Subtract 49 from both sides
x^2= -49
x= -49 in square root
x=7
the answer to this problem is no.
Answer:
"Susanna starts out slower than Anita but still wins the race."
Step-by-step explanation:
The distance of the race is "5 miles". We can see the "endpoint" of each race's graph and corresponding y value. That is 5 miles.
Now, we look at corresponding "x" value, that is the time it took.
For Susannah, it is 5.5 minutes
For Anita, it is 7 minutes.
So, clearly, Susanna wins the race.
Now, we look at the "slopiness" of each person's line graph. This is the speed at which they were going.
The red line (Susanna) is quite sharper than anita, so her speed (rate) is more. But initially, we can see that the blue line (Anita) was sharper than Susanna but later gradually fell. So we can say:
Susanna started out slower than Anita, but ultimately won.
From the answer choices, last one is right -- "Susanna starts out slower than Anita but still wins the race."

Determine the coordinates of S
Midpoint is calculated as:
Where:
Substitute these values in the above formula:
Multiply through by 2
By direct comparison:
and 
Solving for x2
Solving for y2
Hence, the coordinates of S is:
