If triangle ABC is congruent to triangle DEF, the angles A and D are corresponding, angles B and E are corresponding, and angles C and F are corresponding. They are congruent as well. Since the only measures we have for corresponding angles is angle B and E. Since they are congruent, we can set them equal to each other to solve for x:
3x + 8 = 4x - 7 and x = 15. We can't use A and D because we don't have a value for A to set equal to D.

Is -0.3 a rational number? is 3.14144144414444... a rational number?

Ainat [17]

I will try to make this as simple as possible.

First off, we need to know what a rational number is: A rational number is any number that can be made by dividing 2 integers. For example:

1.5 would be a rational number because 1.5 = 3/2 (3 and 2 are both integers)

With that being said, let's begin.

First off, let's start with -0.3, let's ask ourselves, can we make this number by dividing 2 integers, the answer is yes, we can, by doing $\frac{-3}{10}$ we have the equivalent of -0.3, so now we know it's a rational number.

As for the second one, it can't be a rational number because it can't be made by dividing to integers, so the answer is:

-0.3 is a rational number, but 3.14144144414444 is not.

Hope this helped! c:

The function f(x) is shown in the graph.

anzhelika [568]

The function that describes the graph is an exponential function

<h3>How to determine the function type?</h3>

From the graph, we have the following highlights:

Initially, when x increases; y seem not to increase
Then, x and y increase at the same time
Finally, y increase and x seem not to increase

The above is the description of an exponential function

Hence, the function that describes the graph is an exponential function

50+ POINTS I NEED HELP

olga nikolaevna [1]

Answer:

21 yard line

Step-by-step explanation:

Ok we start out on the 20 yard line, we need to add the yards together.

We add the 6 to the 20:

20+6=26

Then we subtract the 8 yards from our new 26:

26-8=18

Then we add the 18 by 3:

18+3=21

Therefore,
