<h3><u>Answer:</u></h3>
<h3>-16 : 8 ✓ </h3>
<h3><u>Solution ( step-by-step ): </u></h3>
The temperature changes -16 degrees ( negative because it wents down ) in 8 hours , So to know the chance per hour, We divide the number of degrees by the number of hours. If we call DT the change of Temperature each hour, we have that:
→ DT = -16 degrees/8 hours = -2 degrees / hour ..

We can calculate for the slope of the line using the
formula:
m = (y2 – y1) / (x2 – x1)
From the given values:
m = (4,000 – 10,000) ft / (15 – 0) min
m = -400 ft/min
This means that the altitude is decreasing by 400 ft per
minute.
> The slope is –400 . This means that the helicopter
descends 400 ft each minute.
The easiest way to do this is by graphing the equation. I'll do it:
We see that the y intercept is 11.
Formula for slope-intercept: y = mx + b
mx = slope
b = y-intercept
Now we have y = mx + 11. What's mx? We can find that out from the graph.
Let's find two points: (0,11) (4,3)
Using <span> (y2 - y1)/x2 - x1): We see that the slope is -2.
Now we finish the slope-intercept form and plug it all in:
y = -2x + 11

Answer:
23
Step-by-step explanation:
Answer:
ALL SUCH NUMBERS WHICH ARE GREATER THAN -4 satisfy the given condition.
Step-by-step explanation:
Here, assume such number = m
Now, given :
3 times the number = 3 x ( m) = 3 m
8 less than the given number = m - 8
Now, according to the question:
3 times the number > 8 less than the given number
or, 3 m > m - 8
or, 3m - m > m - 8 + m
or, 2 m > - 8
or, m > - 4
Hence, all SUCH NUMBERS WHICH ARE GREATER THAN -4 satisfy the given condition.
