Option fourth "−48; velocity decreases at rate of 48 miles per hour as the time increases" is correct.
<h3>What is the slope?</h3>
The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
We have a function:
v(t) = 352 − 48t
The above function represents the speed of a plane that is landing in the sky.
The function is a linear function.
On comparing with:
y = mx + c
v(t) = -48t + 352
m = -48
-48 is the slope and it representing velocity decreases at rate of 48 miles per hour as the time increases.
Thus, option fourth "−48; velocity decreases at rate of 48 miles per hour as the time increases" is correct.

Answer:
6.8%
Step-by-step explanation:
When you divide this, you get 0.068. This is in decimal form. To change to a percent move the decimal to places to the right 6.8%
Answer:
It would take 4 men 37 hrs and 12 mins to complete the same task.
step-by-step explanation:
Let X be the time the four men would use to complete the task.
From the question, 6 men completed a task in 24 hrs and 48 mins
But
Using ratio and proportion
if more, less divides and if less, more divides.
4 men required more time to complete the task
Hence:
x = 37 hrs 12 mins
The answer would be 6/15+10/15. You get this by finding the common denominator which is 15 by multiplying 3 and 5 by 3 and 2 and 3 by 5
Answer:
Step-by-step explanation:
x - 2 (x - 
) = 2 (4 - x) + 10
x − 2 × 
=2(4−x)+10
x−(−x)=2(4−x)+10
x+x=2(4−x)+10
2x=2(4−x)+10
2x=8−2x+10
2x=−2x+18
2x+2x=18
4x=18
