Answer:

[tex]y + 2 = \frac{2}{3}(x+1)[/tex]

Step-by-step explanation:

Parallel lines are parallel because they never intersect. As such, they have the same slope. The slope of the line y = 2/3x + 7 is 2/3. Substitute m = 2.3 and the point (-1,-2) into the point slope form of a line.

[tex]y -y_1 = m(x-x_1)\\y --2 = \frac{2}{3}(x --1)\\y + 2 = \frac{2}{3}(x+1)\\[/tex]

Answer:

Step-by-step explanation:

Each factor corresponds to a zero of the function.

If (x+4) is set = to 0, the corresponding root is x = -4.

If (-7x - 60) is set = to 0, the corresponding root is x = -60/7.

The factors (-7x-60)(x+4) represent the roots or solutions of the original quadratic equation in its expanded form, which are obtained by setting each factor equal to zero and solving for x.

The factors (-7x-60)(x+4) in the factored form represents the roots of a quadratic equation. In a quadratic equation of the form ax² + bx + c = 0, the roots or solutions of the equation can be obtained by factoring the quadratic expression. In this case, the equation being factored must have been -7x² - 28x - 60x - 240 = 0. The roots are the values that make each factor equal to zero, so the roots of the original equation are obtained by solving -7x-60 = 0 and x+4 = 0, to get x = -60/(-7) = 8.57 and x=-4.

Answer: The total is $12,250.

Step-by-step explanation: First, we will calculate the amount that Hillary has deposited over the past 35 years. She has deposited $200 for each of the past 35 years. The total that she has deposited is 200 x 35 = $7,000.

Her employer also deposits into her account 75% of what she has deposited. In order to calculate their contribution you need to multiply $7,000 x .75 = $5,250.

The total that has been deposited into the account is $7,000 + $5,250 = $12,250.

Hillary's total contribution over the 35 years was $84,000. The employer matched 75% of Hillary's contribution, totaling $63,000. The combined contribution of Hillary and her employer for 35 years is $147,000.

Hillary has been depositing $200 into her 401(k) per month for the past 35 years. For 35 years, there are a total of 35 times 12 months which equals 420 months. Given this, Hillary has contributed $200 times 420 months which is $84,000.

Her employer has a 75% match on all her contributions. This means they are adding another 0.75 times the $84,000, which equals $63,000.

Therefore, the total contribution by both Hillary and her employer over the 35 years is both amounts added together: "$84,000 (Hillary’s contribution) + $63,000 (Employer match) = $147,000".

Answer:

Reflection across the line y=x followed by translation 10 units to the right and 4 units up.

Step-by-step explanation:

Triangle ABC has vertices at points A(-6,2), B(-2,6) and C(-4,2).

1. The reflection across the line y=x has the rule

(x,y)→(y,x).

Thus,

2. The translation 10 units to the right and 4 units up has the rule

(x,y)→(x+10,y+4).

Thus,

Points A'B'C' are exactly the vertices of the triangle A'B'C'.

The sequence of transformations that maps triangle ABC to triangle A’B’C’ is a reflection across the y-axis, followed by a translation 8 units to the right and 10 units up.

The sequence of transformations that maps triangle ABC to triangle A’B’C’ is a reflection across the y-axis, followed by a translation 8 units to the right and 10 units up.

First, the reflection across the y-axis changes the x-coordinate to its opposite. So, the new coordinates of point A are (-2, 5), the new coordinates of point B are (-3, 2), and the new coordinates of point C are (-5, -1).

Next, the translation moves the triangle 8 units to the right and 10 units up. So, the new coordinates of point A are (6, 15), the new coordinates of point B are (5, 12), and the new coordinates of point C are (3, 9).

