plz be speed ill give brainliest

Answers

Answer:

y = -1/13x + 1 3/13

Step-by-step explanation:

y = 13x + 2

Perpendicular

y = -1/13x + b

Finding b:

1 = -1/13 * 3 + b

1 = -3/13 + b

1 3/13 = b

y = -1/13x + 1 3/13

Please let me know if I'm wrong :)

the answer is y=-3x+10

What is the minimum angle of rotation (in degrees) that will carry the star onto itself?

Answers

Answer:

When you rotate the regular pentagon \begin{align*}72^\circ\end{align*} about its center, it will look exactly the same. This is because the regular pentagon has rotation symmetry, and \begin{align*}72^\circ\end{align*} is the minimum number of degrees you can rotate the pentagon in order to carry it onto itself.

Step-by-step explanation:

\begin{align*}72^\circ\end{align*} is the minimum number of degrees

Amelia is building 3 square garden beds that are all the same size. She arranges them side-by-side to seperate the certain plants. Amelia wants to know the total area of the garden beds.

s= length (ft) of one side of a garden bed.
there are three garden beds. they are squares.
Write an expression to show the total area of garden beds.

Answers

Answer:

3(s x s)

Step-by-step explanation:

You can find the area of each garden bed by multiplying the length of each square, and since a square has four equal sides, the area of one square would be s times s. S times s equals the area of ONE square, so you would take that area and multiply it by three, since you have three squares. Hope this helps!

Answer:

3(s x s) or 3s^2

Step-by-step explanation:

The formula for area is l x w or length x width. The length and width in this case would be "s" and "s." The variable is "s" because "s" can be any number. There are 3 square garden beds so we have to multiply the s x s equation by 3 which would get us to 3 x s x s.

Tom is buying a package of pens at a store. The store sells packages of 8 pens for $1.28 and 14 pens for $1.54. Which package offers the better unit price? Question 4 options: A. 8 pens for $1.28

plzz help me A.S.A.P!!!

Answers

Answer:

14 pens for $1.54

Step-by-step explanation:

If you divide $1.28 by 8, you get $0.16. If you divide $1.54 by 14, you get $0.11, therefore the 14 pen package is a better deal.

Answer:

It would be 14 pens for $1.54

Step-by-step explanation:

Divide 1.28 and 8, you get 0.16

Divide 1.54 and 12, you get 0.11

The 14 pens offers a better unit price of .11 cents per pen, instead of .16 cents per pen.

On Monday, Elsbeth’s bank account balance was -$16.75. On Tuesday, she deposited a check for $5.72. On Thursday, she deposited $16.75. What is her new balance?

-16.75 + (5.72 + 16.75)

Use the commutative property to get:

-16.75 + (16.75 + 5.72)

Use the associative property to get:

(-16.75 + 16.75) + 5.72

On Friday, Elsbeth deposited her pay check for $872.56. What was the account’s final total?

Answers

Answer:

$5.72

Step-by-step explanation:

The easiest way to do this is take the two deposits and add them together then combine with the original balance.

Add 5.72 and 16.75

5.72+16.75=22.47

Then subtract -16.75 from 22.47

22.47-16.75=5.72

The answer is 22.47
