Kalesha is purchasing a laptop. The original price of the laptop is $900. The store is offering 10% off on all computers. Kalesha has a $100 gift card. How should Kalesha determine the amount she will pay for her computer? Subtract $100, then take 10% off. Kalesha will pay .

Answer: She will pay $ 720 for the computer.

Step-by-step explanation:

Since, the cost price of the laptop = $ 900,

Also, after getting the $ 100 gift card,

The new price of the laptop = $ 900 - $ 100 = $ 800

According to the question,

The store is offering 10% off on all computers.

The final price of the laptop = 800 - 10% of 800

= 800 - 80

= $ 720,

Hence, $ 720 will be paid for the laptop.

QUESTION POSTED AT 28/02/2020 - 05:22 AM

The lengths of two sides of a triangle are shown below: Side 1: 3x^2 − 2x − 1 Side 2: 9x + 2x^2 − 3 The perimeter of the triangle is 5x^3 + 4x^2 − x − 3. Part A: What is the total length of the two sides, 1 and 2, of the triangle? (4 points) Part B: What is the length of the third side of the triangle? (4 points) Part C: Do the answers for Part A and Part B show that the polynomials are closed under addition and subtraction? Justify your answer. (2 points)

Part A : add side 1 to side 2
8x^2 - 5x - 2 + 7x - x^2 + 3 ....combine like terms
7x^2 + 2x + 1 <=== total of side 1 + side 2

part B : since perimeter is the sum of all sides, we can find the third side by subtracting the sum of the 2 sides (from part A) from the perimeter.
4x^3 - 3x^2 + 2x - 6 - (7x^2 + 2x + 1)...distribute thru the parenthesis
4x^3 - 3x^2 + 2x - 6 - 7x^2 - 2x - 1 =....combine like terms
4x^3 - 11x^2 - 7 <===length of 3rd side

part C : Polynomials are closed under addition and subtraction because when adding/subtracting polynomials, the result is another polynomial.

1. solve each equation by graphing the related function. If the equation has no real number solutions, write no solution x^2+7=0 2. solve each equation by graphing the related function. If the equation has no real number solutions, write no solution 3x^2=0 3. solve each equation by graphing the related function. If the equation has no real number solutions, write no solution 1/4x^2-4=0

Answer:

We have to find the number of solutions of each of the following equations by observing their graphs.

We know that the number of real solutions are the number of times the graph touches the x-axis. i.e. the point at which the function is zero.

1)

x^2+7=0

Clearly this graph has no real solutions.

Also we can see from the equation that the function takes no real value such that the function is zero.

since,

x^2\geq 0\\\\x^2+7>0

Hence, it has no real solution.

2)

3x^2=0

This graph has one real solution i.e. 0 with multiplicity 2.

Also it could be seen as:

3x^2=0\\\\x=0,0

are the possible solution of the equation.

Hence, the function has one real solution with multiplicity 2.

3)

\dfrac{1}{4}x^2-4=0

From the graph of this function we see that it has 2 real solutions i.e. 4 and -4.

( Also it could be seen as:

\dfrac{1}{4}x^2=4\\\\x^2=16\\\\x=\pm4 )

For the equation below, x is the input and y is the output. y = -4x 3 if the input is -8, then the output is .

From this we know that x = -8
So all we need to do is plug -8 into the equation everywhere there is an x

So y = -4 * -8 + 3

y = 32 + 3

So y is equal to 35, and since y is the output, the output is 35

QUESTION POSTED AT 28/02/2020 - 03:38 AM

Find the slope, if it exsists, of the line containing the pair points, (5,-4) and (8,-9)

To find the slope between 2 points we will use the slop equation

(Y - y)/(X - x)

What this means is that the y part of the first point minus the y part of the second point all divided by the x part of the first point minus the x part of the second point is the slope

So (-4 - -9)/(5 - 8) is the slope

To simplify

-4 minus -9 is 5
And 5 minus 8 is -3

So the slope is 5/-3

Which is -5/3 (negative five thirds)

Feel free to ask questions if you are still confused.
