You can spend at most $21 on fruit. Blueberries cost $4 per pound, and strawberries cost $3 per pound. You need at least 3 pound

Juliette [100K]

Answer:

<h2>a. The system of linear inequalities is $x + y \geq 3$ and $4x + 3y \leq 21$ .</h2><h2>b. The solution is given in the figure.</h2><h2>c. The given scenario can happen.</h2>

Step-by-step explanation:

Let, I will buy x pounds Blueberries and y pounds Strawberries.

I need to collect at least 3 pounds of fruits.

Hence, $x + y \geq 3$ .

It also given that I can not spend more than $21, that is $4x + 3y \leq 21$ .

If I will buy 4 pound Blueberries and 1 pound Strawberry, then x = 4 and y = 1.

Now, 4 + 1 = 5 > 3. First inequality is satisfied.

$4x + 3y = 4\times4 + 3\times1 = 16 + 3 = 19 \leq 21$ , Second inequality is also satisfied.

Solve the differential equation. y' + 5xey = 0.

galben [10]

Answer:

The solution is $y = - ln(\frac{5}{2}x^{2} + C)$

Step-by-step explanation:

To solve the differential equation, we will find $y$

From the given equation, y' + 5xey = 0.

That is, $y' + 5xe^{y} = 0$

This can be written as

$\frac{dy}{dx} + 5xe^{y} = 0$

Then,

$\frac{dy}{dx} = - 5xe^{y}$

$\frac{dy}{e^{y}} = - 5x dx$

Then, we integrate both sides

$\int {\frac{dy}{e^{y}}} =\int {- 5x dx}$

$\int {e^{-y}dy }} =\int {- 5x dx}$

Then,

$-e^{-y} = -\frac{5}{2}x^{2} + C$

$e^{-y} = \frac{5}{2}x^{2} + C$

Then,

$ln(e^{-y}) = ln(\frac{5}{2}x^{2} + C)$

Then,

$-y = ln(\frac{5}{2}x^{2} + C)$

Hence,

$y = - ln(\frac{5}{2}x^{2} + C)$

-Find the y-intercept of the line with the equation 2x+y=5.

AlekseyPX

Answer:

E. 5

Step-by-step explanation:

Let's rewrite the equation in the form of y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).

2x + y = 5

y = -2x+5

M, the slope, is -2

<u>5, b, is the y-intercept</u>

See attached graph.
