Use a graph to find x and y values that make both y=-23x+3 and y=2x−5 true.

Answers

Answer:

y=x^2

Step-by-step explanation:

The graph of the equation y = - 23x + 3 and y = 2x - 5 is attached in the image below.

What is the graphical solution of a system of equations?

Graphical solutions of a system of equations are a way of finding the intersection points of all the equations given.

A system with two or more than two equations has a solution only when they have a common intersection point.

Given, Are two equations y = - 23x + 3 and y = 2x - 5.

Subtracting equation 1 from equation 2 we have,

25x = - 8.

x = - 8/25.

y = - 2(8/25) - 5.

y = - 16/25 - 5.

y = (- 16 - 125)/25.

y = - 141/25.

Meghan earns $20 for every 5 bracelets she makes. How many bracelets must she make to earn $140?

Answers

So this is a two step equation.
The first step would be to find out how many times 20 goes into 140.
140/20=8
So if she makes 5 bracelets for every 20 dollars she makes, and she made 20 dollars 8 time. She would’ve made 5 bracelets, 8 times.
So take 5 bracelets and multiply it by 8.
She needs to make 40 bracelets. :)
Meghan made 35 bracelets

The dimensions of a rectangular prism are shown below:

Length: 1 and 1 over 2feet
Width: 1 foot
Height: 2 and 1 over 2feet
The lengths of the sides of a small cube are 1 over 2 foot each.

Part A: How many small cubes can be packed in the rectangular prism? Show your work. (5 points)

Part B: Use the answer obtained in part A to find the volume of the rectangular prism in terms of the small cube and a unit cube. (5 points)

Answers

Answer:

Step-by-step explanation:                    

A - 30 cubes

B - Volume of prism = feet³

Step-by-step explanation:

We are given that the dimensions of the rectangualr prism is,

Length = = feet

Width = 1 foot

Height =

feet

Thus, the volume of the prism = Length × Width × Height

i.e. Volume of the prism =

feet³

Now, the side of the cube =

foot each.

Volume of the cube =

feet³

Part A: Number of cubes which can be packed inside the prism are given by,

Number of cubes = Volume of prism divided by Volume of cube

i.e. Number of cubes =

  i.e. Number of cubes =

 i.e. Number of cubes = 15 × 2 = 30

Hence, 30 cubes can be packed inside the rectangular prism.

Part B: As we have, there are 30 cubes which can be fit inside the prism.

Since, the volume of 1 cube =

feet³  So, Volume of 30 cube =

=

feet³

Thus, the volume of the rectangular prism is

feet³

Step-by-step explanation:

Answer:

Step-by-step explanation:

We notice that every time one the number increases, it increases by 3.  To find it, first we subtract 4.5 and 3 to get 1.5 and this point is going to be (2, 1.5) Now, to find the cost of 1, we have to subtract 3 again to get (1, -1.5)

- 1/2 - 2/3v = 4/5 please help

Answers

Answer:

-39/20 (decimal is -1.95)

Step-by-step explanation:

First, you have to isolate the variable term (-2/3v). You can do this by moving -1/2 to the other side. Then, the right side would be 4/5+1/2. Make this side common by changing the denominators to being the same thing (8/10+5/10=13/10). Now, we know that 13/10 is equal to -2/3v. You can then divide both sides by -2/3 to get v. If you're lazy like me, just use a calculator to divide 13/10 by -2/3. What you get then is your answer!

Hope this helps! Please mark me as brainliest!

Answer:

v = - 39/20

Step-by-step explanation:

-1/2 - 2/3v = 4/5

-2/3v= 4/5 + 1/2

-2/3v = 8/10 + 5/10

-2/3v = 13/10

v = 13/10 * -3/2

v = - 39/20

B) Alana needs 4 ½ more cups of sugar

C) Alana needs 5 more cup of sugar

Answers

Answer:

Question1)d question2)B

Answer:

Question 1) D The temperature dropped 4 degrees each hour for 5 consecutive days.

Question 2) B Alana needs 4 1/2 more cups of sugar.

Step-by-step explanation:

Question 1) Since the 4 is negative, this means that something needs to be decreasing. The temperature is the only example in which this is the case.

Question 2) If one pumpkin pie calls for 1 1/4 cups of sugar, four pumpkin pies calls for 5 cups of sugar: 4*1 1/4. Since Alana already has 1/2 cup of sugar, 5-1/2=4 1/2.
