Answer:

x=3, y=-2

Step-by-step explanation:

If 2x-4y=14, then we know that 2x=14+4y.  This means that x=7+2y.  If we substitute this into the next equation we get: 3y+(35+10y)=9.  This means that we have 35+13y=9.  If we subtract 35 from both sides we get 13y=-26.  This means y=-2. If you subsitute this in the first equation, we have 2x--8=14.  -- means + so you do 2x+8=14.  This means that x=3.

btw this is my first answer so sorry if its bad.

Step-by-step explanation:

Answer:

We conclude that the area of the right triangle is:

[tex]A\:=p^2-2p-3[/tex]

Hence, option A is correct.          

Step-by-step explanation:

From the given right-angled triangle,

Using the formula to determine the area of the right-angled triangle

Area of the right triangle A = 1/2 × Base × Perpendicular

                                            [tex]=\frac{1}{2}\left(p+1\right)\left(2p-6\right)[/tex]

Factor 2p-6: 2(p-3)

                                             [tex]=\frac{\left(p+1\right)\times \:2\left(p-3\right)}{2}[/tex]  

Divide the number: 2/2 = 1

                                              [tex]=\left(p+1\right)\left(p-3\right)[/tex]

[tex]\mathrm{Apply\:FOIL\:method}:\quad \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd[/tex]

                                               [tex]=pp+p\left(-3\right)+1\cdot \:p+1\cdot \left(-3\right)[/tex]

                                               [tex]=pp-3p+1\cdot \:p-1\cdot \:3[/tex]

                                                [tex]=p^2-2p-3[/tex]

Therefore, we conclude that the area of the right triangle is:

[tex]A\:=p^2-2p-3[/tex]

Hence, option A is correct.

Equality Properties

Step-by-step explanation:

Step 1: Define

5 - 7(2 - x) = 31 - 4(2x - 5)

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that 19 does indeed equal 19.

∴ x = 4 is the solution to the equation.

Step-by-step explanation:

so the shape gonna be soo long that I wasted yo ur time

The y -intercept in this situation mean that Jerry was given $75 for his birthday

The equation below is a linear equation.

y = 50x + 75

A linear equation is an equation that has a single variable raised to the power of 1. 50x is raised to the power of 1

75 represents the constant. This is the money he deposited in the account. 75 is the y-intercept. The y-intercept is the value of the line y when it crosses the y-axis

50x is the slope of the line. - 50 is the amount he puts in every month and x represents month.

The slope of a line also known as the gradient of the line determines the steepness and direction of a line. If the slope coefficient is less than zero, the slope is negative and it would decline from left to right

y is the dependent variable. It is the total amount he would have at the end of each month.  y depends on the constant term (75), the number of months(x) and the amount he deposits every month (50)

at the end of :

one month, he would have : 50(1) + 75 = 125

two months, he would have : 50(2) + 75 = 175

Answer:d

Step-by-step explanation:

Answer:

24/2 slices

= 12/1

Step-by-step explanation:

Total slices of pizza = 8

Anna and Jose ate = 5

Slices of pizza remaining = 3

Zach and Sarah came over and Anna split the remaining slices evenly between them

That's is, 3 slices of pizza divided by 2 people

= 3/2

= 1 1/2 slices each

Each of Zach and Sarah ate 3/2 slices of pizza

fraction of the original pizza that Zach and Sarah each ate

= 3/2 of 8

= 3/2 × 8

= 24/2

= 12/1

Answer: A. The modes differ by 40 and the ranges differ by 40.

Step-by-step explanation:

The required, modes differ by 40 and the ranges differ by 40. Option A is correct.

To compare the modes and ranges of the given data, let's first find the modes and ranges.

Last Summer:

140, 220, 190, 180, 190

This Summer:

150, 170, 150, 190, 180

The mode is the value that appears most frequently in a dataset, while the range is the difference between the maximum and minimum values in a dataset.

The modes are as follows:
Last summer: The mode is 190 since it appears twice, more frequently than any other value.
This summer: The mode is 150 since it appears twice, more frequently than any other value.

The ranges are as follows:
Last summer: The range is 220 - 140 = 80.
This summer: The range is 190 - 150 = 40.

Now, let's compare the modes to the ranges:

Statement: The modes differ by 40 and the ranges differ by 40. Since the modes differ by 40 and the ranges differ by 40, the statement is true.

Therefore, the correct statement is:

A. The modes differ by 40 and the ranges differ by 40.

Answer:

if a=5 and b=7 so (a+b)=(5+7)=12

(a-b)=5-7= -2

Answer:

(a+b) =12

(a-b) =. - 2

Step-by-step explanation:

You will put the numbers given as a=5 and b=6

In to the value of (a+b) and (a-b)

So it will be

*(a+b) =(5+7)

=(12)

*(a-b) =(5-7)

=(-2)

Answer: The dividend yield on Stock A = 0.04

Step-by-step explanation:

Given: quarterly dividend = $0.15 per share

Annual dividend per share = 4 x 0.15 = $0.6  [1 year = 4 quarters]

Stock's price per share = $0.15

The computation of dividend is given by :-

Dividend yield = (annual dividend per share) divided by (the stock's price per share).

Here, Dividend yield = (0.6) ÷ 15 =  0.04

Hence, the dividend yield on Stock A = 0.04

If I remember correctly, the answer is (1, 31).

Answer:

10 inches.

Step-by-step explanation:

One stack has boxes that are 2 inches high, then the height of this stack can be only multiples of 2 inches.

The other stack has boxes that are 5 inches high, then the height of this stack can be only multiples of 5 inches.

The height of both stacks will be the same for all the common multiples of 2 and 5.

Because 2 and 5 are prime numbers, all the common multiples between 2 and 5 will be direct products of these two numbers.

Like 2*5 = 10

is both a multiple of 2 and 5 (is the first common multiple)

Then we can use stacks of 10 inches.

Such that, for the stack where each box is 2 inches high, we need:

10in/2in = 5

5 boxes.

And for the stack where each box is 5 inches high, we will need:

10in/5in = 2

2 boxes.
