x + y = -10 in slope intercept form

Answers

Step-by-step explanation:

Hey there!

Given;

x+y= -10

We know that slope intercept equation form of straight line is; y = mx+c.

So, let's try to convert it into that form.

Shift"X" in Right side.

y = -x-10

Therefore, y = -x-10.

Hope it helps..

I need help with angles

Answers

Answer:

The value of x is 8

The measure of angle A is 42 degrees

A and B are consecutive interior angles

Step-by-step explanation:

Since A and B are consecutive interior angles you combine both equations and have it equal to 180

16x+10+5x+2=180

21x+12=180

21x=168

x=8

Plug 8 into the equation across from A

16(8) +10

128+10

138 degrees

Since angle A is supplementary you do 180-138= 42 degrees

If f(x) = x2 + 4x + 9. find f(-2)

Answers

Answer: f (-2) 5

Your welcome

A function is a relation between two variables where one variable is the set of inputs that gives the other variables as output.

The value of the function at x = -2 is 5.

The domain of the function = 5.

The range of the function = -2.

What is a function?

A function is a relation between a set of inputs called domains and it has one output called the range.

Example:

f(x) = x + 2

At x = 2,

f(2) = 2 + 2 = 4

Domain = 2

Range = 4

We have,

f(x) = x² + 4x + 9

We need to find the value of the function at x = -2.

Substitute x = -2 in f(x).

f (-2) = (-2)² + 4x(-2) + 9

f (-2) = 4 - 8 + 9

f (-2) = 5

Thus the value of the function at x = -2 is 5.

Answer:

Step-by-step explanation:

We can use scale factors to represent the lengths. Since the flagpole's base is 4 times the tree's height, we can also say that the flagpole's height is 4 times the tree's height. Since the tree's height is 5 feet, the flagpole's height is 4 x 5, which is 20.

Pls consider giving my answer Brainliest! It would mean and help a lot! ; )

Answer:

5:2

Step-by-step explanation:

The answer is 5:2 because:

1) Since there are 2 male teachers for every 5 female teachers, the ratio has to be 5:2 because they did not give us any specific numbers.

For example, if they 10 female teachers, then there would be 4 male teachers. The ratio for this example would be 10:4

Mai and Jada are both running on a treadmill. Mai travels 5 miles in 15 minutes. Jada travels 4 miles in 14 minutes. Who ran at a faster rate? Show and explain your reasoning

Answers

Answer:

Mai

Step-by-step explanation:

To find the rate, you must determine who is going faster per minute. To do this, you must divide the total number of miles by the total number of minutes.

Mai: 5 miles / 15 minutes = 1/3 miles per minute

Jada: 4 miles / 14 minutes = 2/7 miles per minute

Then, use a common denominator to make calculations easier:

Mai: 1/3 * 7/7

Jada: 2/7 * 3/3

You should get:

Mai: 7/21 miles per minute

Jada: 6/21 miles per minute

By looking at this, you can see that Mai is traveling slightly faster, going more miles than Jada per minute.

What are the slope and the y-intercept of the linear function that is represented by the equation Y=-10x+1?

a. The slope is -10, and the y-intercept is -1.
b. The slope is -10, and the y-intercept is 1.
c. The slope is -1, and the y-intercept is -10.
d. The slope is 1, and the y-intercept is -10.

Answers

Answer:

b. The slope is -10, and the y-intercept is 1.

Step-by-step explanation:

Y = slope(x) + y-intercept

Answer: B) slope = -10, y intercept = 1

The general form is y = mx+b

m = slope

b = y intercept

Comparing y = -10x+1 to y = mx+b we see that

m = -10

b = 1

Write a paragraph proof for the following conjecture:
Given: m∠1 +m∠2=m∠4
Prove: m∠3 +m∠1 +m∠2=180°

Answers

Answer:

The answer to your question is given below.

Step-by-step explanation:

From the question given,

m∠1 + m∠2 = m∠4

To prove that:

m∠3 + m∠1 + m∠2 = 180°

We simply do the following:

m∠3 + m∠4 = 180°.... (1) (angle on a straight line)

But from the question given,

m∠4 = m∠1 + m∠2

Substitute the value of m∠4 into equation (1)

m∠3 + m∠4 = 180°

m∠3 + m∠1 + m∠2 = 180° QED
