Answer: 4!!!!!!!!!!! Or is it 9?
Step-by-step explanation:
2 hours 15 mins = 2 1/4 hours
2 1/4 hours = 25 miles
1 hour = 25 ÷ 2 1/4 = 25 ÷ 9/4 = 25 x 4/9 = 11.1 miles
Answer: 11.1 mph
Answer:
Slope
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
<em>m</em> = slope
<em>b</em> = y-intercept
We are given y = 2x + 3:
We define our variables:
<em>m</em> = 2
<em>b</em> = 3
Therefore, our slope is 2 and our y-intercept is 3.
Answer:
f'(x) = 2x +
Step-by-step explanation:
differentiate using the power rule
( a ) = na
Given
f(x) = x² - + 9 = x² - 4 + 9 , then
f'(x) = 2x + 12 = 2x +
