Answer:

Step-by-step explanation:

A system of inequalities of two variables is a set of inequalities of two variables that act at the same time, that is, the solution points must meet all the inequalities of the system.

Then you must first define what the system variables will be. You know that Rasheed is buying wings and quesadillas for a party. Then your variables will be:

  • w: number of package of wings bought by Rasheed.
  • q: quantity of package of quesadillas bought by Rasheed.

You know too that a package of wings costs $8 and a package of quesadillas costs $10. Then $ 8*w and $ 10*q will be the price paid for the amount of packages bought from wings and quesadillas by Rasheed respectively. If he must spend no more than $160 between winds and quesadilla, so:

<u><em>8*w + 10*q ≤ 160</em></u>

On the other hand, Rasheed's freezer will hold a maximum of 20 packages of wings and quesadillas.  So the quantity of packages of wings and quesadillas bought by Rasheed should not exceed the quantity of 20.

Therefore, <u><em>w + q ≤ 20</em></u>

Finally, the system of linear inequalities is:

<em>\left \{ {{8*w+10*q\leq 160} \atop {w+q\leq 20}} \right.</em>

To find the solution of the system, look for the solutions of each of the inequalities of the system and look at the regions where they will coincide.

That is, a possible method of finding common regions among all inequalities is to first find each region of each inequality. Then all the solutions are drawn on the same plane. The regions thus overlap, being able to easily see which regions will be a system solution.

In the attached image you can see the graph of both inequations. One region is marked green, belonging to the inequality w + q ≤ 20, while the other region is marked violet, belonging to the inequality 8*w + 10*q ≤ 160.

The areas where it is shaded by both colors, this is the intersection of the regions solutions, will be the solutions of the inequality system.

Arlene buys a phone case and charging cord for 15% off. The original cost of the phone case is $18. Her total discount is $4.20.
mel-nik [20]

Answer: $10

Step-by-step explanation:

Assume the price of the phone case is x.

Assume the price of the charging cord is y.

Discounted price for phone case :  15% * x

= 0.15x

Discounted price for charging cord = 0.15y

Expression is therefore:

0.15x + 0.15y = 4.20

0.15 * 18 + 0.15y = 4.20

2.7 + 0.15y = 4.20

0.15y = 4.2 - 2.7

y = 1.5/0.15

y = $10

Please help with the questions in the image
iren2701 [21]

Step-by-step explanation:

This seems to be calculus 1.

<u>Question a</u>

We have -2x^3 + 5x^2 + 9

m = slope = derivative

Find the derivative / slope of -2x^3 + 5x^2 + 9

We do this by differentiating the polynomials. There are a few methods to do this but I am going to use the power rule, which we multiply the constant by the exponent on the variable and subtract one from the exponent.

\frac{d}{dx}(-2x^3 + 5x^2 + 9)

-6x^2 + 10x

m = -6x^2 + 10x when x = a

<em>Now that we have this information, we can answer question b</em>

<u>Question b</u>

<u>The tangent line for Point (1, 12)</u>

First find the slope by using our derivative.

m = -6x^2 + 10x

m = -6(1)^2 + 10(1)

m = -6 + 10x

m = 4

Now that we have our slope, use point slope form to find our tangent line

y - 12 = 4(x - 1)

y(x) = 4x + 8


<u>Now lets do the same for the Point (2, 13)</u>

Find the slope at the point.

m = -6x^2 + 10x

m = -6(2)^2 + 10(2)

m = -24 + 10

m = -4

Now find the tangent line using point slope form of a line.

y(x) - 13 = -4(x - 2)

y(x) = -4x + 21


Now graph the lines, which I have done and you can see by viewing the image I have attached.

Easy variable question pls help
svet-max [94.6K]

Answer:

z = -4 1/2

Step-by-step explanation:

1. First change the mixed fractions to improper fractions so it's easier

\frac{16}{5\\}/(z-\frac{1}{2}) = \frac{8}{3}/(z+\frac{1}{3})

2. Simplify

\frac{32}{5(2z-1)} = \frac{8}{3z+1}

3. Cross multiply

32(3z+1) = 5(2z-1) * 8

4. Simplify again (distributive property)

32(3z+1) = 40(2z-1)

5. Distributive property

32(3z+1) -> 96z+32  

40(2z-1) -> 80z-40

96z+32=80z-40

6. Subtract 32 from both sides

96z+32-32 = 80z-40-32

7. Simplify

96z = 80z-72

8. Subtract 80 from both sides

96z-80z=80z-72-80z

9. Simplify

16z=-72

10. Divide both sides by 16

\frac{16z}{16}=\frac{-72}{16}

11. Simplify

z=-\frac{9}{2} -> also = -4\frac{1}{2}

Sorry if it was too long but hope this helps! :)

And also try using symbolab cuz it gives step by step explanations it's really good!
