Answer: 16 square units

Step-by-step explanation:

let the vertex in quadrant I be (x,y)  

then the vertex in quadratnt II is (-x,y)  

base of the rectangle = 2x  

height of the rectangle = y  

Area = xy  

= x(12 - x²)  

= -x³ + 12x  

d(area)/dx = 3x² - 12 = 0 for a maximum of area  

3x² = 12  

x² = 4  

x = ±2  

y = 12-4 = 8

So, the largest area = 2 x 8 = 16 square units

Answer:

f = 0.9 pounds.

Step-by-step explanation:

Let f = weight of the football.

Let b = weight of the basketball.

Given the following data;

Weight of each basketball, b = 1.37 pounds

Translating the word problem into an algebraic equation, we have;

[tex] 3f + 2b = 5.44[/tex] ..........equation 1

[tex] b = 1.37[/tex] ....................equation 2

Substituting equation 2 into equation 1, we have;

[tex] 3f + 2(1.37) = 5.44[/tex]

[tex] 3f + 2.74 = 5.44[/tex]

Rearranging the equation, we have;

[tex] 3f = 5.44 - 2.74[/tex]

[tex] 3f = 2.7[/tex]

[tex] f = \frac{2.7}{3} [/tex]

f = 0.9 pounds

Therefore, the weight of each football is 0.9 pounds.

Answer:

slope = 0

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 4, 3) and (x₂, y₂ ) = (5, 3)

m = [tex]\frac{3-3}{5+4}[/tex] = [tex]\frac{0}{9}[/tex] = 0

Answer:

57 degrees

Step-by-step explanation

Answer:

x = 57

Step-by-step explanation:

So we know all triangles add up to 180 degrees. And that supplementary angles add up to 180 degrees.

So, we can do that missing angle + 138 = 180

180 - 138 = 42

180 - 42 - 81 = x = 57

Answer:

(0,2)

Step-by-step explanation:

Since x is by itself plug that in for the second equations x

X+8y =16

2y-4+8y=16 solve for y

10y-4=16

10y=20

Y=2

Plug 2 for y into the first equation

X= 2y-4

X=2*2-4

X=4-4

X=0

Those are your points, (0, 2)

Answer:

A)F(x)=1/(x+1)^2

Step-by-step explanation:

The rational functions which is graphed is f(x) =1/(x+1)², option A is correct.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

A relation is a function if it has only one y-value for each x-value.

Rational function is the ratio of two polynomial functions where the denominator polynomial is not equal to zero.

There are vertical asymptotes at -1.

Vertical asymptotes are present where x on the denominator is equal to 0

f(x) =1/(x+1)² is the rational function.

Hence, the  rational functions which is graphed is f(x) =1/(x+1)², option A is correct.

There are 20.65% of the total number of students increased on the honor roll.

Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.

Here, For last year

         Total boys for honor roll = 100

          total girls for honor roll = 84

          total students for honor roll = 100+84 = 184

For present year,

      Boys for honor roll = 100 + 100X0.17 = 117

      Girls for honor roll = 84 + 84X0.25 = 105

      Total students = 117 + 105 = 222

Increment in total students = 222 - 184 = 38

% increment in total student = 38 X 100 / 184

                                                = 0.2065 X 100

                                                = 20.65 %

Thus, there are 20.65% of the total number of students increased on the honor roll.

Given :

Price per folder = $2.15 .

Price per notebook = $4.60 .

The supply budget for this meeting is $150.

To Find :

Inequality represents the constraint on the number of folders f and notebooks n the office administrator can purchase.

Solution :

Let, number of folders and notebooks is f and n.

So, price of buying f and n number of folders and notebooks are :

P = 2.15f + 4.60n

Now, it is given that P ≤ $150 .

So,

2.15f + 4.60n ≤ 150

Hence, this is the required solution.

[tex]2.15f+2.5n\leq 150[/tex] inequality will represent the constraint on the number of folders f and notebooks n the office administrator can purchase.

Given information:

An office administrator will be purchasing supplies for an upcoming meeting.

Staff will purchase folders, which are $2.15 each, and notebooks, which are $4.60 each.

The supply budget for this meeting is $150.

Let f be the number of folders purchased and n  be the number of notebooks purchased.

Now, the total amount spent on the whole purchase should not be greater than $150 which is the budget of the shopping.

In the form of inequality, the given condition can be written as,

[tex]2.15f+4.6n\leq 150[/tex]

The total amount spent is less than equal to 150.

Therefore, [tex]2.15f+4.6n\leq 150[/tex] inequality will represent the constraint on the number of folders f and notebooks n the office administrator can purchase.

[tex]2\ and\ -2[/tex]

Step-by-step explanation:

If a polynomial intersects the x-axis at (2,0) and (-2,0)

Then the zeroes are at x=2 and x=-2

(Outside of the question)

To find factors using the zeroes, we must have one side of the equation equal to zero.

x=2

x-2=0

factor (x-2)

x=-2

x+2=0

factor (x+2)

Answer:

25

Step-by-step explanation:

5(x+6)−(5−x)−6x

Remember PEMDAS

P – Parentheses

E – Exponents

M – Multiplication

/D – Division  (whichever comes first from left to right)

A – Addition

/S – Subtraction (whichever comes first from left to right)

First, let's distribute the left side:

5 * x = 5x

5 * 6 = 30

5x + 30

Now, lets distribute the right side

-(5 - x) = -1(5 - x)

-1 * 5 = -5

-1 * -x = x  ( - * - = +)

x - 5

Now we have:

5x + 30 + x - 5 - 6x

Let's combine like terms.

5x, -6x, and x are like terms. 5x + x =  6x - 6x = 0

30 and -5 are like terms. 30 - 5 = 25

25

Since we can't simplify this any further, that is our answer.
