Suppose y varies directly with x. If y = 6 when x = 2, find x when y = 12.
igomit [66]

Answer:

x = 4 when y = 12

Step-by-step explanation:

The ratio of y to x is 6:2. If you multiply either one of them, you must do the same to the remaining number. So, when you multiply 6 by 2 to get 12, you must also multiply 2 by 2 to keep the ratio equal and the same. 2x2 = 4, so x=4 when y=12. Hope this helped! Good luck with other math problems :)

Rebecca must complete 15 hours of volunteer work. She does 3 hours each day. Write a linear equation in slope-intercept form to
ValentinkaMS [17]

Answer:

y = 15 hour - 3 hours/day x days

y = 15 - 3x

y-intercept = 15 - 3(0)= 15 which is the amount of volunteer hours she must complete at day 0.

0 = 15 - 3x

3x = 15

x = 5 (Number of days she would have to volunteer)

Equation: y = 15- 3x

Consider the function f(x)=x3+4x2+2. find the points where the tangent line is horizontal.
lions [1.4K]
Thinking about the graph of f(x), the rate of change is zero whenever there is an extremum.

First, differentiate f(x)

f'(x)=3x^2+8x

Next, find the zeros of f'(x) by factoring.

x(3x+8)=0  \\ x= \frac{-8}{3},x=0

Now, we substitute these x-values into the original equation to find the coordinates.
