Answer:

13 y^2 - 13 y + 11

Step-by-step explanation:

Simplify the following:

15 y^2 - 2 y^2 + 2 y - 15 y + 4 + 7

Grouping like terms, 15 y^2 - 2 y^2 + 2 y - 15 y + 4 + 7 = (15 y^2 - 2 y^2) + (-15 y + 2 y) + (7 + 4):

(15 y^2 - 2 y^2) + (-15 y + 2 y) + (7 + 4)

15 y^2 - 2 y^2 = 13 y^2:

13 y^2 + (-15 y + 2 y) + (7 + 4)

2 y - 15 y = -13 y:

13 y^2 + -13 y + (7 + 4)

7 + 4 = 11:

Answer: 13 y^2 - 13 y + 11

Answer:

(14, 5)

Step-by-step explanation:

1. substitute- (x,y)=the original coordinates (9,9) right?

2. So no you want to do x, you have 9 and if you are moving right 5 units it'll be 9+5 because x is left to right on a graph.

9+5=14 therefore (14,y)

3. Now you do y, y is up and down. So you want to go down 4, you subtract 4 from 9 giving you five. Now you have (14,5)

Hope I could help! :)

Answer:

a = 0

Step-by-step explanation:

a + 5 = -5a + 5      subtract 5 from both sides

a + 5 - 5 = -5a + 5 - 5

a = -5a                add 5a to both sides

a + 5a = -5a + 5a

6a = 0                 divide both sides by 6

6a / 6  =  0 / 6

therefore,

a = 0

Step-by-step explanation:

There are 14 days in 2 weeks  ( 7 days in  1 week )

20 pages a day * 14 days = 280 pages

Answer: David reads 280 pages altogether.

Step-by-step explanation: If David reads 20 pages a day, and there are 7 days in a week, then he will read 140 pages in one week (20 x 7). Since the problem asks for how many pages he read in two weeks, then you can multiply 140 by 2 and get 280, which is your answer. Hope this helped :)

Answer:

1). Rational

2). Irrational

3). Rational

4). Rational

5). Irrational

Step-by-step explanation:

To solve this question we should follow the rule,

"Addition of rational and an irrational number is an irrational number."

1). [tex]\sqrt{16}=4[/tex] (rational number)

   [tex]-\frac{21}{5}[/tex] (negative rational number)

   [tex]\sqrt{16}-\frac{21}{5}=4-\frac{21}{5}[/tex]

                  [tex]=-\frac{1}{5}[/tex] [rational number]

2). π → (Irrational number)

   24 → (rational number)

   π + 24 → (Irrational number)

   Since addition of a rational and an irrational number is an irrational number.

3). [tex]\sqrt{4}[/tex] = 2 (rational number)

     5 (rational number)

    2 + 5 = 7 (rational number)

4). [tex]\sqrt{36}=6[/tex] (rational number)

   [tex]\sqrt[3]{27}=3[/tex] (rational number)

    [tex]\sqrt{36}+\sqrt[3]{27}=9[/tex] (rational number)

5). [tex]\frac{3}{4}[/tex] (rational number)

   [tex]\sqrt{27}[/tex] → (Irrational number)    

   [tex]\frac{3}{4}+\sqrt{27}[/tex] → (Irrational number)

Answer:

p = -2, r = -2 and p-r =  0.

Step-by-step explanation:

(x - 1/2)(x - 2)

= x^2 - 2x - 1/2x + 1

= x^2 - 5/2x + 1

= 2x^2 - 5x + 2

= -2x^2 + 5x - 2

Comparing this with

px^2 + 5x + r

we see that  p = -2, r = -2 and p-r =  0.

-25 + 15 = -10

1 - 13 = -12

-1 divided by 5 = -1/5

-5 multiplied by -1/5 = 1

The bold ones are the answers

Answer:

Step-by-step explanation:

1) n+15=10

     solution;

n+15= -10

so, n= -10 -15

      n= -25

2) n-13= -12

        solution;

remember the rule i told you in number 1 that's the same rule we will use here

n= -12+ 13

n=1

you see so easy... lets continue

3) n\5= -1\5

now in this one there is a new rule which is; when you see two fractions and there is an equal two in between them you cross multiply... okay lets solve

n\5= -1\5

-1*5=n*5

the reason why i exchanged was because the unknown should always be at the left hand side....okay

n*5=-1*5

5n/5= -5/5

5 will divide 5 which is remaining n

5 divide 5 which is -1

so n = -1

4) -5n =1

 this is not a fraction so we just take the -5 to 1 and no cross multiplication (they are whole numbers so they meet each other)okay...

