Examine the system of equations, Y = -1/4x -2 , x=4 What is the solution

Nina [5.8K]

Answer:

Y = -1/14

Y = -0.0714

Step-by-step explanation:

Y = -1/4x -2 , x=4

Solution:

Y = -1/4x -2 .........equation(a)

put x = 4 in equation(a)

Y = -1/4(4) -2

Y = -1/16 -2

Y = -1/14

Y = -0.0714

Match the following equation to the correct situation

zepelin [54]

The correct answer is C.

14%p can be written as 0.14p, since 14%=14/100=0.14.

Adding this to p means paying 100% of p plus an additional 14%. This would be equivalent to paying sales tax on a purchase.

The total cost (in dollars) for a company to manufacture and sell x items per week is C=40x+180, whereas the revenue brought in

crimeas [40]

Answer:

The company needs to sell either 30 or 40 items.

Step-by-step explanation:

We are given that the cost for selling x items given by the function:

$C(x)=40x+180$

And the revenue for selling x items is given by:

$R(x)=68x-0.4x^2$

The profit function is the cost function subtracted from the revenue function:

$P(x)=R(x)-C(x)$

Substitute and simplify:

$\displaystyle \begin{aligned} P(x)&=(68x-0.4x^2)-(40x+180)\\&=68x-0.4x^2-40x-180\\&=-0.4x^2+28x-180\end{aligned}$

To find how many items must be sold in order to obtain a weekly profit of $300, we can let P equal 300 and solve for x. So:

$300=-0.4x^2+28x-180$

Solve for x. Subtract 300 from both sides:

$-0.4x^2+28x-480=0$

We can divide both sides by -0.4:

$x^2-70x+1200=0$

Factor:

$(x-40)(x-30)=0$

Zero Product Property:

$x-40=0\text{ or } x-30=0$

Solve for each case:

$x=40\text{ or } x=30$

So, in order to obtain a weekly profit of $300, the company need to sell either 30 or 40 items.

If (x – 4) + 6 = 2 - (4 - 2x), then x = A. -4 B. -2 C. 2 D. 4

blondinia [14]

Answer:

x=4

Step-by-step explanation:

Remove the parentheses and turn the 4-2x and make it into 4+2x candle the equal term -4 and should be left with x+6=2+2x then move the variable to the left and change the sign so it would be x-2x=2-6 and collect like terms so it would be -x=2-6 and then calculate that and get -x= -4
