Write the equation of the line that is parallel to the given line and passes through the given point

Answers

The slope of parallel lines is the same, which is y = 5x - 12.

Parallel lines have the same slope in two dimensions. If we are aware of a point on the line and the equation of the supplied line, we can construct the equation of a line that is parallel to the given line.

Given: a line or point with a slope of m (x - x1), where m is the slope, and (x1,y1) is a point on the line, we obtain

y - (-1) = m (x - 2), and now the line is parallel to the one that was supplied. The slope is the SAME for parallel lines.

y + 2 = 5 (x - 2)

A line with a slope of y + 2 = 5x - 10 points...

Y = 5x – 12 – 2 – Subtract 2 from both sides.

Hence, the equation of the line that is perpendicular to the provided line and passes through has the form y = 5x – 12.

the difference between two numbers is -1. their sum is -27. find the numbers. let x represent the first number and y represent the second number. solve using system s of equations.​

Answers

Answer: x = -14, y = -13

Step-by-step explanation:

As stated by the question, we can use a system of equations to help us solve.

First, the difference between two numbers (x and y) is -1. The difference represents subtraction.

     x - y = -1

Next, the sum of the numbers (x and y) is -27. The sum represents addition.

     x + y = -27

Now, we can solve this system. We will graph both of the equations. The point of intersection is the solution, see attached. This gives us an answer of x = -14 and y = -13.

     x - y = -1

     x + y = -27

A truck can be rented from Company A for $70 a day plus $0.20 per mile. Company B charges $50 a day plus $0.70 per mile to rent the same truck. Find the number if miles in a day at which the rental costs for Company A and Company B are the same.

At ___ miles, the rental costs are the same from either company.

Answers

The computation shows that the number of miles is 40 miles.

How to compute the value?

Based on the information, Truck A will be: = $70 + 0.2m

Truck B = 50 + 0.7m

where m = number of miles

Therefore 50 + 0.7m = 70 + 0.2m

Collect like terms

0.7m - 0.2m = 70 - 50

0.5m = 20

m = 20/0.5

m = 40

The number of miles will be 40.

The area of a
parking lot is 600 square meters. A car requires 6 square
meters. A bus requires 30 square meters. The attendant can handle only
60 vehicles. If a car is charged $2.50 and a bus $7.50, how many of each
should be accepted to maximize income?

Answers

The number of cars should be 100 and that of bus be 0.

x is the number of cars and y is the number of buses.

Area: 6x + 30y <= 600 simplifies to x + 5y <= 100

Total money collected: 2.50x + 7.50 y …..this is what you want to maximize

OR you want to maximize 2.50 (x+ 3 y)

OR you want to maximize (x+3y)

Replacing the value of x from the Area equation in the above price, we get

100 - 5y + 3y is the maximum amount you can collect

So you want to maximize 100 - 2y. This happens when y is 0.

When y is 0; x will be 100 and you will collect 250.

Find domain of the following functions

Answers

The domain of the function g (x) = (x² - 2 x - 15) / (x² + x - 6) is R - {-3, 2}.

We are given a function:

g (x) = (x² - 2 x - 15) / (x² + x - 6)

We need to find the domain of the function.

We know that a function becomes not defined when the denominator becomes 0.

Put x² + x - 6 = 0

x² + 3 x - 2 x - 6 = 0

x (x + 3) - 2( x + 3) = 0

( x + 3 ) ( x - 2 ) = 0

We get x = - 3 and x = 2.

So, these cannot be the values of x

So, the domain is

Domain = R - {-3, 2}

Therefore, the domain of the function g (x) = (x² - 2 x - 15) / (x² + x - 6) is R - {-3, 2}.

Answers

The equation representing the situation is [tex]2.9+x = 29.7[/tex] where [tex]x[/tex] represents the pressure of barometric pressure when the eye of the hurricane passed over and pressure is 26.8 inches of mercury.

As per the question, The day after a hurricane, the barometric pressure in a coastal town has risen to 29.7 inches of mercury, which is 2.9 inches of mercury higher than the pressure that occurred when the eye of the hurricane passed over.

We are supposed to form an equation representing the situation and calculate the barometric pressure when the eye passed over.

Let's assume that [tex]x[/tex] represents  the pressure of barometric pressure when the eye of the hurricane passed over.

So using the concept of linear equation, we can form an equation as,

[tex]2.9+x = 29.7[/tex]

And pressure of barometric pressure when the eye of the hurricane passed over and pressure is

[tex]x=29.7-2.9\\x=26.8[/tex]

So 26.8 inches of mercury is the barometric pressure when the eye of the hurricane passed over.

You are borrowing $10840 to buy a car. If you pay the loan off in 6 years (72 months), estimate your monthly payment by ignoring interest and rounding the loan to the nearest hundred dollars.

Answers

If we are borrowing $10840 to buy a car and repaying it in 6 years (or 72 months) , our monthly payment will be $150.55 or rounded of $200.

As per the question statement, we are borrowing $10840 to buy a car and repaying it in 6 years (or 72 months) , what will be the estimate monthly payment by rounding off to the nearest hundred dollars

First we are supposed to find the monthly payment then we can round it off to the nearest hundred dollars.

Total loan borrowed = $10840

Time taken to pay it off = 6 years or 72 months,

Payment to be made per month = [tex]\frac{10840}{72} \\ 150.5556[/tex]

Therefore [tex]150.5556[/tex] dollars is to be paid every month for 72 months.

After rounding off to the nearest hundred dollars we will get $200.

Hence we are supposed to pay approximately $200 every month for 72 months.

In the fields of finance and economics, interest is the payment made at a set rate by a borrower or deposit-taking financial institution to a lender or depositor in excess of the principal amount (the amount borrowed).  It is not the same as a fee that the borrower might pay to the lender or another entity. Interest advance, but rather on a pro-rata basis as a share of the reward received by risk-taking business people when revenue is earned that exceeds all costs.

For Interest, a customer who borrows money from a bank typically pays interest on it, so they pay the bank more than they borrowed; likewise, a customer who earns interest on their savings may withdraw more than they originally put. When it comes to savings, the bank serves as the borrower while the consumer serves as the lender.

Jamaal puts $4100 in a savings bank account. The interest rate on the account is 1.8% compounded quarterly.
How much interest does Jamaal earn after a year?

Answers

The compound interest earned by Jamaal after a year is $4174.30.

What is defined as the compound interest?Compound interest essentially means that the interest on a bank account, lending, or investment grows exponentially over time rather than linearly.Compound interest advantages investors, but the term "investor" can mean a variety of things. Banks, for example, profit from compound interest once they lend money as well as reinvest the interest received in making more loans.

The formula for finding the compound interest is;

CI = p( 1 + r/n)∧nt

where p is the principal amount = $4100.

r is the rate of interest = 1.8% = 0.018.

t is the total time in years = 1 year.

n is the number of time interest given = 4 times.

Put the values;

CI = 4100( 1 + 0.018/4)∧4(1)

CI = 4100×1.018

CI = 4174.30

Thus, the amount of compound interest earned by Jamaal earned after an year is $4174.30.
