0.78 miles per hour (mph)
Hi there!
f(x) = 2x + 6
Differentiating 2x = 2 (Power rule, dy/dx xⁿ = nxⁿ⁻¹)
Differentiating a constant always equals 0.
Thus:
f'(x) = 2
The answer is 2 can i have brainliest pls
Answer:
2) 1 dozen apple ( 12 apples ) = $4.92
1 apple = $4.92/12
= $0.41
3) distance = speed × time
= 9/10 × 10
= 9 miles
4) 61 minutes = 183 pages
1 minute = 3 pages
5) 8 days = 7 boats
1 day = 7/8 boats
6) speed = distance/ time
= 288/4
= 72 miles/hour
7) 5 cup of flour = 4 cups of sugar
1 cup of flour = 4/5 cup of sugar
You have to think about what y and x can be equal to for you to get 12. (Hint: y is going to be a bigger number than x)
Ex: 3y-5x=5
Think: 3 x 10(y) - 5 x 5(x)= 5
So, y would be 10 and x would be 5.
