Answer:

write the given equation in a standard form

6x - 2y = 6

-2y = -6x + 6

y = 3x - 3

m = 3

if the lines are perpendicular to each other the product of their gradient is equal to -1

m1 × m2 = -1

3 × m = -1

3m = -1

m = -1/3

y - y1 = m(x - x1 )

y - (-1) = -1/3 ( x - (-3) )

y + 1 = -1/3 (x + 3 )

y + 1 = -1/3x - 1

y = -1/3x - 1 + 1

y = -1/3x

Desmos is a free graphing calculator.

Answer:

length = 8 yds

width = 5.5 yds

Step-by-step explanation:

Area of rectangle = l * w

w = width

length = 2w - 3

Substitute l with 2w - 3:

(2w - 3)*w = 44

2w² - 3w = 44

2w² - 3w - 44 = 0

Solve for w (AC method):

2w² + 8w - 11w - 44 = 0

2w(w + 4) - 11(w + 4) = 0

(2w - 11)(w + 4) = 0

w = 5.5 or w = -4

note: length cannot be negative, so w = 5.5 yds

Substitute w with 5.5 in either equation:

5.5 * l = 44 yds²

l = 44/5.5 = 8 yds

or

l = 2(5.5) - 3

l = 11 - 3 = 8 yds

Step-by-step explanation:

Applying the alternate interior angles theorem, the measure of angle FBC is determined as: 67°.

If two angles are alternate interior angles formed along a transversal on two parallel lines, then their measures are congruent or the same.

Angles on a straight line are angles that lie along a straight line, and the sum of the angles equals 180 degrees.

Given the following:

m∠BFC = 75°

m∠GFC = 38°

∠EFB, ∠BFC,  and ∠GFC are angles on a straight line, therefore:

m∠EFB = 180 - m∠BFC - m∠GFC

Plug in the values

m∠EFB = 180 - 75 - 38

m∠EFB = 67°

Find the measure of angle FBC:

Angles FBC and EFB are alternate interior angles, therefore:

m∠FBC = m∠EFB = 67° [alternate interior angles theorem]

m∠FBC = 67°

In summary, using the alternate interior angles theorem, the measure of angle FBC is determined as: 67°.

Answer:

Step-by-step explanation:

factors of 54 = 1, 2, 3, 6, 9, 18, 27, 54

factors of 27 = 1, 3, 9, 27

The greatest factor that exactly divides both 54 and 27 is  27 because they both have it as a factor.

The aggregate volume of the two rectangular prisms is 330 cubic cm.

The base's area multiplied by the height gives the rectangular prism its volume. So the formula for a rectangular prism's volume is as follows. Using cubic units, the volume of a rectangular prism = length × breadth × height

The volume is going to be the addition of two volumes.

We are going to divide the shape into two.

Volume = length × breadth × height

Section A and section B

Volume = length × breadth × height

Volume of section A is = 2 × 10 × 9

Volume of section A = 180 cm³

Volume = length × breadth × height

Volume of section B is = 3 × 5 × 10

Volume of section B = 150cm³

Total volume = volume of section A + volume of section B

Total volume = 180cm³ + 150cm³

Total volume = 330cm³

(B) The price of one adult ticket is $4 and the price of one student ticket is $9.

What is system of equations?

A set of one or more equations involving numerous variables is referred to as a system of equations. The variable mappings that satisfy all component equations are the solutions to systems of equations, or the points where the components of these equations intersect.

Given:

Juan's school is selling tickets to the annual talent show.

On the first day of ticket sales the school sold 6 adult tickets and 3 student tickets for a total of $51.

The school took in $90 on the second day by selling 9 adult tickets and 6 student tickets.

Let A be the number of adult tickets sold.

S be the number of students ticket sold.

⇒ 6A + 3S = $51            ..(1)

9A + 6S = $90              ..(2)

Multiply first equation by (2)

12A + 6S = $102            ..(3)

Subtract equation (2) and (3)

   12A + 6S = $102

-   9A + 6S = $90

________________

   3A        = 12

⇒ A = $4

Plug A = 4 in equation (1)

6(4) + 3S = $51

24 + 3S = $51

3S = $51 - $24

3S = $27

S = $9

Hence,

(A)  The system of equations is,

6A + 3S = $51          

9A + 6S = $90

A % is a number without dimensions and without a standard measurement.

For instance, you would have received a 75% grade if you answered 75 out of 100 questions correctly on a test (75/100).

So, percent of goals Amanda achieved:

Answer:

The first expression, (5^2*x^6*y^(-7))(5*x^0*y^28)

Step-by-step explanation:

Basically, add up the exponents for each unique base. We have two exponents with bases of 5 in this expression, 5^2 and 5 (which is equal to 5^1). Add the exponents together to get 3, so you have 5^3 = 125.

Add up the exponents for bases of x this time. We have x^6 and x^0. 6 + 0 = 6, so we have x^6.

Finally add up the exponents for bases of y. We have y^28 + y^(-7) = 28 + (-7) = 21, so we have y^21.
