The difference of two numbers is 4. Their sum is 18. Find the numbers.

Answers

Answer 1

Answer:

11 and 7

Step-by-step explanation:

Let these two numbers be x and y where x is greater than y.

We can write two equations from the given information:

x - y = 4

and

x + y = 18

If we add them together, the y's cancel out:

x - y = 4

x + y = 18

2x = 22

x = 11

y is 4 less than x, meaning it is 7.

The two numbers are 11 and 7

Step-by-step explanation:

ranges are,

-1 , -11 and 7

hope this answer helps you dear!

Answer:

R = { - 11, - 1, 7 }

Step-by-step explanation:

Substitute the values from the domain into f(x) for range

f(2) = - 2(2)² + 7 = - 2(4) + 7 = - 8 + 7 = - 1

f(- 3) = - 2(- 3)² + 7 = - 2(9) + 7 = - 18 + 7 = - 11

f(0) = - 2(0)² + 7 = - 2(0) + 7 = 0 + 7 = 7

Then

R = { - 11, - 1, 7 }

Square ABCD has points A(5, 10) and B(-4, 3). What is the slope of line segment BC?

Answers

Given the square ABCD with points A(5, 10) and B(-4, 3), the slope of the line segment BC is 7/9

The formula for calculating the slope of a line is expressed as:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Given the coordinate point  A(5, 10) and B(-4, 3)

Substituting the given coordinate into the formula for slope

[tex]m=\frac{3-10}{-4-5}\\m=\frac{-7}{-9}\\m=\frac{7}{9}[/tex]

Hence the slope of the line segment BC is 7/9

Charlie's Computer Company charges $0.65 per pound to ship computers. Part A: Write an equation to determine the total cost, c, to ship p pounds of computers. Use your equation to determine the cost of shipping 2 pounds of computers. (6 points) Part B: If the company reduces the cost to ship computers by $0.05 per pound, write an equation to determine the total cost, c, to ship p pounds of computers with the reduced cost. (4 points)

Answers

Answer:

Part A:

Equation: 0.65p=c

Answer: $1.30

Part B:

Equation: 0.05p=c

Answer: $0.10, or ten cents (if two pounds of computers where shipped at this reduced price)

Step-by-step explanation:

To find the total cost, first find the elements you will need. We know that we need to equal c, the cost, and we know that the pounds times 65 cents equals the cost.

0.65p=c

Now, to solve, plug in the amount of pounds.

0.65(2)=c

1.3=c

So the cost of shipping two pounds of computers is $1.30.

Now, to solve part b, we do the same as what we did in part a, except this time it only costs five cents per pound.

Make the equation.

0.05p=c

Also, at the top I put the extra, if two pounds were shipped at the reduced price just in case. But for the explantion to it, just plug to into the equation, then find the answer.

Part A: The equation for the total cost, c, to deliver p pounds is:

c = 0.65p.

The cost for shipping 2 pounds is $1.30.

Part B: The equation, after the reduction of $0.05 in the shipping of per pound is:

c = 0.6p.

What are equations?

Equations are relations between two quantities involving variables raised to multiple powers, making up terms along with numerals.

How to solve the question?

In the question, we are informed that Charlie's Computer Company charges $0.65 per pound to ship computers.

Part A:-

We are asked to write an equation to determine the total cost, c, to ship p pounds of computers.

We know that the total cost equation is designed as:

Total cost = fixed cost + (per unit cost)*(number of units).

Thus, the required equation is:

c = 0 + 0.65p, {Since c is the total cost, the fixed cost is 0, the quantity of computers shipped is p pounds, and per pound cost of shipping is $0.65}

or, c = 0.65p.

The cost for shipping 2 pounds, can be calculated by substituting p = 2 in the above equation.

Thus, c = 0.65*2 = 1.30.

Thus, the cost of shipping 2 pounds is $1.30.

Part B:-

We are asked to write an equation for the total cost, c, to ship p pounds of computers, when the company reduces the cost to ship computers by $0.05 per pound.

Now, the unit cost of shipping one pound of computers is $0.65 - $0.05 = $0.60.

We know that the total cost equation is designed as:

Total cost = fixed cost + (per unit cost)*(number of units).

Thus, the required equation is:

c = 0 + 0.60p, {Since c is the total cost, the fixed cost is 0, the quantity of computers shipped is p pounds, and per pound cost of shipping is $0.60}

or, c = 0.60p.

The length of e rectangle is three times the width. The perimeter of the rectangle is 72 cm. Find the dimensions of the rectangle.

Answers

Answer:

Step-by-step explanation:

Let the width be w. The length is then 3w (length is 3 times its width).

The formula for the perimeter is 2l + 2w (2 times the length + 2 times the width)

So, in our case we have 2(3w) + 2w = 72

                                  6w + 2w = 72

                                  8w = 72   divide both sides by 8

                                  w = 9

So the length = 3w = 3 x 9 = 27

Double check: we have l = 27 and w= 9. (2 x 27) + (2 x 9) = 54 + 18 = 72  Yay!!!

Jack borrows $2,700 at a rate of 8.2% per year. How much simple interest will he owe if it takes 3 months to repay the loan? Round to the nearest cent.

Answers

Answer: $55.35

Step-by-step explanation:

The simple interest on $2700 at a rate of 8.2% per year for 3 months will be $55.35.

What is simple interest?

Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time.

Given that,

Jack borrows $2,700 at a rate of 8.2% per year.

Principle amount P = 2700

Rate of interest = 8.2% per year

Rate of interest per month ⇒ 8.2/12 = 0.683%

The simple interest for the  T time period is given by,

Interest = PRT/100

Interest = (2700 × 0.683 × 3)/100 = $55.35

Hence "The simple interest on $2700 at a rate of 8.2% per year for 3 months will be $55.35".

Standard form equation:Ax + By = C

where A, B and C are constant. x and y are variables.

using y = mx + b

where
