Answer:
Step-by-step explanation:
f(x) = 3x² -5x - 1
f'(x) =2*3x - 5*1 +0
= 6x - 5
f'(4) = 6*4 - 5
= 24 - 5
= 19
Answer:
11+7x
Step-by-step explanation:
Simplifying
9x + 10 + -2x + 1
Reorder the terms:
10 + 1 + 9x + -2x
Combine like terms: 10 + 1 = 11
11 + 9x + -2x
Combine like terms: 9x + -2x = 7x
11 + 7x
Final result:
11 + 7x

Step-by-step explanation:
Answer:
10 bugs
Step-by-step explanation:
If last month the spider ate 8 bugs, and this month the spider ate 25% more bugs, we can calculate the amount of bugs the spider ate this month finding how much is 25% of 8 bugs, and them we sum this value to the 8 bugs it ate last month.
25% of 8 = 8 * 25 / 100 = 2
Now we know that the spider ate 2 more bugs, so the amount of bugs it ate this month is 8 + 2 = 10 bugs.
We can also solve this problem multiplying directly 8 by 1.25 (1.25 represents the 25% increase in the bug consumption):
8 * 1.25 = 10 bugs.
