Step-by-step explanation:
you know by using the x and y coordinates of the point in the equations and see, if both equations are still true.
if yes, it was a solution, and if just only one is false, then it was not a solution.
(3, -2) in
y + 4x = 10
5x - y = 13
so,
-2 + 4×3 = 10
-2 + 12 = 10
10 = 10 true
5×3 - (-2) = 13
15 + 2 = 13
17 = 13 false
so, it was NOT a solution.
Answer:
41/12
Step-by-step explanation:
3 x 12 = 36 then you add 5 to get 41.
Answer:
a) Junnie walked farther than Maurice
b) Junnie walked .62 miles farther than Maurice
Step-by-step explanation: Because speed times time equals distance, to find how far each person traveled you multiply their speed and time.
Distance=speed×time
Junnie:
2.5hrs×3.2mph=8 miles
Maurice:
1.8hrs×4.1mph=7.38 miles
8-7.38=.62 (the difference between the two)
