A wholesale distributor of packaged nuts sells two different mixes of peanuts and cashews, mix A and mix B. Each package of mix

Tom [10]

Answer:

The answer is below

Step-by-step explanation:

Let x represent the number of packages of mix A nuts and let y represent the number of packages of mix B nuts

Since 8 ounces (oz.) of peanuts is used to produce a package of mix A and 6 ounces (oz.) of peanuts is used to produce a package of mix B. Also, No more than 120 oz. of peanuts can be used each day. This can be represented by the inequality:

8x + 6y ≤ 120 (1)

4 ounces (oz.) of cashew is used to produce a package of mix A and 6 ounces (oz.) of cashew is used to produce a package of mix B. Also, No more than 96 oz. of peanuts can be used each day. This can be represented by the inequality:

4x + 6y ≤ 96 (2)

The inequality from equation 1 and equation 2 is graphed using geogebra online graphing.

If x, y ≥ 0, the solution to the problem is:

(0, 0), (0, 16), (15,0), (6, 12)

Solve the quadratic equation by taking the square root of (x+5)^2=16

Liula [17]

Hi okay i’m gonna write the explanation i hope you give me a brilliant if you think I’m deserving it thank you

(x-5)2=16

The first step you can take to solve this quadratic is to take the square root of both sides of the equation.

√[(x-5)2]=√(16)

When you take the square root of a term that is square it equals what is inside the parentheses.

So on the left side, you have x-5

On the right side, you are what we call "forcing" the square root. When this happens, you need to put ±. Why? Good question. When you square a negative number it positive; when you square a positive number it is also positive.

The √16 = ±4

So now we have;
x-5=±4

What do you do with that?
You make two separate equations.

x-5=4 and x-5=-4
x=9 x=1

Let's check our answers

x=9

(x-5)2=16
(9-5)2=16
42=16
16=16 it checks

x=1

(x-5)2=16
(1-5)2=16
(-4)2=16
16=16 it also checks

ANSWER: x=9 and x=1
