Kayla Thinks That The Slope Of A Vertical Line Is Undefined, While Joshuaargues That The Slope Of A Vertical

Answers

Answer 1

Answer:

Kayla

Step-by-step explanation:

Vertical lines are always undefined because if your answer has to be divided by zero, the answer is an undefined operation.

Horizontal lines always have the slope of zero!

Answer 2

The slope of a vertical line is undefined.

Kayal is correct.

The rate of change in the table is -6.

The slope of the graph is 3/2.

What is a slope?

The slope of a is the change in the y coordinate with respect to the change in the x coordinate.

We have,

A vertical line means there is no change in the x-coordinate.

i.e slope = change in y-coordinates / change in x-coordinate

slope = change in y-coordinate / 0
slope = undefined

The slope of a vertical line is undefined.

Now,

From the given table we see that there is a change of 1 for the x-values and a change of -6 in the y-values so,

Rate of change in the table:

= change in y values/change in the x values

= -6 / 1

= -6

Now,

Take any two points on the graph such as:

(a, b) = (4, 6) and (c, d) = (-4, -6)

The slope of the graph:

= (d - b) / (c - a)

= -6 - 6 / -4 - 4

= -12 / -8
= 3 / 2

Thus,

The slope of a vertical line is undefined.

Kayal is correct.

The rate of change in the table is -6.

The slope of the graph is 3/2.

Twice the sum of three and a number is 30. Find the number

Answers

9514 1404 393

Answer:

2(x +3) = 3012

Step-by-step explanation:

When x represents the number, "the sum of 3 and a number" is (x+3). Twice that sum is 2(x+3). "Is 30" means this expression is equal to 30:

  2(x +3) = 30 . . . . an equation for the given conditions

__

We can solve this equation by dividing by 2:

  x + 3 = 15

  x = 12 . . . . . . subtract 3

The number is 12.

2. What is the x-intercept of the line
5x – 3y = 15? Write your answer as an ordered

Answers

Answer:

The x-intercept of the line is (3,0)

Step-by-step explanation:

5x - 3y = 15

5x - 3(0) = 15

5x - 0 = 15

(add 0 on both sides the cancel out -0)

5x = 15

(divide by 5)

x = 3

so the x-intercept is (3,0)

angles a and b are vertical angles. If mA = (5x – 24)° and m B = (3x + 24),
then find the value of x.

Answers

Answer:

The correct answer is x = 24.

Step-by-step explanation:

To solve this problem, we must remember that vertical angles have the same measure.  This lets us set up the following equation:

m<a = m<b

If we substitute their values, we get the following:

5x - 24 = 3x + 24

To solve this equation, we can first subtract 3x from both sides of the equation.

2x - 24 = 24

Next, we can add 24 to both sides of the equation.

2x = 48

Finally, we can divide both sides of the equation by 2.

x = 24

Therefore, the answer is x = 24.

Rebecca’s boss pays her time and a half for overtime work. If her regular wage is $13.50 per hour, what is her overtime rate?

Answers

Answer: 20.25

Step-by-step explanation: Rebecca can expect to be making her regular 13.50 an hour, however once time and a half hits she’s looking at taking her 13.50 and dividing it by 2. So 13.50 divided by two is 6.75. You then take that 6.75 and add it on top of her regular 13.50 hourly. Putting you at 20.25 for time and a half.
