Answer 1

Answer:

Apply the distributive property to the left-hand side of the inequality.

Step-by-step explanation:

Using PEMDAS, what you need to do first is clear!

P -> parentheses ( distribute, clear them out, etc. )

E -> exponents

M -> multiplication

D -> division

A -> addition

S -> subtraction

Going in order, you would apply the distributive property first to clear out the parentheses.

Answers

Answer:

y=-3x+7

Step-by-step explanation:

Rise/run

To find slope you can use the rise/run strategy. You count how many units up/down and then how many right/left. between each point on the line, it was down 3 units, right 1 unit (3/1) and since it was going down it would be negative.

As for the y-intercept, you look at where the line crosses the y-axis. In this case it was at (0,7), so the answer would be 7.

Plug your answers in and your equation should be y=-3+7.

You could also do y=7-3x, its the same equation but reversed, so you'll get the same line.

Hope this helps :)

Ok, so the answer is 3.5

Step-by-step explanation:

From what I could see it says walked for 14 around her block 4 times so your answer is 3.5 because if (Let's call her Patricia) Patricia walked around her block 4 times in 14 minutes, we have to find the unit rate, therefore we have to divide 14 by 4 as shown below

[tex]14/4=3.5[/tex]

Thus your only viable solution is 3.5

Answers

Answer:

Bonnie :

(0,12),(1,16)

Slope = (16 - 12) / (1 - 0) = 4/1 = 4

So Bonnie is adding $ 4 every week to her savings

Bobby :

y = 12x + 4

The slope here is 12.....so he is adding $ 12 every week to his savings

Therefore, the rate at which Bobbie is adding to his savings each week is (12 - 4) = $ 8 more then the rate at which Bonnie is adding to her savings account each week

Referring to the figure, find the surface area
of the pyramid shown. Round to the nearest whole number.

Answers

Answer:

297 is the surface area

Step-by-step explanation:

Ok this problem is very simple.

First lets define some equations.

Area of a triangle: A = 1/2BH

A = Area B = Base H = Height

This equation works for right triangles only.

(because 2 right triangles make a square which is why it's multiplied by 1/2 because it's half a square).

Area of a square: A = BH

Surface area equals all the areas of each side added together.

First lets find the area of one of the triangles.

We know 11 is the base and 8 is the height but the triangle isn't a right triangle.

To make it a right triangle divide the base by 2 so 11/2.

You will get 5.5.

Now find the area!

A = 1/2BH

A = 1/2(5.5)(8)

A = 1/2(44)

A = 22

So now we found the area of the right side as a right triangle but you must multiply it by 2 to get the entire side (because we divided the base by 2).

22(2)=A

44=A

44 is the area of one side of the pyramid but there are 3 other sides (not including the base).

So just do:

44+44+44+44 = A

176 = A

Surface area for the triangles is 176!

Now we must find the area of the square.

A = BH

A = 11(11)

A = 121

Total surface area is all the areas added together so it's:

121+176=A
