Find the slope of the line through the given points. (1,3) and (0,−9)

Thank you so much :)

Answers

Answer:

The answer is 12

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(1,3) and (0,−9)

The slope is

[tex]m = \frac{ - 9 - 3}{0 - 1} = \frac{ - 12}{ - 1} = 12 \\ [/tex]

We have the final answer as

12

Hope this helps you

The slope of the line would be 12.

They will break even... but im not 100% sure im correct

Step-by-step explanation:

Im not 100% sure but here is what i have...

based on the given inequality the new one would be 15n>105+4.50n,

First subtract the 4.50n from the right side of the inequlaity sign.

Now you should have 10.5n>105

second, plug in a random number to see if she will make money or not..

I used 10, so plug 10 in for "N".

it will look like this, 10.5(10)>105

now do the math and get, 105>105,

which brings me to the cunclution she breaks even..

Angle Z is 21 degrees larger than twice the measure of angle T. If ∠Z and ∠T are supplementary, what is the measure of angle T? *

Answers

angle T = x

angle Z = 2x + 21

We know that supplementary angles add up to 180 degrees.

180 = x + 2x + 21

Combine like terms.

180 = 3x + 21

Subtract 21 from both sides.

159 = 3x

Divide both sides by 3

53 = x

angle T = 53 degrees

What is inequality?

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

Anna has a nickels and y dimes. She has at most 22 coins worth a minimum of $1.40 combined.

Let x be the number of nickels and y be the number of dimes. Then the equation is given as,

0.05x + 0.10y ≥ 1.40

x + y ≤ 22

The system of the inequalities will be 0.05x + 0.10y ≥ 1.40 and x + y ≤ 22. And the graph is given below.