so, n=1/-5

Step-by-step explanation:

Savannah had 400 chocolate chips. She saved x chips for a garnish, and mixed the rest of the chocolate chips evenly into 3 pans of brownies. Write your answer as an expression

Solution

Total chocolate chips Savannah has=400

Saved chips for garnish =x

Total chocolate chips remaining= 400 - x

We subtract the saved chocolate chips because when an item is saved, it will be deducted from the original Quantity

She mixed the rest of the chocolate chips evenly into 3 pans of brownies

That is,

Remaining chocolate chips (400 - x) is mixed evenly into 3 pans of brownies

(400 - x) / 3

Therefore, the answer is given by the expression:

(400-x) / 3

actual length = 171.67 ft.

Step-by-step explanation:

scale of school bus drawing is 12 in. to 5 ft.

if the length of a school bus drawing is 412 in.

                                                     5 ft

the actual length is    = 412 in x --------

                                                     12 in

actual length = 171.67 ft.

The required actual length of the bus is 171.7 feet.

Given that,
A scale drawing of a school bus has a scale of 12 inches to 5 feet.
The length of the school bus is 412 inches on the scale drawing,
To determine the actual length of the bus.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

here,
Scale given,
12 inches = 5 feet
1 inch = 5 / 12 feet
Now on the drawing, the length of the bus is 412 inches,
Now,
the actual length of the bus is,
= 412 * 5 / 12
= 171.7 feet

Thus, the required actual length of the bus is 171.7 feet.

Answer:

D

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 3, thus

y = - 3x + c ← is the partial equation

To find c substitute (2, - 5) into the partial equation

- 5 = - 6 + c ⇒ c = - 5 + 6 = 1

y = - 3x + 1 → D

The equation of the line is y=-3x+1. Therefore, option D is the correct answer.

Given that, the coordinate point is (2, -5) and the slope m is -3.

The equation of a line can be written many different ways, and each of these ways is valid. The slope-intercept form of a line is a way of writing the equation of a line so that the slope of the line and the y-intercept are easily identifiable. The slope is the steepness of the line, and the y-intercept is the place the line crosses the y-axis.

Put (x, y)=(2, -5) and m=-3 in y=mx+c, we get

-5 = (-3)(2) + c

⇒ c = 1

Substitute m=-3 and c=1 in y=mx+c, that is

y=-3x+1

The equation of the line is y=-3x+1. Therefore, option D is the correct answer.

Answer:

f(-2) = 4

Step-by-step explanation:

The function has three definitions depending on the value of x.

You are looking for the value of the function at x = -2.

-2 is in the interval x <= -1, which is the first line of the definition of the function.

We use the first line of the definition of the function.

f(x) = -2x for x <= -1

f(-2) = -2(-2) = 4

Cost of meat = $15

Step-by-step explanation:

Given:

Pepperoni costs = $3.50

Parma ham costs = $6.50

Total spend = $25

Find:

Cost of meat

Computation:

Cost of meat = Total spend - Pepperoni costs - Parma ham costs

Cost of meat = $25 - $6.50 - $3.50

Cost of meat = $15

Answer:

B

Step-by-step explanation:

A] You download 2 songs.

B] You download 2 movies.

C] You download 1 song and 1 movie.

D] You don't have enough money for 2 downloads.

x= number of movies downloaded

g(x) = total cost in dollars.

From g(x)=x

There is a slope of 1

That is, the movies cost $1 per movie.

It is a proportional relationship because of the absence of y-intercept

f(x) has a slope of (1/2) and y-intercept $2

f(x) = (1/2)x + 2 is the function for the cost of downloading music.

When we get to 3 downloads,

f(3)=g(3) and above, music downloads will be cheaper because they only cost 1/2 dollar for each additional movie compared to $1 for each movie.

For 2 movie downloads

we have,

f(2)=3

g(2)=2

So, downloading two movies will be cheaper.

One of each costs $1 + $2.50,

more than either of the other choices.

A parallelogram are shapes with 4 sides. To find its area, we must do the following formula.

(For rectangle, etc...)

Area = Length × Width

A represents Area

L represents Length

(For a square)

Area = Side × Side

A represents Area
