Answer:

A line parallel to the y-axis in the (x, y) coordinate plane is undefined.

Step-by-step explanation:

We know that the slope of a vertical line on a coordinate plane is undefined.

We also know that a line parallel to the y-axis is basically a vertical line.

Therefore, a line parallel to the y-axis in the (x, y) coordinate plane is undefined.

EXAMPLE

For example, considering the two points of a line

(x₁, y₁) = (1, 3)

(x₂, y₂) = (1, 5)

Determining the slope between (1, 3) and (1, 5)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

              =  [5 - 3] / [1 - 1]

               = 2/0

               = ∞ or undefined

Thus, the slope of the line = m = undefined

Thus, the equation of a line parallel to y-axis passing through the points (1, 3) and (1, 5) will be:

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: 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

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)

The earned $440 in interest depositing $5500 for 2 years at 4% rate of interest.

We know simple interest (SI) is given by SI = (p×r×t)/100, where

p = principle, r = rate in percentage, and t = time in years.

Simple interest is often a predetermined percentage of the principle amount borrowed or lent paid or received over a specific time period.

Given, Marsha deposited $5,500 into a savings account 2 years ago at 4% simple interest.

So, p = 5500, r = 4 and t = 2.

Therefore,

SI = (5500×4×2)/100.

SI = 440.

So, Marsha earned $440 in interest.

0.75 * 40

30

divide 40 by 4 and then multiply by 3

40/4

[tex]\frac{3}{4} *\frac{40}{1}[/tex]

the 4 and 40 cancel out

3 * 10 = 30

[tex]\frac{30}{1}[/tex] = 30

For the 1st one, the equations never intersect. There is only 1 case where the lines never intersect and that is when they are parallel. So the 1st one is that they are parallel. A and B are parallel when graphed.

For the 2nd one, the lines are always intersecting. This means that C and D are the same line when graphed.

Answer:

see explanation

Step-by-step explanation:

The solution of equations given graphically is at the point of intersection of the 2 lines.

No solution indicates that there is no point of intersection, thus the graph of A and B are parallel lines which never intersect.

B

Infinitely many solutions indicates that the graph of C and D lie on the same line.

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.

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

x = 4

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.
