Write a list of steps that are needed to find the measure of ∠B.

Answers

9514 1404 393

Answer:

  ∠B = 41°

Step-by-step explanation:

Step 1: Recognize that ∠B and ∠A are "remote interior angles" with respect to the exterior angle at C. Hence their sum will be equal to the measure of the exterior angle.

Step 2. Compute angle B as the difference between the exterior angle at C and the interior angle at A:

  113° - 72° = ∠B = 41°

True or False: (1, 3) is a solution to the system of linear equations shown

y= 4x - 1
y = x + 2

Answers

Answer:

True

Step-by-step explanation:

(1, 3) is a solution to the system of linear equations shown is true

Answer:

True

Step-by-step explanation:

You can substitute x = 1 and y = 3 into both equations and see if it's true or not.

y = 4x - 1

becomes

3 = 4(1) - 1

3 = 4 - 1

3 = 3

True

y = x + 2

becomes

3 = 1 + 2

3 = 3

True

Since both equations come out true, this (1, 3) is a solution.

Which graph represents a linear function?

Answers

Answer:

Please check the explanation below.

Step-by-step explanation:

Note: As you forgot to mention the graphs of a linear function. But, let me clear your concept with an example of a linear function.

We know that linear function is of the form

y = mx+b

where

m is the slopeb is the y-intercept

We know that the graph of a linear function is a straight line because the highest power of the exponent of the x variable is 1.

Thus, y = mx+b represents a straight line.

For example,

Let the linear function

y = 2x+3

comparing with the linear function of the form y = mx+b

The slope = m = 2The y-intercept b = 3

As the highest power of the exponent of a variable is 1, therefore y = 2x+3 represents a straight line.

The graph of the linear function y = 2x+3 is also attached below.

ahhh please help i don’t understand thissss

Answers

Answer:

24y^3/x^5

Step-by-step explanation:

Since 6x and 4x are not in a parentheses, they are not being powered by anything. Therefore, those stay on the numerator side.

Anything to the power of something times another to the power of something is always added together. Since -1 + (-4) is -5, x would end up having a power of -5, which would just make it go on the denominator side with just a power of 5.

Same rule with y follows. This would make it 5+ (-2) = 3. Since this is a positive power, it stays at the numerator side.

Answer:  b. negative

=======================================================

Explanation:

Each time x goes up, y goes down. This inverse relationship means we have a negative slope.

----------

We can apply the slope formula to get further proof.

Let's say we pick the first two columns to form the points (1,24) and (2,18)

Then apply the slope formula to get...

m = (y2-y1)/(x2-x1)

m = (18-24)/(2-1)

m = -6/1

m = -6

The slope is -6.
