Hi there!

[tex]3|x+y|^2-(xy)^2[/tex]

Replace x with 3 and y with -5

[tex]= 3|3+(-5)|^2-[(3)(-5)]^2\\= 3|3-5|^2-(-15)^2\\= 3(2)^2-225\\= 3(4)-225\\= 12-225\\= -213[/tex]

[tex]6x - 8 = 2x + 4 \\ 6x - 2x = 4 + 8 \\ 4x = 12 \\ x = 3[/tex]

Answer:

C.) x = 3

Step-by-step explanation:

The diagonals of a rectangle are equal, and QM and PM are both half of the two diagonals. You can now say that 2 * (6x - 8) = 2 * (2x + 4), meaning that 12x - 16 = 4x + 8, where you can add 16 on both sides, then subtract by 4x on both sides to get that 8x = 24. Now divide by 8 on both sides to get that x = 3.

1. When adding two integers, what will the sign of the sum be if: c. one integer is positive and one integer is negative?

Answers

Answer:

Step-by-step explanation:

The largest absolute value gets the sign.

To use an example

4 - 8

Think money for a moment. You have 4 dollars in your pocket. You owe your mother 8 dollars. Where are you?

You should think you are 4 dollars in debt. That being the case, the sign of the answer is minus.

4 - 8 = -4  Eight is the largest number if its absolute value is taken. Absolute value means you turn it positive and subtract.

Suppose the question is

-9 + 5   Again money. You have 5 dollars in your pocket, but this time you owe mom 9 dollars

She wants her -4 dollars right now.

ROCKET SLED On a track at an Air Force base in New Mexico, a rocket sled
travels 3 miles in 6 seconds. What is the average speed in miles per hour?

Answers

Answer:

Answer: Rocket distance (rocket sled) =3 mil Time Taken=6seconds

Average Speed=Total Distance ÷ Time Taken. Average speed= 3÷ 6=1/2. So therefore average speed in miles per seconds= Average in miles/seconds

Average speed in miles per seconds=1/2

Average in miles/hour = Average speed in miles per seconds/hour.

Average in miles/hour=1/2÷60=30

Therefore Average speed in miles per hour =30 miles per hour

Berny bought a soft drink for 2 dollars
and 6 candy bars. He spent a total of
20 dollars. How much did each candy bar cost
bar cost?

Answers

Answer:

3

Step-by-step explanation:

Given:

Berny spent 20 dollars total

He spent 2 dollars on a soft drink

He bought 6 candy bars

Solution:

Amount spent on candy bars = total amount spent - amount spent on soft drink.

Amount spent on candy bars = 20 - 2 = 18

Cost of each candy bar = total amount spent on candy bars / # of candy bars bought

Cost of each candy bar = 18/6 = 3

Answer: Each candy bar costs $3

Step-by-step explanation:

Set variables

Soft drink = $2

Candy bars = $6x

Let x be the cost for each candy bar.

Total cost = $20

Set equation

2 + 6x = 20

Subtract 2 on both sides

2 + 6x - 2 = 20 - 2

6x = 18

Divide 6 on both sides

6x / 6 = 18 / 6

x = 3

Answers

Answer:

B) [tex]x\geq0[/tex]

Step-by-step explanation:

The domain of the square root function is all real non-negative numbers. In a numerical format that is as follows:

[tex]D(\sqrt{x})={[0,\infty )}[/tex]

This is more commonly denoted as:

[tex]x\geq0[/tex]

In the case of the given function:

[tex]g(x)=\sqrt{8x}[/tex]

The domain is still ([tex]x\geq0[/tex]) as multiplying a value by (8) does not alter this. A negative number times (8) is still negative and thus cannot be a part of the square root domain. Similarly, a positive number times (8) is still positive and remains a part of the square root domain. Moreover, (0) times (8) is still (0).

Jaulas father throws Kayla a graduation party that costs $773. He pays the DJ $250, $75 for the cake, and $4 per party guest for food. How many guests were at the party?

Answers

Answer:

112 guests

Step-by-step explanation:

I. If her total cost is 773$

When Total = DJ + Cake + Guest

            773 = 250 + 75 + 4(x)

            773 = 325 + 4(x)

            773 - 325 = 4(x)

            448 = 4x

               x = 448/4

               x = 112

That makes guests are 112
