The answer is B: (-1, 2)

Step-by-step explanation:

Imagine a mirror is placed along the y-axis.

Since a reflection is applied, the mirror coordinates would be the opposite of the original coordinates, just like a mirror is opposite of what you see when you look into it.

Original coordinates: (1, 2)

Mirror coordinates: (-1, 2)

7a.C

7b.Angle AED

7c.Angle 8

7d. Angle 6 and 8

Step-by-step explanation:

6a. The labeled angles are vertical angles so we set them equal to each other.

[tex]7x - 8 = 6x + 11[/tex]

[tex]7x = 6x + 19[/tex]

[tex]x = 19[/tex]

7a.Angle 11 is near Point C so Point C is the vertex.

7b. Angle 5 vertex is E so we can use any 3 points as an angle as long as E is in the middle example, and the angles are on the left side so we can use

[tex]aed[/tex]

Write the angle sign as well.

7c. Angle 6 is vertical from Angle 8.

7d. Angle 7 and 6 form a linear pair and since Angle 6=Angle 8, Angle 7 and 8 form a linear pair as well.

Write the equation for each graph.

[tex]\frac{x-1}{x+2}[/tex]

Step-by-step explanation:

simplifying the equation:  [tex]x^2-3x+2/x^2-1[/tex]

1) Rewrite the equation so it's easier to understand:

[tex]\frac{x^2-3x+2}{x^2-4}[/tex]

2) factor [tex]x^2-3x+2[/tex]:

[tex]x^2-3x+2[/tex] [tex]=> (x-1)(x-2)[/tex]

3) factor [tex]x^2-4[/tex]:

[tex]x^2-4 => (x+2)(x-2)[/tex]

Meaning: [tex]\frac{(x-1)(x-2)}{(x+2)(x-2)}[/tex]

4) Cancel the common factor: [tex](x-2)[/tex] from the numerator and the denominator:

Step-by-step explanation:

Using the tangent ratio in the right triangle and the exact value

tan30° = [tex]\frac{1}{\sqrt{3} }[/tex] , then

tan30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{a}{12}[/tex] = [tex]\frac{1}{\sqrt{3} }[/tex] ( cross- multiply )

a × [tex]\sqrt{3}[/tex] = 12 ( divide both sides by [tex]\sqrt{3}[/tex] )

Allen wants to have a mean of 90 on his math quizzes. So far, he has scored 86, 94, 88, 95, and 89. What is the least score that Allen needs on his next quiz to have a mean of 90?

Answers

Answer:

88

Step-by-step explanation:

[tex] \frac{86 + 94 + 88 + 95 + 89 + x}{6} = 90[/tex]

The mean would be the sum of all the math quiz grades divided by the number of quizzes taken.

Solve for x:

[tex]86 + 94 + 88 + 95 + 89 + x = 540[/tex]

[tex]452 + x = 540[/tex]

[tex]x = 88[/tex]

Thus, Allen needs at least an 88 to obtain a mean of at least 90.

Mr. Jennings is shopping for a car loan. He wants to buy a car that costs $18,000. He plans to pay $5,000 in cash and get a loan for the rest. If the annual interest rate on the loan is 5%, how much interest will he pay in the first year?

Answers

Answer:

$650

Step-by-step explanation:

Interest = amount of the loan x interest rate x time

Amount of the loan = price of the car - cash payment

$18,000 - $5,000 = $13,000

interest rate = 5%

time = 1 year

$13,000 x 0.05 x 1 = $650
