14 POINTS 14 Points 14 points

Given:

The pair of end points: (3,-8) and (3,-1).

To find:

Whether the given pair of endpoints lies on the same horizontal or vertical line.

Solution:

If the x-coordinates of pair of endpoints are same, then the pair of endpoints lies on the same vertical.

If the y-coordinates of pair of endpoints are same, then the pair of endpoints lies on the same horizontal.

The given endpoints are (3,-8) and (3,-1).

From the given endpoints, it is clear that the x-coordinates of the endpoints are same. So, the given endpoints lies on the same vertical line.

The length of the line segment that joins the pair of points is

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]D=\sqrt{(3-3)^2+(-1-(-8))^2}[/tex]

[tex]D=\sqrt{(0)^2+(-1+8)^2}[/tex]

[tex]D=\sqrt{(7)^2}[/tex]

[tex]D=7[/tex]

Therefore, the given endpoints lies on the same vertical line and the length of the line segment is 7 units.

Answer:

5.8cm or 58mm

Step-by-step explanation:

Answer: 17

Step-by-step explanation:

We can tell that for every 2 changes in X there is 8 points lost in y

meaning that if we do 8 /2 we get 4

Every 1 change in x there is 4 points of change in Y

so if (3,5) Then (0,17)

17 - 5 = 12 And 3-0 = 3 So for 3 points of change for Xthere were 12 points of change for Y so this is right

Answer:

2 cards per dollar

$0.50 per card

$6 per dozen cards

Step-by-step explanation:

The unit rate of greeting if a store sells 24 greeting cards for $12 is $0.5, so option $0.50 per card is correct.

Unit rate means the amount of rate for the unit quantity of some things, for example, if you buy 1 kg apple for $2 then the unit rate of apple is $2.

Given:

The selling price of 24 greetings =$12,

The unit rate, of a greeting, is =  The selling price of 24 greetings / no of greetings

The unit rate = 12 / 24

The unit rate = $0.5

Therefore, the unit rate of greeting if a store sells 24 greeting cards for $12 is $0.5.

The statement that is false is:

"The variables x and y can be multiplied together"

The general linear equation is given by:

y = a*x +b

Where a is the slope and b is the y-intercept.

The statement that is evidently false about the above general equation is:

"The variables x and y can be multiplied together"

y depends linearly on x, so these variables can't be multiplied together.

An equation is formed of two equal expressions. An equation to relate the number of pounds of cheese used, y, to the number of pizzas made, x is y=0.5x.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given that Pizza Palace uses 0.5 pounds of cheese on each large pizza it makes. Therefore, an equation to relate the number of pounds of cheese used, y, to the number of pizzas made, x can be written as,

Number of pounds of cheese=Amount of cheese used per pizza × Number of pizzas

y = 0.5 pounds × x

y = 0.5x

Hence, an equation to relate the number of pounds of cheese used, y, to the number of pizzas made, x is y=0.5x.

Answer:

8000

Step-by-step explanation:

I did a simple way, I divided 4800 by 3 and got 1600, then multiplied 1600 by 5. Because 2x5 =10 (or 100%)

Answer:

x = 8000

Step-by-step explanation:

here's your solution

=> it is given that 60% of some unknown

number is 4800

=> now, let the unknown number be X

=> so, 60/100*X = 4800

=> X = 4800*100/60

=> X = 8000

Answer:

$46875.

Step-by-step explanation:

We have been given that Dr. Drake buys a sailboat for 125000. He borrows the money at an APR of 7.5% for five years.

We will find total interest after 5 years by using simple interest formula

A=P(1=rT), where,

A= Amount after T years.

P= Principal amount.

r= The annual interest rate (in decimal form).

T= Time in years.

_______________________________

First of all we will convert our given interest rate from percent to decimal form.

7.5 precent= 0.075

________________________________

Now let us substitute our given values in above formula.

A=125,000 (1+(0.075 x 5))

A=125,000 (1+0.375)

A=125,000 (1.375)

A=171875

To find the amount of total interest we will subtract principal amount from 171875.

Total amount of interest= 171875 - 125000

Total Amount of interest= 46875

Therefore, the total interest after 5 years will be $46875.

Answer:

(x² - 7)(x² - 4)

Step-by-step explanation:

We can actually factor this the same way we would solve a normal quadratic equation.  We will end up with the factored terms have squares of x instead of just x.

x⁴ - 11x² + 28

= x⁴ - 4x² - 7x² + 28

= x²(x² - 4) - 7(x² - 4)

= (x² - 7)(x² - 4)

Answer:

1) x=5

2) x=72

Step-by-step explanation:

errrrrrr being behind on algebra is worrying but what's really worrying is that this is geometry.

but ye you it has an x in it

1) form a ratio out of the bottom sides

2:6=1:3

so x=5

2) make another ratio:

12:72=1:6

x=72

Answer:

x = -1 and 2

Step-by-step explanation:

If f(x) = 2X ^2- X-6 and g(x) = x2 - 4, we are to find x if f(x) = g(x)

2X ^2- X-6  = x^2 - 4,

Collect like terms

2x²-x²-x-6+4= 0

x²-x-2 = 0

Factorize;

x²-2x+x-2 = 0

x(x-2)+1(x-2) = 0

(x+1)(x-2) = 0

x+1 = 0 and x-2 = 0

x = -1 and 2

Hence the value of x are -1 and 2

Answer:

≈ 15 ft

Step-by-step explanation:

There is a right triangle formed by the ground, the building and the ladder.

The ground and the height the ladder is up the wall are the legs and the ladder is the hypotenuse.

let x be the distance from the base of the building to the bottom of the ladder.

Using Pythagoras' identity in the right triangle

x² + 26² = 30²

x² + 676 = 900 ( subtract 676 from both sides )

x² = 224 ( take the square root of both sides )

x = [tex]\sqrt{224}[/tex] ≈ 15 ft ( to the nearest foot )

Answer:

2√2

Step-by-step explanation:

√8 can be simplified to √(4)(2) , since 4 x 2 still equals 8. But now, 4 is a perfect sqaure, and whenever we get a perfect sqaure, we divided it by its root and put that number on the outside.

For ex: √32 = √(16)(2), since 16 x 2 = 32. 16 is a perfect sqaure, so we take its root and put it on the outside 4√2 ,

Now with this one, we'll do the same thing: √(4)(2) = 2√2
