What is the equation of the line that passes through the point (6, 8) and has a slope 1/2

Answers

Answer:

y=1/2x+5

Step-by-step explanation:

Plug it into the formula for a point and a slope.

(y-(y(subscript 1)))=(m)(x-(x(subscript 1)))

Y-8=1/2(x-6)

Then multiply the 1/2 to the x and -6. After you do that, move everything so that it has y by itself on the left. Your ending should be y=1/2x+5.

Answers

Answer:

Step-by-step explanation:

FG = EH ( being opposite sides of parallelogram)

3z + 8 = 5z - 14

5z - 3z = 8 + 14

2z = 22

z = 11

Now

FG = 3z + 8 = 3 *11 + 8 = 33 + 8 = 41

If the perimeter of a square is 120f+80 inches, what is the length, in inches, of each side of the square?

Answers

Answer:

30f + 20

Step-by-step explanation:

A square has four sides, all of equal length. If we call that side length x, then the perimeter - the total length around the square - is 4x. To find the side length given the perimeter then, we can simply divide the perimeter by 4.

Our perimeter here is 120f + 80, and dividing each term by 4 gives us a side length of 30f + 20.

The solution to the quadratic equation is x = -6 ± 2√7

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

x² + 12x + 25 = 17

Subtracting 17 on both sides , we get

x² + 12x + 8 = 0

And , roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

On simplifying , we get

x = ( -12/2 ) ± √ ( 12 )² - 4 ( 1 ) ( 8 ) / 2

x = -6 ± √ ( 144 - 32 ) / 2

x = -6 ± √112/2

And , the value of x = -6 ± 2√28/2

x = -6 ± 2√7

Hence , the solutions are x = -6 + 2√7 and -6 - 2√7

Which calculation and answer show how to convert 3/12 to a decimal
Plz help ASAP

Answers

Answer:

Its C

Step-by-step explanation:

It is C becuase when converting a fraction to a decimal, you just divide the numerator by the denominator

Basically solve the fraction

3/12=1/4

1/4 is a bencmark so right away you should know that should equal to 0.25 since its a quarter.

Or you can always look it like this

3 is the numerator

the “/“ between is basically ”divided by”

And the 12 is the denominator

Now read the equation in that order

3/12= 3 DIVIDED BY 12

multiply and subtract and do the x y across

Answer:

y = 3/8, x = 7/4

Step-by-step explanation:

x = 2y+1

-7(2y+1) - 2y = -13

-14y - 7 - 2y = -13

-16y - 7 = -13

-16y = -6

y = 3/8

Plug the value for y into one of the equations to solve for x

You are planning the running shoe merchandise levels for your shoe store. Last year, your running shoe sales were down 10% from the previous season. The store had projected sales of 900 pairs of running shoes. Calculate the number of units the 10% sales decline represents.

Answers

Answer:

Step-by-step explanation: by taking 10% off of 900, you get 810; meaning 90 was subtracted

The number of units the 10% sales decline represents is 90

what is percentage?

In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%"

Given here projected sales = 900 but the actual sales is 10% less than this amount , thus actual sales = 900 - 10% of 900

= 900 -( 10/100 )×900

= 900 - 90

= 810

Hence, the number of units the 10% sales decline represents is 900-810 =90

What is the area of triangle AOB? *picture attached* show work also please

Answers

Answer:

The area of the traingle AOB is 30 (Rounded up result)

Step-by-step explanation:

7.8 cm and 10 cm.

10/2= 5 cm

Then Reversed Pitagora's Formula:

Square root of the calc "(7.8^2)-(5^2)" = 60,84 - 25 = 35,84

Then Square root of 35, 84 is 5,98.

5.98 is the height of the triangle AOB

With the height we can calculate the area

We use the formula (B*H)/2

So is (10*5,98)/2, that makes 29,9

Just round up to 30 and that's the area.
