1. Put the data in order (Least to Greatest.)
14, 18, 20, 28, 36, 58, 71

2. Multiple by 17.
238, 306, 340, 476, 612, 986, 1207

3. Find the Median.
Because this equation is odd, your median will end up right in the middle of the data. Meaning 476 is the Median.

You can check your answer by taking the surrounding two numbers and doing 340+612/2=476.

Reminder this way of solving is for odd equations like yours. :)

Step 1: Assign variable for the unknown that you need to find.

$d_w \; \rightarrow \; Distance \; you \; traveled \; by \; walk \; in \; miles \\ d_c \; \rightarrow \; Distance \; traveled \; by \; your \; friend \; using \; bicycle \; in \; miles \\ t \; \rightarrow \; Time \; Taken \; in \; hours$

Step 2: List the given details

Distance between you and your friend is 12 miles. It means the total distance traveled by you by walk and your friend using bicycle when both travel towards each other to meet in 't' hours

Equation 1:

$d_w+d_c=12$

Your Walking rate and your friends Cycling rate is given below:

$r_w=4mph\\r_c=11mph$

Step 3: Set up an equation using the relationship between distance, time and rate.

$Distance=Rate \times Time$

$d_w=r_w \times t=4t \\\\ d_c = r_c \times t = 11t$

Substituting the above in equation 1

$4t+11t=12 \\ Combining \; Like \; Terms \\\\ 15t=12 \\ Dividing \; 15 \; on \; both \; sides \\\\ 15t \div 15=12 \div 15 \\\\ t=0.8 hours$

Distance traveled by you by walking from home and distance travelled by your friend in cycle in 0.8 hours is given below:

$d_w=4t=4(0.8)=3.2miles \\\\ d_c=11t=11(0.8)=8.8miles$

Please help!! also please explain I would like to understand.

Answer:

A

Step-by-step explanation:

First, put this equation in slope intercept form.

$y=mx+b$

Where m is the slope and b is the y intercept.

$y+1>2(x-1) \\ \\ y+1>2x-2 \\ \\ y>2x-3$

Since it's greater than, the solution set is above the line, effectively eliminating graph D.

Now we should graph it.

We can see that the point $(2,1)$ is on the graph, and only Graph A has that point. Therefore, Graph A is the correct graph.
