SIZIF [17.4K]

Answer:

Option A is the correct choice.

Step-by-step explanation:

Let d be the number of boxes of duck calls and t be the number of boxes of turkey calls.

We have been given that a company sells boxes of duck calls for $35 and boxes of turkey calls (t) for $45, so the revenue earned from selling d boxes of duck and t boxes of turkey call will be 35d and 45t respectively.

Further, the company plan to make $300. We can represent this information as:

$35d+45t=300...(1)$

We are also told that they make batches of duck calls that fill 6 boxes and batches of turkey calls that fill 8 boxes. the company only has 42 boxes. We can represent this information as:

$6d+8t=42...(2)$

$6d=42-8t...(2)$

Therefore, our desired system of equation will be:

$35d+45t=300...(1)$

$6d=42-8t...(2)$

If y= -3x7+2x3+ x, the derivative of y with respect to x is

larisa [96]

Answer:

$\frac{dy}{dx}$ = - 21 $x^{6}$ + 6x² + 1

Step-by-step explanation:

Differentiate each term using the power rule

$\frac{d}{dx}$ (a $x^{n}$ ) = na $x^{n-1}$

Given

y = - 3 $x^{7}$ + 2x³ + x , then

$\frac{dy}{dx}$ = (7 × - 3 ) $x^{6}$ + (3 × 2)x² + (1 × 1 ) $x^{0}$

= - 21 $x^{6}$ + 6x² + 1

Y + 3y + 5y = -18 what is the value of y

ANEK [815]

Answer:

y = -2

Step-by-step explanation:

Step 1: Combine like terms.

$(y+3y+5y)=-18$
$9y=-18$

Step 2: Divide both sides by 9.

$9y/9=-18/9$
$y=-2$

Step 3: Check if solution is correct.

$-2+3(-2)+5(-2)=-18$
$-2-6-10=-18$
$-18=-18$

Therefore, y = -2.
