If the origin is not shaded the answer is C
Answer:
Step-by-step explanation:
11 a. Since she runs 10km in one hour she runs 5km in half an hour and 25km in 2 and a half hours
11b. Since she runs 5 miles in one hour she runs 2.5 miles in half an hour and 12.5 mils in 2 and a half hours
11 c. Since 1.60934 kilometers = 1 mile, Clair ran the farther distance
12 a. 13.20/6 = 2.2 dollars for 1 bowl
12 b. 9/3 = 3 and if he got 3 sets of 3 free bowls he bought 24 pairs of glasses
12 c. If Malcom bought 24 pairs of glasses 24*1.80 = 43.2, so he spent 43.2 dollars on glasses
13 a. 6 to 4 or 6:4
Lets check the first point (0,6)
3*0+4=4 no good
0+6 =6 good
0^2+6 =6 good
6 * (7/6) ^0 =6 good
Lets check the second point (1,7)
3*1+4= we don't care since it didn't work for (0,6)
1+6 =7
1^2+6 =7
6 * (7/6) ^1 =7
Lets check the third point (2,10)
3x+4= we still don't care
2+6 = 8 no good
2^2+6 =10 good
6 * (7/6) ^2 =6 * 49/36 =49/6 no good
f(x) = x^2 +6
