We want to factor the following expression:
16x4 – (y - 1)
We can factor the expression as (U+V)(U - V) where U and V are either constant integers or single-variable expressions.
What are U and V?

Answer: Choice B

(-2, 5)

==================================================

Explanation:

The original system is

[tex]\begin{cases}-4x+3y = 23\\ x-y = -7\end{cases}[/tex]

Multiply both sides of the second equation by 3. Doing so leads to this updated system of equations

[tex]\begin{cases}-4x+3y = 23\\ 3x-3y = -21\end{cases}[/tex]

Now add straight down

The x terms add to -4x+3x = -1x = -x

The y terms add to 3y+(-3y) = 0y = 0

The terms on the right hand sides add to 23+(-21) = 2

We end up with the equation  -x = 2 which solves to x = -2

Now use this to find y. You can pick any equation with x,y in it

----------------

-4x+3y = 23

-4(-2)+3y = 23

8+3y = 23

3y = 23-8

3y = 15

y = 15/3

y = 5

Or

x-y = -7

-2-y = -7

-y = -7+2

y = -5

y = 5

Either way, we get the same y value.

So that's why the solution is (x,y) = (-2, 5)

Answer:

The side length of each square is 2.12 units.

The length ad width of the rectangle are 2.12 and 4.24 units

Step-by-step explanation:

Let the width of the rectangle is x,

So, the length of the rectangle is 2x.

Area of the rectangle = 9 sq. units

[tex]9 = 2x \times x[/tex] [as area = length x width]

[tex]\Rightarrow 9 = 2x^2[/tex]

[tex]\Rightarrow x^2 = \frac{9}{2}=4.5[/tex]

[tex]\Rightarrow x = 1.5\sqrt{2}=2.12[/tex] units

So, width of the rectangle, x= 2.12 units and

the llengthof the rectangle, 2x= 2 x 2.12= 4.24 units.

After division of the rectangle into two equal square, so, the area of each square will be half of the area of the rectangle.

The area of the rectangle = 9/2=4.5 square units.

Let a be the length of the sides of the square, so

Area [tex]= a^2[/tex]

[tex]\Rightarrow a^2=4.5[/tex]

[tex]\Rightarrow[/tex] [tex]a = 1.5\sqrt{2}=2.121[/tex]

Hence, the side length of each square = 2.12 units.

Answer:

The wire should be placed at a height of 2.25 inches from the bottom

Step-by-step explanation:

With the assumption that the shape of the solar hot-dog cooker is a parabola. we have the equation for the shape given as y = a·x² + b·x + c

Whereby the coordinates of the vertex is taken as (h, k) = (0, 0), we have;

c = 0

∴ y = a·x² + b·x

From the diagram, we have;

When x = 6, y = 4

When x = -6, y = 4

Which gives;

4 = a·(-6)² + b·(-6) = 36·a - 6·b

4 = 36·a - 6·b.........................................(1)

4 = a·(6)² + b·(6) = 36·a + 6·b

4 = 36·a + 6·b........................................(2)

Subtracting equation (1) from equation (2) gives;

4 - 4 = 36·a - 6·b - (36·a + 6·b) = -12·b

0 = -12·b

b = 0

Therefore;

4 = 36·a - 6×0

a = 4/36 = 1/9

The focus = F(h, k + p)

p = 1/(4·a) = 1/(4 × 1/9) = 1/(4/9) = 9/4 in = 2.25 inches

The coordinates of the focus, F = (h, k + p) = (0, 9/4) = (0, 2.25)

Therefore, the wire should pass through the focus and placed at 2.25 inches above the bottom.

Total cost of the material is 16.06!!!

Step-by-step explanation:

Find the cost of 2 yards. 5.84*2=11.68.

5.84*0.75=4.38

Add them together.

11.68+4.38=16.06!

Step-by-step explanation:

this is a linear programming problem.

the objective is to maximize profit

let the chocolate be x

and cookies be y

Maximize

2.5x+2y=P

constraint milk

3x+y=9------------------1

constraint flour

2x+4y=16----------------2

solving 1 and 2

3x+y=9

2x+4y=16

multiply 1 by 2 and 2  3 to eliminate x we have

  6x+2y=18

 6x+12y=48

-0-10x=-30

10y=30

y=30/10

y=3

put y= 3 in eqn 1 we have

3x+3=9

3x=9-3

3x=6

x=6/3

x=2

two trays of chocolate

three trays of cookies

2.5x+2y=P

2.5(2)+2(3)=P

5+6=P

P=$11

Answer:

Step-by-step explanation:

AB // CD and E F is transversal

∠  E FA = ∠F ED     {alternate interior angles}

∠E FA = x

In Δ AG F,

∠G FA + ∠F AG +∠AG F = 180   {angle sum property of triangle}

x  + 2 x + 3 x = 180         {Combine like terms}

               6 x = 180        {divide both sides by 6}

                x = 180/6

x = 30

Answer:

(see below)

Step-by-step explanation:

You can also solve this algebraically:

–5 – (–3)

–5 + 3

–2

Since it can't be negative units between two points on a number line, you can multiply it by –1 to make it a positive number:

–2 (–1)

2 units

Or, you can use a number line. I have screenshotted a number line attached below for you.
