If the area (in square units) of the region under the curve of the function f(x) = 3x − 1 on the interval [a, 4], where a < 4
Goryan [66]

Answer:

  • 8/3
  • -2

Step-by-step explanation:

The integral from a to 4 is ...

\int\limits^4_a {(3x-1)} \, dx =\dfrac{3}{2} (4^2-a^2)-(4-a) = 20+a-\dfrac{3}{2}a^2

We want the value of this to be 12, so we can write ...

  -3/2a^2 +a +20 = 12

  3a^2 -2a -16 = 0 . . . . . subtract the left side and multiply by 2

  (3a -8)(a +2) = 0 . . . . . factor

  a = 8/3 or -2  . . . . . . . .values of a that make the factors zero

The only possible values of a are 8/3 and -2.

8x−6y=1 what is the slope of the line
Zepler [3.9K]

Answer:

m = 4/3

Step-by-step explanation:

Two ways to do this problem.  

Method 1   change the                          Method 2   If a linear equation is in

equation to slope-intercept form            standard form, ax =by = c then

8x - 6y = 1                                                  the slope = -a/b

-6y = -8x + 1                                                 In 8x - 6y = 1  a = 8 and b = -6

y = (-8x)/-6 +1/-6                                          So m = - (8)/-6 = 8/6 = 4/3

m = -8/-6= 4/3

Note:  Method 2 only works if the equation is in standard form.
