2) choice A, theyre equal in length

3) Choice D, (-3,0) (-3, -3) (-1, -3)

4) Choice A, Clockwise 90- degree rotation

Step-by-step explanation:

Answer 2

The statements which describe A'B' is:

A'B' and AB are equal in length ⇒ (B)

Step-by-step explanation:

Let us take about reflication:

⇒ Reflections are mirror images, means the shape or the size of

  the figure does not affect by reflection, think of "folding" the

  graph over the y-axis or the x-axis

⇒ On a grid, you used the formula (x, y) → (-x, y) for a reflection in

   the y-axis and used the formula (x, y) → (x, -y) for a reflection in

   the x-axis.

In our question segment AB, where A = (1, 3) and B = (5, 3) is

reflected about the y-axis

By using the rule above

∴ A' =(-1, 3)

∴ B' = (-5,3)

∵ Reflection does not change the shape or the size of the original figure

∴ Line segment A'B' has the same length of line segment AB

The correct answer is:

A'B' and AB are equal in length

You can check your answer by finding the lengths of AB and A'B'

∵ The length of AB = 5 - 1 = 4 units

∵ The length of A'B' = -1 - (-5) = -1 + 5 = 4 units

∴ AB = A'B'

Note:

If the y-coordinates of two points are equal, then the line joining them is horizontal and its length is the difference between the x-coordinates of the two points.

angle a and b are supplementary angles. angle where a = 30+2x and b =x what is the measure of b degress

Answers

Answer:32  times 4 -  8 in degrees

Step-by-step explanation:

Since b = x, hence the value of b is 30 degrees

For two angles to be supplementary, the sum of the angles must be equal to 180 degrees

Given the angles

a = 30 + 2x

b = x

Equating the sum to 180

a + b = 180

30+2x + x = 180

30 + 3x = 180

3x = 180 - 30

3x  = 150

x = 30 degrees

Since b = x, hence the value of b is 30 degrees

The resulting value for the given sum of trignometry identity is -2

Trigonometry identity

Trigonometry identity are written in tems of sine, cosine and tangent

According to the trigonometry identity

sec theta = 1/costheta

cot theta = 1/tantheta

Given the trigonometry expression

sec 180 + sin 270 - tan 180 + cot 270

This can also be written as;

1/cos180 + sin270 - tan 180 + 1/tan270

= -1/cos0 + (-sin90)  - tan0 +1/tan90

= -1 - 1 - 0 +1/∞

= -1 -1 + 0
= -2

Hence the resulting value for the given sum of trignometry identity is -2

Joseph and Wendy were catching tadpoles. At first Wendy caught nine times three more than Joseph caught. Joseph was upset and released half of Wendy 's tadpoles, and then six times as many as Joseph caught swam away. After all of this, Wendy only had three tadpoles left. How many tadpoles did Joseph catch?

Answers

Answer:

Joseph caught 7 tadpoles

Step-by-step explanation:

Let the number of tadpoles caught by Joseph be x

The number of tadpoles Wendy caught will be ;

9(x + 3)

After Joseph was upset, he released half of Wendy’s tadpole and then six times as many as Joseph caught swam away leaving Wendy with only three tadpoles left;

Hence, mathematically;

9(x + 3)/2 - 6x = 3

Multiply through be 2

9(x + 3) - 12x = 6

9x + 27 -12x = 6

9x -12x = 6-27

3x = 21

x = 21/3

How can you use the graph of a quadratic equation to determine the number of real solutions of the equation?​

Answers

Answer:

Step-by-step explanation:

The number of real solution of a quadratic equation can be found from the number of x-intercepts on the graph. If the curve passes through the x-axis twice, (2 x-intercepts), then the equation has two real solutions.

If it passes through once, (the vertex is on x-axis), then there is one real solution, and if it does not touch the x-axis at all (floating above it or below it), then it has no real solutions.

Hope this helped!

Find three consecutive integers such that when three times the third is increased by the first, the result is 8 less than five times the second.

Answers

Answer:

           9, 10 and 11

Step-by-step explanation:

x - the smallest of three consecutive integers (the first)

x+1 - the next of three consecutive integers (the second)

x+2 - the last of three consecutive integers (the third)

3(x+2) - three times the third integer

3(x+2)+x - three times the third increased by the first

5(x+1)   - five times the second tnteger

5(x+1)-8  - 8 less than five times the second

3(x + 2) + x = 5(x + 1) - 8

3x + 6 + x = 5x + 5 - 8

   4x + 6 = 5x - 3

       -4x        -4x

        6 = x - 3

Step-by-step explanation:

The burger was 3 dollars and 50 cents . The two order of fries were 3 dollars

Answer:

$3.50

Step-by-step explanation:

first you take the amounts you do know, which is the total amount and the cost of one order of fries.

you know he got 2 fries, so thats 1.50 times 2.

1.50 x 2 = 3.00

To manage a rental property, a property manager charges $65 per month plus 6% of the rent.
If Jack pays the property manager $164 each month, what is the monthly rent on his property?

Answers

Given parameters:

Charge per month  = $65

Percentage on rent= 6%

Amount paid by Jack per month = $164

Unknown:

Monthly rent on his property = ?

Solution:

  Monthly rent on his property can be found by;

  Amount paid by Jack per month = Charge per month + 6% of monthly rent

Let the monthly rent = x ;

  So;

              164  = 65 + [tex]\frac{6}{100} x[/tex] x

              164 - 65  = [tex]\frac{6x}{100}[/tex]

                   99  = [tex]\frac{6x}{100}[/tex]

                    x = 1650

Monthly rent on his property is $1650
