Sum means to Add.
So the sum of d and 9 would be d + 9
Lynn age: 7x+2. That's if you wanted an equation.
So if Hugo has saved $10 the first week and $6 for the next 6 weeks the answer would be $46.
you can either add up 6 six times or you can multiple 6 by 6.
6+6+6+6+6+6=36 or 6×6=$36
then you add the $10 from the first week & the $36 from the $6 you saved for 6 weeks to get your final answer of $46.
$36+$10=$46
Answer:
(−∞,4)
Step-by-step explanation:
Explanation:
To determine the interval that f(x) is increasing.
increasing when f'(x)>0f'(x)=−2(x−4)← using chain rule
solve −2(x−4)>0
⇒−2x+8>0
⇒x<4
interval is (−∞,4)
graph{-(x-4)^2-3 [-8.89, 8.89, -4.445, 4.44]}
