If you want to decrease something by 70%, it is equivalent to saying you want to reduce it to (100-70) = 30% of its value. Since 30% is equal to 0.3, the single multiplier to use to decrease something's value by 70% is 0.3.
The general rule would be to subtract the % to decrease (like 70%) by from 100%, and convert to decimal form. This would give the single multiplier.
First find the secant line. The slope of the secant line through
(when
) and
(when
) is the average rate of change of
over the interval
:
The tangent line to
will have a slope determined by the derivative:
Both the secant and tangent will have the same slope when
, or when
.
Answer:
r = 28 - p
p r
10 18
12 16
14 14
16 12
Step-by-step explanation:
We have the highest number of points Sidney has scored in a basketball game is 28.
We have to "r" the number of points that he needs to score and "p" are the points that he has already scored and the sum of these would be 28, that is, the total record.
So the equation would be
p + r = 28
we solve for "r" and we are left with:
r = 28 - p
Now, to fill the table it is missing when p = 14 and when p = 16
r = 28 - 14 = 14
r = 28 - 16 = 12
Therefore the complete table would be:
p r
10 18
12 16
14 14
16 12
Answer:
Alexis: 2.5x
Gary: x
James: x + 18
Total: (2.5x) + (x) + (x + 18)
= 4.5x + 18
Bonus:
4.5x + 18 = 1206
4.5x = 1188
x = 264
Alexis: 2.5(264) = 660
Gary: 264
James: 264 + 18 = 282
