What is <br> x divided 7 = 3; 20, 21, 22
chubhunter [2.5K]
X/7= 3
⇒ x= 3*7
⇒ x= 21

x/7= 20
⇒ x= 20*7
⇒ x= 140

x/7= 21
⇒ x= 21*7
⇒ x= 147

x/7= 22
⇒ x= 22*7
⇒ x= 154

Hope this helps~

Find the linearization L(x) of the function at a. f(x) = x^4 + 2x^2, a = 1
gregori [183]

The equation of the tangent line at x=1 can be written in point-slope form as

... L(x) = f'(1)(x -1) +f(1)

The derivative is ...

... f'(x) = 4x^3 +4x

so the slope of the tangent line is f'(1) = 4+4 = 8.

The value of the function at x=1 is

... f(1) = 1^4 +2·1^2 = 3

So, your linearization is ...

... L(x) = 8(x -1) +3

or

... L(x) = 8x -5

Find the equation of a line that passes through points (1,8) and (4,4).​
daser333 [38]

Step-by-step explanation: Using the equation, y = mx + b, the slope-intercept form, plug in the values you have and solve for b. (m is the slope.) You have y = -8 and x = 4 and m = 1/2.
