Find the slope of the line going through the points (5, 2) and (0, -13).

never [62]

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (5, 2) and (0, -13). Substitute:

$m=\dfrac{-13-2}{0-5}=\dfrac{-15}{-5}=3$

<h3>Answer: slope = 3</h3>

Lin runs 5 laps around a track in 6 minutes how many laps per minute is that

pychu [463]

Lin runs 5 laps around a track in 6 minutes. It is 0.83 laps per minute

Step-by-step explanation:

Simple division will be used to solve the given problem.

We hvae to calculate laps per minute which will be calculated by dividing the number of laps by total time in minutes.

Given

Laps = l =5

Time = t =6 minutes

Then

$Laps\ per\ minute = \frac{l}{t}\\=\frac{5}{6}\\=0.83\ laps\ per\ minute\\$

Evaluate the following expression for n=8 4+(n-2)divided by 3

Anna71 [15]

I think the answer would be 6.

Since n=8,

the equation could be rewritten as 4+(8-2)÷6

There is a rule called PEMDAS

Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

When solving equations, we should follow this rule.

Since there are parenthesis in the equation, we have to solve inside it first. Inside the parenthesis, we see the equation 8-2. 8-2 would equal 6. Then the whole equation would become 4+6÷3. Since division is the next operation in the equation(according to PEMDAS), we divide. 6÷3 would equal 2. Then the equation becomes 4+2. 4+2 would equal 6. Then the answer would be 6. I hope this helped :)
