Solve the equation for all values of x by completing the square.
x^2 + 6x – 27 = 0

Answers

Answer 1

Answer:

Solution

=3

=−9

x=3

x=−9

x=3x=−9

Step-by-step explanation:

Boom

Answer 2

Answer:

x=-9 and 3

Step-by-step explanation:

FOIL method

x^2+6x-27=0

Find the common numbers that multiply to 27 that will also equal 6.

(27x6) or (9x3)

the 6 is positive while 27 is negative so you need to use a + and - in the parenthesis.

then FOIL them

(x+9)(x-3)

FIRST:  x*x=x^2

OUTSIDE: x*-3=-3x

INNER: 9*x=9x

LAST: +9*-3=-27

x^2(-3x9x)-27

x^2+6x-27

now that the equation matches you solve for x.

(x+9)=0  x=-9

(x-3)=0   x=3

A restaurant sells burritos for $8.00 each. The cost of the meat is $1.50 and the cost of the other ingredients is $1.00 for each burrito. Money made from selling burritos is positive. The cost of making burritos is negative. Profit is the money left after paying the costs.

How much profit would the restaurant make by selling 100 burritos?


What is the cost of making one burrito? (Remember that costs are negative.) Explain how you found your answer.




Write your answer in the space below.

Answers

Answer:

Profit for 100 burritos: $550

Cost to make one burrito: $2.50

Step-by-step explanation:

If a restaurant sells burritos for $8, that's a positive 8 dollars they earned. Then, we need to find what the cost was to make the burrito. If the meat is 1.50 and the cost for all the other ingredients is 1 dollar, then they lose 2.50 for every 8 dollars they make (for each burrito). So, to find the profit in one burrito, we would add -2.5+8, giving us an answer of 5.5. So, they earn 5 dollars and 50 cents each burrito and lose $2.50.

Now, we need to find the profit of 100 burritos

If one burrito is $5.50 in profit, then we take that amount and multiply it by 100. This is to make the illitsratution of selling 100 burritos. So, 5.50*100 would be 550! They would make $550 for 100 burritos, and lose 250 dollars on all of the burrito ingredients.  

the answer is 550 and 2.50

Consider the points (-5,2) and (3,-9)
What's the horizontal distance between the two points?

Answers

Answer:

The distance between the 2 points is about 13.6

Step-by-step explanation:

Picture the 2 points on a graph, and then look at the distance between them as the hypotenuse of a right triangle. You can easily find the length of the legs of that triangle, and with those legs, you can use the pythagorean theorem to calculate the length between the points.

The length of one leg is the distance between the 2 x-coordinates, between -5 and 3, so that's 8.

[tex]3--5=3+5=8[/tex]

The length of the other leg is the distance between the y, between 2 and -9.

[tex]-9-2=-11[/tex]

That's just a distance of 11, as there's no such thing as negative distance.

Now we have the legs, so we can find the hypotenuse:

[tex]a^2+b^2=c^2\\8^2+11^2=c^2\\64+121=c^2\\c^2=185\\c\approx13.6[/tex]

Graph the solution to this inequality on the number line. −1/3x + 1/2 ≥ −3/4

Answers

Answer:

4.5 (4.5 units to the left of 0) Make sure to draw a solid dot over 4.5 and an arrow pointing in the right direction.

>= is the greater than or equal to symbol

Step-by-step explanation

1. Combine like terms- In this problem, the like terms are 1/2 and -3/4, so to move 1/2 over to the other side of the equation, we have to divide each side by 2/1, which is the same as multiplying each side by 2: -1/3x + 1/2 * 2 >= -3/4 * 2.

2. Separate the fraction from x- Now, we simply divide each side by -3/1, which is the same as multiplying each side as -3: -1/3x * -3 >= -3/2 * -3

3. Graph on the number line- We've found that x = 4.5. To check, substitute in 4.5 for the value of x: -1/3(4.5) + 1/2 >= -3/4. -1 >= -3/4 is a true inequality. To graph it on the number line, draw a solid dot over 4.5 and an arrow in the direction of the righthand side.

8. Multiply the following:

c. (3s^4)(-6s^5)

Answers

The result of the multiplication is (-18s^9).

To multiply the two expressions (3s^4)(-6s^5), you can use the distributive property, which states that you can multiply a term by each of the terms inside a set of parentheses.

Using the distributive property, you can rewrite the expression as:

(3s^4)(-6s^5) = 3s^4 * -6s^5

Then, you can simplify the expression by combining like terms:

3s^4 * -6s^5 = (-18s^9)

So the result of the multiplication is (-18s^9).

A cookie recipe calls for ¾ cup of sugar. You have the

Suppose your ¼ cup is missing. How would you measure ¾ cups of sugar using at least two of the other measuring cups? Show your work.

Answers

Answer:

1/2 cup and 2 1/8 of a cup

Step-by-step explanation:

1/8 +1/8=1/4

1/2 is equaled to 2/4

so 2/4+1/4=3/4

You need 3/4 cup of sugar and your 1/4 is missing
First use the 1/2 cup which is equal to 2/4
Now a tablespoon is 1/16 of a cup, so use 4 table spoons, which is 1/4 of a cup
You finally have 3/4 cups of sugar because you have 1/2 cups of sugar and 4/6 cup of sugar
