Answer:
Step-by-step explanation:
The above equation is of the form y=mx+c
c is the y intercept so c=2
Answer:
see explanation
Step-by-step explanation:
He wants to buy at least 4 snacks , that is can be more than 4 , so
x + y ≥ 4
He only has $20 , thus total cost must be less than or equal to $20 , so
3x + 2y ≤ 20
Answer:
The speed Alex was going first was 16 mph
Step-by-step explanation:
The distance Alex was walking = 48 mile
The speed with which Alex was walking for the first half of the time = 2 × The speed Alex was walking for the second half of the time
The total time Alex spends on the road = 4 hours
Let x represent the speed with which Alex was walking in miles per hour, (mph), the first half of the time
Therefore, we have;
x × 2 + x/2 × 2 = 48
3·x = 48
∴ x = 48/3 = 16
Therefore, the speed with which Alex was walking in miles per hour, (mph), the first half of the time = x = 16 mph
Alex was going at 16 miles per hour (mph) first.
8^2+3^2= c^2

AC = 8.5 = C
So BD has to be D
