Step-by-step explanation:

how do i calculate slope?​

Answers

Answer:

In order to calculate the slope, you'll need 2 ordered pairs (x, y).

The formula for calculating the slope is:

[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

where m = slope

(x1, y1) = first ordered pair

(x2, y2) = second ordered pair

Regardless of which values for the (x1, y1) and (x2, y2) you choose, you would still end up with the same slope (as long as it's done correctly).

As an example, let's say you have the following set of points:

(2, 4) (8, 1)

Let (x1, y1) =  (2, 4)

     (x2, y2) = (8, 1)

Plug these values into the slope formula:

[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

[tex]m = \frac{1 - 4}{8 - 2} = \frac{-3}{6} = -\frac{1}{2}[/tex]

Therefore, the slope of the line is - 1/2.

To prove that you'll end up with the same value for the slope:

This time, let (x1, y1) =  (8, 1)

                     (x2, y2) = (2, 4)

[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

[tex]m = \frac{4 - 1}{2 - 8} = \frac{3}{-6} = - \frac{1}{2}[/tex]

Therefore, the value of the slope is still -1/2.

2. Mary answered 6 questions correctly on her Biology test.
She answered 20% of the questions correctly. In total, how
many questions were on the Biology test?

Answers

Answer:

60

Step-by-step explanation:

if 6 questions is 20 percent, that means every 3 questions should be 10 percent. 60÷3=20

Answer:

The Answer is 30 questions in total.

Step-by-step explanation:

1. The first thing you would want to do is to break down this question.

For every 6 questions, this is 20% of the test done.

2. You now would want to divide 100% (the full amount on the test) by 20%.

100%/20% = 5

3. Now, multiply both to get your answer.

6·5= 30

20%x5= 100%.

Therefore, the total amount of questions on the test is 30 questions.

18. You have no more than $60 to spend. You want a drink that costs $1.50 including tax, and you want to buy a
pair of pants, which will have 4% sales tax.

a.) What is the inequality that represents the amount of money you have to spend?

b.) Given that you can spend no more than $60, what is the most a pair of pants could cost?

Answers

Answer:

a. pants + tax + drink ≤ 60 b. $56.16

Step-by-step explanation:

60-1.5 = 58.5 = money left for pants+tax

58.5/100 = 0.585 = 1%

0.585x 4= $2.34 = highest possible tax

58.5 - 2.34 = $56.16 most

pants + tax + drink ≤ 60

Identify the function shown in this graph.
A.y=-x+3
B. y=-5x + 3
C. y=-5x-3
D. y = 5x - 3

Answers

B:-5x+3 u can find the answer by using desmos or Symbolab graphing calculator
Using two points on the graph, we can determine the slope.

Let (x1, y1) = (0, 3)
(x2, y2) = (1, -2)

Use the slope formula and substitute the values:

m = (y2 - y1)/(x2 - x1)
m = (-2 - 3)/(1 - 0)
m = -5/1 or -5.

Therefore, the slope (m) = -5.

The y-intercept (b) is the point on the graph where it crosses the y-axis, and has coordinates (0, b). Looking at the graph, the y-intercept occurs at (0, 3). Therefore, the y-intercept (b) = 3.

Therefore, the linear function of the graph is y = -5x + 3.

The correct answer is B: y = -5x + 3.

Answers

Answer:

Surface area: 277.59 in^2

Volume: 434.89 in^3

Step-by-step explanation:

Radius = C/(2*pi)

29.5/3.14 = 9.39

Radius = 9.39/2 = 4.7 in

A = 4 pi r^2

A = (4) (3.14) (4.7)^2

A = 277.59 in^2

Volume = (4/3) (pi)(r)^3

(4/3)(3.14)(4.7)^3

Surface area: [tex]277.59[/tex] in^[tex]2[/tex]

70 degrees

explanation:
first, it’s important to remember that all angles of a triangle equal 180 degrees. so, subtract 50 from 180 = 130. that means that the last two angles combined equal 130. next, it’s important to remember that a straight line is equal to 180 degrees. since you know that 120 out of that 180 degrees is shown, 180-120 = 60. that means that the bottom angle of the triangle is 60. 60+50 = 110. 180-110= 70. so, that last angle is equal to 70 degrees. hope this helped!!
