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)

What is the slope of the line that passes through the points (1,7) and (-4,-8)?

julia-pushkina [17]

Answer:

The slope of the line that passes through the points (1,7) and (-4,-8) is 3.

Step-by-step explanation:

The equation of a line has the following format.

$y = ax + b$

In which a is the slope.

Passes through the point (1,7)

When $x = 1, y = 7$

$y = ax + b$

$7 = a + b$

Passes through the point (-4, -8)

When $x = -4, y = -8$

$y = ax + b$

$-8 = -4a + b$

We have to solve the following system

$a + b = 7$

$-4a + b = -8$

We want to find a.

From the first equation

$b = 7 - a$

Replacing in the second equation

$-4a + b = -8$

$-4a + 7 - a = -8$

$-5a = -15$

$5a = 15$

$a = \frac{15}{5}$

$a = 3$

The slope of the line that passes through the points (1,7) and (-4,-8) is 3.

If grapes are $1.60 per 1/2 pound, how many pounds can you buy for $64.00?

kondor19780726 [428]

$1.60 = 1/2 a pound
$1.60 x 2 = 1 pound
$3.20 = 1 pound
$64.00 / $3.20 = 20 pounds

You can buy 20 pounds of grapes for $64.00 .
