Answer 1

Answer:

4 * 2y + 4 * 1

4(2y + 1)

Distributive property

Step-by-step explanation:

8y + 4

We can factor out a 4 out of both as both are divisible by 4

8y / 4 = 2y

4 / 4 = 1

So 8y + 4 is the same as saying 4 * 2y + 4 * 1

This can be written as 4(2y + 1) which is written using the distributive property

Answer:

[tex]x = 2.4[/tex]

Step-by-step explanation:

Step 1: Find the length of AB

[tex]\frac{ED}{EA} = \frac{EC}{EB}[/tex]

[tex]\frac{15}{12} = \frac{18}{12+x}[/tex]

Cross Multiply

What is the y-intercept, end behavior and zeros of this polynomial function?

g(x) = (x + 2)(x − 1)(x − 2).

Describe the direction of the parabola and determine the zeros and y-intercept.

f(x) = (x – 3)(x – 2).

WILL MARK BRAINLIEST IF BOTH ANSWERS ARE CORRECT

Answers

Answer:

To determine its end behavior, look at the leading term of the polynomial function. Because the power of the leading term is the highest, that term will grow significantly faster than the other terms as x gets very large or very small, so its behavior will dominate the graph.

Step-by-step explanation:

Graph the line that represents a proportional relationship between ddd and ttt with the property that an increase of 3 units in ttt corresponds to an increase of 8 units in ddd.
What is the unit rate of change of ddd with respect to ttt? (That is, a change of 1 unit in t will correspond to a change of how many units in d?)

Answers

The unit rate of change of d with respect to t is 8/3

How to graph the line?

The statement is given as:

increase of 3 units in t corresponds to an increase of 8 units in d.

This can be represented using the following ratio

t : d = 3 : 8

Express as fraction

t/d = 3/8

See attachment for the graph of t/d = 3/8

The unit rate

In (a), we have:

t/d = 3/8

Inverse both sides

d/t = 8/3

This means that:

Slope or Rate = 8/3

Hence, the unit rate of change of d with respect to t is 8/3

Perry saved 4 twenty-dollar bills, 2 ten-dollar bills, 3 dimes, and 2 pennies. Before winter break, he bought a new racing video game for $49.86. How much money did Perry have left?

Answers

Answer:

[see answer below]

Step-by-step explanation:

"Perry saved 4 twenty-dollar bills, 2 ten-dollar bills, 3 dimes, and 2 pennies."

4 * 20 = 80

2 * 10 = 20

3 * 0.1 = 0.3

2 * 0.01 = 0.02

80 + 20 + 0.3 + 0.02 = $100.32

100.32 - 49.86 = 50.46

Step-by-step explanation:

Tuition - (room and board)

Distribute the minus sign

8x+3 = (x) =12 because if 8x + 75 means that x alone will still be 8 the x + 3 +5 =16

There are two types of tickets sold at the Canadian Formula One Grand Prix race. The price of 5 grandstand tickets and 3 general admission tickets is 2490. The price of 6 grandstand tickets and 6 general admission tickets is 3540 . What is the price of each type of ticket?

Answers

General admission tickets are $287.50 each and grandstand tickets are $311.25 each

Answer: Grandstand: 360, General Admission: 230

Step-by-step explanation:

Use any variable you like but:

Let g represent grandstand ticketsLet a represent general admission tickets

You know:

5 Grandstand tickets and 3 general admission tickets is 2490:

5g + 3a = 2490

The price of 6 grandstand (g) tickets and 6 general admission tickets (a) is 3540

6g + 6a = 3540

You want to find out: What is the price of each ticket. To do this either use substitution or elimination.

I will demonstrate elimination:

To do elimination, you want to cancel out one variable. This means you want to multiply each side of the equation by a number. I see 3a and 6a. This means multiply by -2. Again, you want to eliminate the variable.

5g +3a = 2490 → -10g - 6a = -4980

Now, add the two equations together: Notice how you can line them up vertically to see how they can add together.

-10g - 6a = -4980+6g + 6a = 3540After that step you get: -4g = -1440

Now you can solve for the g (grandstand tickets):

-4g = -1440g = 360

You now know grand stand tickets cost 360. Take one of your original equations and solve for a (general admission tickets). To double check your work, they should satisfy both equations.

5g + 3a = 24905(360) + 3a = 24903a = 690a = 2306g +6a = 35406(360) +6a = 35406a = 1380a = 230

Therefore general admission tickets cost 230, and grandstand tickets cost 360!

A law in Washington, D.C., restricts a new building's height to no more than 20 feet taller than the width of the street it faces. You design a building with stories that are each 15 feet tall for a street that is 88 2/3 feet wide. What is the greatest number of stories your building can have?

_______ Stories

How much shorter is your building than the height restriction?

________Feet

Answers

It can be up to 20 feet taller so add 20

To the width:

88 2/3 + 20 = 108 2/3

Divide total height by the height of one story:

108 2/3 / 15 = 7.24

The building can have 7 stories.

b. 7 x 15 = 105 total feet

108 2/3 -105 = 3 2/3 feet below the restrictions
