Answer:

Step-by-step explanation:

1). Slope of a line shown on the graph will be,

   Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

              = [tex]\frac{-4}{1}[/tex]

              = -4

2). Slope of the given horizontal line can be determined by,

    Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

    Since, rise of the given line is zero.

    Therefore, slope of the given horizontal line will be 0.

3). Slope of the line passing through the indicated line = -2

    Therefore, a line which has a rise = -2 and run = 1 can be drawn on the given blank grid (As attached).

Answer:

Step-by-step explanation:

1. -4. Explanations vary. Sample explanation: for each horizontal change of 1, the vertical change is -4, so the slope of the line is -4.

2. 0. Responses vary. Sample response: The amount of rainfall on a day with no rain.

3. A graph through the indicated point with a slope of -2.

Substituting u = 6x - 5, you write

y = cos(u)

Then differentiating with the chain rule gives

dy/dx = dy/du • du/dx

We have

dy/du = -sin(u)

du/dx = 6

so

dy/dx = -6 sin(u) = -6 sin(6x - 5)

Answer:

3 batches of cookies

Step-by-step explanation:

Bank. A recipe for one batch of cookies calls for 5 cups of flour and 2 teaspoons of vanilla.

How many batches can you make with 15 cups of flour and 6 teaspoons of vanilla?

We can calculate the batches using either cups of flour or number of teaspoons.

For flour

5 cups of flour = 1 batch of cookies

15 cups of flour = x

Cross Multiply

5x = 15 × 1

x = 15/5

x = 3 batches of cookies

For teaspoons of vanilla

2 teaspoons of vanilla = 1 batch of cookies

6 teaspoons of vanilla = x

Cross Multiply

2x = 6 × 1

x = 6/2

x = 3 batches of cookies.

Hence: you can make 3 batches of cookies with 15 cups of flour and 6 teaspoons of vanilla

I believe it's negative thirty six or -36

Answer:

-1/2 and -1

Step-by-step explanation:

Our system of equations is:

y = 2x²

y = -3x - 1

We can set the y's equal to each other:

y = 2x² = -3x - 1

Now, we have:

2x² = -3x - 1

Move all the terms to one side by adding both sides by 3x and 1:

2x² + 3x + 1 = 0

We must factor this quadratic. Note that the factoring is:

(2x + 1)(x + 1) = 0

Our solutions are now:

2x + 1 = 0           OR           x + 1 = 0

x = -1/2                                x = -1

.

Thus, our solutions are -1/2 and -1.

Answer:  B. $15.68

Step-by-step explanation:

Given: Selling price of album = $16.00

Discount = 10% off

Sales tax = 8%

Discount = 10% of ( Selling price of album)

= 10% of $16

= 0.1 ($16)

= $1.6

Sales tax = 8% of ( Selling price of album)

= 8% of $16

= 0.08 ($16)

= $ 1.28

Total price of the album including tax = Selling price of album +Sales tax  - Discount

= $ 16 + $1.28 - $1.6

= $ 15.68

Hence, B. is the correct option.

Step-by-step explanation:

Answer:

c = 80:)

Step-by-step explanation:

Divide John's goal amount by his hourly rate to find the answer.

$600 ÷ $7.50/hour = 80 hours.

So, John will have to work a total of 80 hours in order to earn $600.

Answer:

80

Step-by-step explanation:

If you divide 600 with 7.50 you will get 80.

That is simple!

Find the GCD (or HCF) of numerator and denominator

GCD of 600 and 750 is 150

Divide both the numerator and denominator by the GCD

600 ÷ 150

750 ÷ 150

Reduced fraction:

4

5

Therefore, 600/750 simplified to lowest terms is 4/5.

Answer:

The difference is that in the first equations you multiply the 10 by 4 first because of PEMDAS rule. But in the second equation you add the 4 and 5 before multiplying. Thats the only difference :D

Answer:

He throws 7 passes

Step-by-step explanation:

say he throws x more completed passes.

62.5% = 5/8. So, counting up all the completions, we must have

18 + x = 5/8 (33+x)

He total completes:

18 passes during the first three quarters and x passes

during the fourth quarter = 18 + x passe

He total make:

33 throws during the first three quarters and x throws

during the first the fourth quarter = 33 + x

62.5 % = 62.5 / 100 = 0.625

Proportion is:

( 18 + x ) / ( 33 + x ) = 0.625

Multiply both sides by 33 + x

18 + x = ( 33 + x ) ∙ 0.625

18 + x = 33 ∙ 0.625 + x ∙ 0.625

18 + x = 20.625 + 0.625 x

Subtract 18 to both sides

18 + x - 18 = 20.625 + 0.625 x - 18

x = 2.625 + 0.625 x

Subtract 0.625 x to both sides

x - 0.625 x = 2.625 + 0.625 x - 0.625

0.375 x = 2.625

Divide both sides by 0.375

x = 2.625 / 0.375 = 7

In the fourth quarter throw 7 passes.

Proof:

( 18 + 7 ) / ( 33 + 7 ) = 25 / 40 = 0.625 = 62.5 %

There are 7 passes does the quarterback throw in the fourth quarter.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

A quarterback completes 18 of 33 passes during the first three quarters of a football game.

And,  He completes every pass in the fourth quarter and 62.5% of his passes for the entire game.

Now,

By the given condition, we get;

Let x passes during the fourth quarters.

Hence, The total completes for 18 passes during first quarter = 18 + x

And, The total completes for 33 passes during first quarter = 33 + x

And,  He completes every pass in the fourth quarter and 62.5% of his passes for the entire game.

So, 62.5% = 62.5 / 100

                = 0.625

Thus, We get by proportions;

⇒ (18 + x) / (33 + x) = 0.625

Solve for x as;

⇒ (18 + x) / (33 + x) = 0.625

⇒ (18 + x) = (33 + x) × 0.625

⇒ 18 + x = 20.625 + 0.625x

⇒ x - 0.625x = 20.625 - 18

⇒ 0.375x = 2.625

⇒ x = 2.625 / 0.375

⇒ x = 7

Thus, There are 7 passes does the quarterback throw in the fourth quarter.

Answer:

361 and 362

Step-by-step explanation:

a+b=723

b-a=1

b=1+a

a+1+a=723

2a+1=723

2a=723+1

2a=724

a=362

362+b=723

b=723-362

b=361

so b and a are 361 and 362 respectively

hence the consecutive numbers are 361 and 362

$15.12

Step-by-step explanation:

{10 * 0.08 = 0.8

4 * 0.08 = 0.32} (Brackets are here so you can see what I did easier and so you could see how to do it mentally.)

[0.8 + 0.32 = 1.12]

14 + 1.12 = 15.12

David is buying a cheese wheel priced at $14 on 8% sales tax.

David's pays for the cheese wheel is $15.12 .

Given:

Before-tax, the price of cheese wheel = $ 14

Sales tax on cheese wheel = 8%

Sales tax is 8% of $14

[tex]=\frac{8(14)}{100} = \frac{112}{100} = 1.12[/tex]

So, the sales tax on the cheese wheel is $1.12

The total price of the cheese wheel, including tax = $ 14 +  $1.12 = $15.12

Therefore, David's pays for the cheese wheel is $15.12 .
