Step-by-step explanation:
Answer:
4, 1
Step-by-step explanation:
If you take 2, 8 and make it a ratio you get 2 : 8.
Then you turn 2 : 8 into 1 : 4. That is your answer for a mile.
For the other answer, you want to divide 2 by 8.

Answer:
Step-by-step explanation:
In this case we know the composition of f and g is

Thus if we change x by 3 we get

Answer:
y = 3x + C
y = mx + 5
y = 3x + 5
Step-by-step explanation:
A. The standard form for lines with slope = 3 is
y = 3x + C where C is the y-intercept and can be any number
B. The standard form for lines with y-intercept = 5
y = mx + 5 where m is the slope and can be any number
C. The only line with slope = 3 and y-intercept =5
y = 3x + 5
There is only one line because both m and C are given.
The Dolphins football team gained 16 yards on their first play, then lost 11 yards on the next play. Write an addition expression to represent this situation. Find the sum and explain its meaning.
Answer: On the first play, Dolphin's football team gained 16 yards.
On the 2nd play, Dolphin's football team lost 11 yards.
Therefore, the addition expression to represent this situation is:

The sum of this expression is:

Therefore, we can interpret it as: Dolphin's football team gained 5 yards over the 2 plays
