'd be happy to go in full depth: subtract 2 from 6, subtract -2x from 3x this will give you 5x=4 and then you divide 5 from for giving you 4/5 or 0.8.