Answer:

Area = 30 , Perimeter = 22.31 ⇒ Answer (B)

Step-by-step explanation:

* Lets study the figure

- The length of AE = 5

- The length of DC = 3

- The length of BC = 4

- Tho find the length of DE and AB we must use Pythagoras Theorem

∵ The vertical distance of ED = 3 and the horizontal distance = 2

∴ ED = √(3² + 2²) = √13  

- Similar we will find AB

∵ The vertical distance of AB = 6 and the horizontal distance = 3

∴ AB = √(6² + 3²) = √45

* Now we can find its perimeter

- The perimeter = 5 + 4 + 3 + √13 + √45 = 22.31

* to find the area we will divided it into 2 trapezium

- The first one contains E , D , C with point of intersection

 between the vertical axis with side CB

- The lengths of its 2 parallel bases are 3 , 6 and height 2

- The second one contains E , A , B with  point of intersection

 between the vertical axis with side BC

- The lengths of its 2 parallel bases are 2 , 5 and height 6

∵ Area trapezium = (1/2)(b1 + b2) × h

- The area of 1st one = (1/2)(3 + 6) × 2 = 9 units²

- The area of 2nd one = (1/2)(2 + 5) × 6 = 21 units²

∴ The area of the figure = 9 + 21 = 30 units²

* Area = 30 , Perimeter = 22.31

6.  Jim's house is 5.1 miles from the mall

7. Jim's house is closer to the mall by 0.3 miles.

8. The total distance of the round trip is 5.7 miles + 5.7 miles = 11.4 miles.

Since Jim's car has 25 miles until it runs out of gas and the round trip is 11.4 miles, Jim would be able to make it from his house to the grocery store and back without stopping for gas.

9. Jim had traveled 5.4 miles / 2 = 2.7 miles when his wife called.

10. The park is within 5 miles of Jim's house.

6. How many miles is Jim's house from the mall?

To find the distance between Jim's house and the mall, we can use the distance formula:

distance = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) and (x2, y2) are the coordinates of the two points.

In this case, the coordinates of Jim's house are (12, 11) and the coordinates of the mall are (7, 10). Plugging these values into the distance formula, we get:

distance = sqrt((7 - 12)^2 + (10 - 11)^2)

distance = sqrt(25 + 1)

distance = sqrt(26)

distance = 5.1 miles (rounded to the nearest tenth)

Therefore, Jim's house is 5.1 miles from the mall

7. Is Jim's house closer to the mall or the bank? How many miles closer is it?

To find which point is closer to Jim's house, we can calculate the distance between Jim's house and each point and compare the results.

The distance between Jim's house and the bank is:

distance = sqrt((14 - 12)^2 + (16 - 11)^2)

distance = sqrt(4 + 25)

distance = sqrt(29)

distance = 5.4 miles (rounded to the nearest tenth)

Therefore, Jim's house is closer to the mall by 0.3 miles.

8. Jim is at his house, and his car has 25 miles until it runs out of gas. Would Jim be able to make it from his house to the grocery store and back without stopping for gas? Explain.

To find out if Jim can make it from his house to the grocery store and back without stopping for gas, we need to calculate the total distance of the round trip.

The distance between Jim's house and the grocery store is:

distance = sqrt((16 - 12)^2 + (15 - 11)^2)

distance = sqrt(16 + 16)

distance = sqrt(32)

distance = 5.7 miles (rounded to the nearest tenth)

Therefore, the total distance of the round trip is 5.7 miles + 5.7 miles = 11.4 miles.

Since Jim's car has 25 miles until it runs out of gas and the round trip is 11.4 miles, Jim would be able to make it from his house to the grocery store and back without stopping for gas.

9. Jim left his house and drove to the bank. On his way back home, Jim's wife called when he was exactly halfway home. How many miles had Jim traveled when his wife called?

To find the distance Jim had traveled when his wife called, we can divide the total distance between Jim's house and the bank by 2.

The distance between Jim's house and the bank is:

distance = sqrt((14 - 12)^2 + (16 - 11)^2)

distance = sqrt(4 + 25)

distance = sqrt(29)

distance = 5.4 miles (rounded to the nearest tenth)

Therefore, Jim had traveled 5.4 miles / 2 = 2.7 miles when his wife called.

10. Jim is hoping that a park will be built within 5 miles of his house. If a park is built at the coordinates (12, 10), does that meet Jim's criteria? Explain.

To find out if the park is within 5 miles of Jim's house, we can calculate the distance between the park and Jim's house.

The distance between the park and Jim's house is:

distance = sqrt((12 - 12)^2 + (10 - 11)^2)

distance = sqrt(1)

distance = 1 mile (rounded to the nearest tenth)

Therefore, the park is within 5 miles of Jim's house.

Answer:

The answer is D.
