Answer:
1 piece will cost 2 cents
Step-by-step explanation:
If you divide 7.91 by 0.17, you will get 0.021492, and if you round that up you will get 0.02 which is 2 cents. Now if you want to find the price of more pieces, you can just multiply 2 by however the person needs to buy, and write that as money :)))
7/12 is less than 3/4.
Check: 3/4 is same as 9/12. Clearly see that 7/12 is less than 9/12
Answer:
The first statement is true.
Step-by-step explanation:
The function is f(x) = - (x + 6)(x + 2)
⇒ f(x) = - x² - 8x - 12
Now, condition for a function f(x) to be increasing at x = a is f'(a) > 0.
Now, f(x) = - x² - 8x - 12
⇒ f'(x) = -2x - 8 {Differentiating with respect to x}
Now, f'(a) = -2a - 8 {Here a can be any real value}
And, the condition for increasing function at x = a is
- 2a - 8 > 0
⇒ - 2a > 8
⇒ a < - 4
Therefore, the first statement is true i.e. the function is increasing for all real values of x where x < – 4. (Answer)
