Answer:

B'(-2,-6)

Step-by-step explanation:

Hope this helps!!

The co-ordinates of B' after a reflection across the line y = -1 are (-2,-6)

A pair of numbers that use the horizontal and vertical separations from the two reference axes to define the location of a point on a coordinate plane. A coordinate curve is created in two dimensions when one of the coordinates in a point coordinate system is kept constant while the other coordinate is permitted to change.

The coordinate curves may be referred to as coordinate lines if they are actually straight lines. The coordinate axes of Cartesian coordinate systems are lines that are orthogonal to one another. The coordinate curves may be universal curves for different coordinate systems. Curvilinear coordinate systems are those in which some coordinate curves are not lines.

x -co-ordinate of B' = -2

y-co-ordinate of B' = -6

The co-ordinates of B' after a reflection across the line y = -1 are (-2,-6)

Answer:

x = (3 + 8y) / (y - 1)

Step-by-step explanation:

y = (x + 3) / (x - 8)

Make x the subject

y = (x + 3) / (x - 8)

Cross product

y * (x - 8) = (x + 3)

xy - 8y = x + 3

xy - x = 3 + 8y

Factorize the left hand side of the equation

x( y - 1) = 3 + 8y

Divide both sides by (y - 1)

x = (3 + 8y) / (y - 1)

Answer:

15.2 meters

Step-by-step explanation:

50 ÷ 3.3 = 15.15

1 meter= 3.3 feet, so when BASKETBALL The standard width of a high school basketball court is 50 feet. then width is 15.15 meters of the basketball court in meters.

1 meter= 3.3 feet

Given width of high school basketball is 50 feet and1 meter = 3.3 feet.,

We need to find the value of 1 feet.

1 feet= 1meter/3.3

1 feet=0.3030

Now to calculate 50 feet , we need to multiply 50 with 1 feet.

50*0.3030=15.15Meters

Therefore 15.15 meters is the width of the basketball court in meters.

Step-by-step explanation:

180 - 59 - 90 = 31

Answer:

c=15+25x

Step-by-step explanation:

From the information given, you can say that the total amount Tom's Landscaping charges for a job would be equal to the flat fee plus the result of multiplying the charge per hour for the number of hours and this would be:

c=y+25x (1), where:

c is the total cost

y is the flat fee

x is the number of hours

Now, as you know that Tom charged a customer $90 for a job that required 3 hours, you can replace c with 90 and x with 3 and solve for y to find the flat fee:

90=y+25(3)

90=y+75

90-75=y

y=15

Finally, as you know that the flat fee is 15, you can replace this value in (1) to establish the equation that would calculate the total amount that Tom's Landscaping charges for a job that requires x hours of work:

c=15+25x

Step-by-step explanation:

0.333333333×0.3=1

3/10=0.3

The expression (6.4 × 10³) ÷ (3.2 × 10²) can be simplified to 0.2 × 10² in scientific notation.

Scientific Notation is a way of writing down in the easy form of very large or very small numbers.

To evaluate this expression, you can first divide the numerator by the denominator:

(6.4 × 10³) ÷ (3.2 × 10²) = (6.4 / 3.2) × (10³ / 10²)

Next, you can simplify the fraction in the numerator:

(6.4 / 3.2) × (10³ / 10²) = 2 × (10³ / 10²)

Finally, you can simplify the fraction in the exponent:

2 × (10³ / 10²) = 2 × 10¹

2 × 10 = 20 = 0.2 × 10²

Therefore, in scientific notation, the expression (6.4 × 10³) ÷ (3.2 × 10²)  can be written as 0.2 × 10².

Answer:

180 degrees since only two opposite sides are congruent in a rect, which would require you to flip it 180 degrees for it to map onto itself

Answer:  180 degrees

Imagine you had a long and flat rectangle. If we spin it around the center, we can rotate it 180 degrees so it lines up with its original image. The before and after is the same. We say it has rotational symmetry, and the angle of rotation is 180 degrees. This is the smallest rotational angle possible for rectangles that aren't squares.

Answer:

Length = 3 7/8cm

Width  = 2 3/4 cm

Step-by-step explanation

Let the length of the rectangle by L

Let the width be W

If the length of a rectangle is 1 1/8 cm longer than the width, then;

L = W + 1 1/8

L = W +9/8

perimeter of the  rectangle = 2(L+W)

perimeter of the  rectangle = 2(W + 9/8 + W)

13 1/4 = 2(2W + 9/8)

53/4 = 4W + 9/4

4W = 53/4 - 9/4

4W = 44/4

4W = 11

W = 11/4

Hence the width of the rectangle is 11/4 or 2 3/4 cm

Recall that L = W + 9/8

L = 11/4 + 9/8

L = (2(11) + 9)/8

L = 31/8

L = 3 7/8cm

hence the length is 3 7/8 cm

Answer:

Length = 3 7/8cm

Width  = 2 3/4 cm

Answer: 1 hour 15 minutes

Step-by-step explanation:

From the question, we are informed that Laura and Alicia both exercise 5 days a week and that Laura exercises for 30 minutes each day. For the 5 days, she'll exercise for:

= 5 × 30 minutes

= 150 minutes

= 2 hours 30 minutes

Alicia exercises for 45 minutes each day. Fir the 5 days, she'll exercise for:

= 5 × 45 minutes

= 225 minutes

= 3 hours 45 minutes

We then calculate the difference in their exercise per week which will be:

= 3 hours 45 minutes - 2 hours 30 minutes

= 1 hour 15 minutes

Answer:

x = 4

Step-by-step explanation:

3(4x - 7) = 27

distribute the 3

(3 * 4x) + (3 * -7) = 27

12x + (3 * -7) = 27

12x - 21 = 27

add 21 to both sides of the equations

12x - 21 + 21 = 27 + 21

12x = 27 + 21

12x = 48

divide both sides by 12

12x/12 = 48/12

x = 48/12

x = 4/1
