At what point on the curve y = 2 + 2ex − 4x is the tangent line parallel to the line 4x − y = 3? (x, y) =

Papessa [141]

Answer:

{ln 4, (2 + 2e^ln 4 − 4 ln 4)} or (1.39, 4.45)

Step-by-step explanation:

From this equation 4x − y = 3

-y = 3 - 4x

then, y = 4x - 3

From line equation y = mx + b

Therefore, the slope is 4

Since the are parallel line, they will have same slope

Finding the derivative of y = 2 + 2e^x − 4x

y = 2 + 2e^x − 4x

y' = 0 + 2e^x - 4

Therefore,

4 = 2e^x - 4

4 = e^x

x = ln 4 = 1.39

To find the y coordinate

y = 2 + 2e^x − 4x

y = 2 + 2e^ln 4 − 4 ln 4

y = 4.45

Hence, they are parallel at point (1.39 and 4.45)

Divide. HELP ASAP PLEASE!!

VashaNatasha [74]

Answer:

The answer to your question is below

Step-by-step explanation:

a) $\frac{s^{2}- 3s - 28 }{s - 7}$

Factor the numerator is a polynomial of the form x² + bx + c

s² - 3s - 28 = (s - 7)( s + 4)

Substitute

$\frac{(s - 7)(s + 4)}{(s - 7)}$

Simplify like terms

Result s + 4

b) $\frac{c^{2} + 5c - 24}{c + 8}$

Factor the numerator is a polynomial of the form x² + bx + c

c² + 5c - 24 = (c + 8)(c - 3)

Substitute

$\frac{(c + 8)(c - 3)}{c + 8}$

Simplify like terms c - 3

Result c - 3
