An equation for the total cars and trucks for dealership A is: x + y = 164.

An equation for the total cars and trucks for dealership B is: 2x + 0.5y = 229.

The number of cars that dealership A sold is: 98 cars.

The number of trucks that dealership B sold is: 66 trucks.

How to write a system of equations to model this situation?

In order to write a system of linear equations to describe this situation, we would assign variables to the number of cars sold and number of trucks sold, and then translate the word problem into an algebraic equation as follows:

Let the variable x represent the number of cars sold.Let the variable y represent the number of trucks sold.

Since the first dealership sold a total of 164 cars and trucks, a linear equation to model this situation is given by;

x + y = 164.

Additionally, the second dealership sold twice as many cars and half as many trucks as the first dealership, with a total of 229 cars and trucks;

2x + 0.5y = 229.

By solving the systems of linear equations simultaneously, we have:

2x + 0.5(164 - x) = 229

1.5x + 82 = 229

x = 98 cars.

For the y-value, we have;

2(98) + 0.5y = 229

0.5y = 229 - 196

y = 33/0.5

y = 66 trucks.

34+25 divided by 1/4

Answers

34 + 25 divided by 1/4 is the same as 34 + 100, which equals 134.

To divide by a fraction, you can multiply by its reciprocal. In this case, 1/4 is the same as 4/1, so we can rewrite the expression as:

34 + 25 x 4/1 = 34 + 100 = 134.

What are the two values on a number line that are a distance of 5 from 0?

Answers

Answer:

5 and -5

Step-by-step explanation:

For a number line the centre of the line is the origin (0, 0). To get the two numbers that are a distance of 5 from 0, we will add 5 to 0 and subtract 5 from 0.

Towards the positive x axis;

The value at a distance of 5 from 0 = 5- 0 = 5

Towards the negative x axis;

The value at a distance of 5 from 0 = -5- 0 = -5

Hence the  two values on a number line that are a distance of 5 from 0 are 5 and -5

Step-by-step explanation:

We have the two equations

\(\begin{aligned}2ax + 2y &= b \cdots\cdots [1]\\ 5 x + y &= -6 \cdots\cdots [2]\\\end{aligned}\\\)

Multiply equation [2] by 2

\(10x + 2y = -6 \cdots\cdots[3]\)

There will be an infinite number of solutions when both equations [1] and [3] are exactly the same:
For this to happen the right sides must be the same
So b = -6

Also 2ax = 10x
so 2a = 10

a = 5

So the ordered pair(5, -6) results in an infinite number of solutions

What are the solutions to the equation 0=|3x+3|+3

Answers

Therefore, the solutions to the equation 0 = |3x + 3| + 3 are x = -2 and x = 0.

To solve the equation 0 = |3x + 3| + 3, we need to eliminate the absolute value. Remember that the absolute value of a number is always non-negative.

First, let's isolate the absolute value term on one side of the equation:

|3x + 3| = -3

Since the absolute value cannot be negative, there are no solutions to the equation as it stands. However, if we modify the equation to make the right side positive, we can find a solution.

To eliminate the absolute value, we can rewrite the equation as two separate equations, considering both the positive and negative cases:

   3x + 3 = -3

   -(3x + 3) = -3

Solving equation 1:

3x + 3 = -3

3x = -6

x = -2

Solving equation 2:

-(3x + 3) = -3

-3x - 3 = -3

-3x = 0

x = 0

What is the Equation of a Line of Best Fit?

The equation of a line of best fit is represented by the equation, y = mx + b, where m is the slope and b is the initial value.

1. Using two points, (72, 20) and (20, 80):

Slope (m) = change in y / change in x = (80 - 20)/(20 - 72) = 60/-52

Slope (m) = -1.15.

Substitute m = -3 and (a, b) = (72, 20) into y - b = m(x - a)

y - 20 = -1.15(x - 72)

y - 20 = -1.15x + 82.8

y = -1.15x + 82.8 + 20

y = -1.15x + 102.8

The equation of the best line of fit is y = -1.15x + 102.8.

2. Monthly heating cost, y, for a month with an average temperature of 35°F (x) will be calculated by substituting x = 35 into y = -1.15x + 102.8.

The distance from the south most ship to the observation is

Answers

The distance from the north most ship to the observation is 2.9 miles and the distance from the south most ship to the observation is 9.9 miles.

The bearing is defined as the angle measured clockwise from the north direction. A ship is anchored off a long straight shoreline that runs north and south.

From two observation points miles apart on shore, the bearings of the ship are 52 degrees and 134 degrees respectively. To find the distance from the ship to each of the observation points, we can use trigonometry.

Let's call the distance from the north observation point to the ship x, and the distance from the south observation point to the ship y. The bearings from the north and south observation points can be drawn as follows:

[asy]


unitsize(1cm);


pair O = (0,0), N = (-2,0), S = (2,0), A = (-2,1), B = (2,-1);


draw(O--N--A,Arrow);


draw(O--S--B,Arrow);


\(label("$52^\circ$", N + 0.3*dir(52), NE);\)


\(label("$134^\circ$", S + 0.3*dir(134), SE);\)

draw(O--A--B--cycle,dashed);


\(label("$x$", (N+A)/2, W);\)


\(label("$y$", (S+B)/2, E);\)


[/asy]

We can use the tangent function to find x and y, since we have the angle and opposite side.

From the north observation point, we have:

\($$\tan(52^\circ) = \frac{x}{2}$$$$x = 2\tan(52^\circ) \approx 2.95$$\)

From the south observation point, we have:

\($$\tan(134^\circ) = \frac{y}{2}$$$$y = 2\tan(134^\circ) \approx 9.88$$\)

Therefore, the distance from the north most ship to the observation is 2.9 miles and the distance from the south most ship to the observation is 9.9 miles.

2. Abigail and Curtis Siebert: $270,000 mortgage at 7% for 20 years.

Answers

M = 270,000 * (0.5833% * (1 + 0.5833%)^240) / ((1 + 0.5833%)^240 - 1).  Calculating this equation will give us the monthly mortgage payment for Abigail and Curtis Siebert.

Abigail and Curtis Siebert have a $270,000 mortgage at an interest rate of 7% for a term of 20 years.

To calculate the monthly mortgage payment, we can use the formula for an amortizing mortgage:

M = P * (r * (1 + r)^n) / ((1 + r)^n - 1),

where M is the monthly mortgage payment, P is the principal amount (loan amount), r is the monthly interest rate, and n is the total number of monthly payments.

First, we need to convert the annual interest rate to a monthly interest rate. Since there are 12 months in a year, the monthly interest rate is 7% divided by 12, which is approximately 0.5833%.

The total number of monthly payments is the term of the mortgage multiplied by 12. In this case, it's 20 years * 12 months, which equals 240 months.

Now, we can substitute the values into the formula:

M = 270,000 * (0.5833% * (1 + 0.5833%)^240) / ((1 + 0.5833%)^240 - 1).

Calculating this equation will give us the monthly mortgage payment for Abigail and Curtis Siebert.
