Use a table, diagram, or equation to justify your answer.​

Answers

Answer:

48 questions.

Step-by-step explanation:

x is for the unknown variable, the number you are trying to figure out.

12= 25%x

if you convert to a fraction, 12 is 1/4 of x. if you then multiply your answer by 4, 12 is 25% of 48.

to figure this out you can also ask, 12 is 25% of what number?

Make x the subject of the formula 3 ( c − b x ) = 18

Answers

Answer:

- 6-c/b

Step-by-step explanation:

3 ( c − b x ) = 18

=> c - bx = 18/3

=> -bx = 6 - c

∴ x = - 6-c/b

Hopefully this helps!!

The given formula written in the form of x as the subject is obtained as  x = (c - 6)/b.

What is a Linear equation?

A linear equation is a equation that has degree as one.

To find the solution of n unknown quantities n number of equations with n number of variables are required.

The given formula is  3(c − bx) = 18.

It is in the form of a linear equation.

It can be rewritten as follows,

3(c − bx) = 18

⇒ c − bx = 18/3

⇒ bx = c - 6

⇒ x = (c - 6)/b

Which implies the formula written as x as the subject.

Hence, the required form of the given formula is  x = (c - 6)/b.

Solve the System of Equations
3x^2-5y^2= 22
2x^2+4y^2 = 22

Answers

Lets try one way to solve this system. First, we want to isolate one of the unkown, lets choose y, so we need to remove x from an equation. In order to remove x from an equation, thats what we are going to do :

Line 1:

(3x² - 5y²) * 2 = 22 * 2

6x² - 10y² = 44

We simply multiplied Line 1 by the number 2, this doesn't change anything on the nature of Line 1.

Line 2:

(2x² + 4y²)*3 = 22*3

6x² + 12y² = 66

We simply multiplied Line 2 by the number 3, this doesn't change anything on the nature of Line 2.

Solving your system of equations is exactly the same thing as solving this new system of equation :

6x² - 10y² = 44

6x² + 12y² = 66

It is exactly the same. But it is easier now, because we can remove x from the equation simply by subtracting line 2 from line 1 :

L1 - L2 :

(6x² - 10y²) - (6x² + 12y²) = 44 - 66

6x² - 10y² - 6x² - 12y² = - 22

- 22y² = - 22

y² = 1

y = + 1 or y = - 1

We know have the value of y, we just have to replace it in the equation to solve the entire system :)

3x² - 5y² = 22

since y² will always be equal to one, wether y = 1 or y = - 1, we can write :

3x² - 5 = 22

3x² = 22 + 5

3x² = 27

x² = 27/3

x² = 9

x = + 3 or x = - 3

So the solutions are the following couples in the form (x,y) :

S = { (3 ; 1) , (-3;1) , (3 ; - 1) , (-3 ; -1))

Bryan can run 2 miles in 20 minutes. How many miles can he run in 100 minutes?

Answers

Answer:

If Bryan can run 2 miles in 20 minutes, he can run 10 miles in 100 minutes.

Step-by-step explanation:

To determine the answer to this problem, we can first find how many minutes it takes Bryan to run one mile. Because it takes him twenty minutes to run two miles, it must take Bryan ten minutes to run one mile.

1 mile = 10 minutes

Multiply this by ten to find how many miles Bryan runs in 100 minutes.

10 miles = 100 minutes

Bryan can run 10 miles in 100 minutes.

Answer: 10 miles

Step-by-step explanation: They’re equivalent to the minutes. 20 minutes 2 miles, 40 minutes 4 miles and so on.

triangles one and two are both isosceles meaning they each have two equal sides they each have a 30-degree angle explain why these triangles do not have to be similar to each other

Answers

Answer:

See below for answers

Step-by-step explanation:

These triangle do not have to be similar to each other because the 30° angles  may not be located in the same place.

For example, place one 30° at the vertex of the triangle which is  located where the two equal legs of the isosceles triangle are joined.  The triangle angles measure are 30°, 75°, and 75°.

But if the 30° angle is one angle at the base of the isosceles triangle, then the angles measure are 30°, 30°, 120°.

C. y - 1 = -4(x - 2)

Step-by-step explanation:

1. To find which line equation doesn't go through through the two points, we plug in the values of x to see if we get the value of the y.

A:

[tex]y=-4(3)+6[/tex] [tex]y = -12 + 6[/tex] [tex]y = -6[/tex] ✓ [tex]y = -4(1)+6[/tex] [tex]y = -4 + 6[/tex] [tex]y = 2[/tex] ✓

B:

[tex]y+6=-4(3-3)[/tex] [tex]y + 6 = -4(0)[/tex] [tex]y + 6 = 0[/tex] [tex]y + 6 - 6 = 0 - 6[/tex] [tex]y = -6[/tex][tex]y + 6 = -4(1-3)[/tex] [tex]y + 6 = -4(-2)[/tex] [tex]y + 6 = 8[/tex] [tex]y = 2[/tex]

C:

[tex]y-1=-4(3-2)[/tex] [tex]y-1=-4(1)[/tex] [tex]y-1=-4[/tex] [tex]y = -3[/tex]  

Therefore, the answer is C. y - 1 = -4(x - 2).

7. The perimeter of a rectangular pool is 70 meters. If the width of the pool
is 12 meters, then find its length.

Answers

Answer:

23 meters

Step-by-step explanation:

You would subtract 24 from 70, and then divide by two.

70-24=46

46/2 = 23

P of rectangle = 2 length + 2 width

> 70 = 2length + 24
Subtract 24 from both sides
> 46 = 2length
Divide by 2
> 23= length

The length of the pool is 23 meters

Find the equation of the line L.

Answers

Answer:

y = ([tex]-\frac{1}{2}[/tex])x + 4

Step-by-step explanation:

(x1,y1) = (0,4) ; (x2,y2) = (8,0)

The equation will look like y=mx+b

Slope m = [tex]\frac{rise}{run}[/tex] =  [tex]\frac{y2-y1}{x2-x1}[/tex] = [tex]\frac{0-4}{8-0}[/tex] = [tex]\frac{-4}{8}[/tex] = [tex]-\frac{1}{2}[/tex]

Next, substitute either x1y1 or x2y2 (it's gonna give the same answer anyways) and m to the equation y=mx+b to find b.

y=mx+b

0 = ([tex]-\frac{1}{2}[/tex])8 + b

0 = -4 +b

0+4 = -4 +4 +b

b=4

Then substitute b and m to the equation y=mx+b

y = mx + b

y = ([tex]-\frac{1}{2}[/tex])x + 4

Write the equation of the line in fully simplified slope-intercept form. ​

Answers

Answer:

 y = 4/3x - 3

Step-by-step explanation:

1. Find two pints on the line: ((3,1) and (6, 5).

2. Find the slope: Slope = (change in y-values)/(change in the x-values).

   Slope = (5 - 1)/(6 - 3) = 4/3

3. Use the slope and one point and substitute into y = mx + b to solve for "b"

     y = mx + b                 slope = 4/3   and point (3, 1)

      1 = 4/3(3) + b              4/3 · 3/1 =  12/3 = 4

      1 = 4 + b

      1 - 4 = b

       -3 = b

4.  Write the equation of the line: m = 4/3 and b = -3  Substitute into y = mx + b

      y = 4/3x - 3
