Directions; Write a system of equations for each of the descriptions below, and then solve the systems. Hint: you can graph the equations to find the solutions.

There are two numbers. The difference between them equals six, and one of the numbers is three times the other number. There are two pairs of numbers that satisfy these descriptions, What are they?

Answer:

1) 3^2 or 9

2)5^18

Step-by-step explanation:

Ok but you have to hit that crown :D

Simplify: 3^8x3^4 = 3^12

3^2x3^8=3^10

3^12/3^10 = 3^2 or 9

5^3^6=5^18

Hope this helps :D

Answer:

BC = 8

Step-by-step explanation:

AB + BC = AC

4x + 8 + 3x - 4 = 32

7x + 4 = 32

7x = 32 - 4

7x = 28

x = 28/7

x = 4

BC = 3x - 4 = 3*4 - 4 = 12 - 4 = 8

Answer:

B) 8

Step-by-step explanation:

The Segment Addition Postulate basically states that the sum of the segments of a line will equal the length of the entire line.

Thus, AB+BC=AC, and we can substitute:

AB+BC=AC

(4x+8)+(3x-4)=32

4x+8+3x-4=32

7x+4=32

7x=28

x=4

Now that we have x, we can plug it in for segment BC:

BC=3x-4

3(4)-4

12-4

8

Therefore, choice B is correct

Answer:it would be 1:2

Answer:

1 : 2

Step-by-step explanation:

2 : 4

A ratio is another way of expressing a fraction. Hence, if one divides both sides by the same number, it will be the equivalent of one reducing a fraction, and it will still be equivalent to the original value. Hence, to reduce this ratio; divide both sides by 2

1 : 2

The given decimal number 9.78778777... is non-terminating and non-recurring it is an irrational number.

The given decimal number is 9.78778777....

We need to check whether the given decimal number is a rational or irrational number.

Rational numbers: Rational numbers are in the form of p/q, where p and q can be any integer and q ≠ 0. This means that rational numbers include natural numbers, whole numbers, integers, fractions of integers, and decimals (terminating decimals and recurring decimals).

Irrational numbers: Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, p/q where p and q are integers. The denominator q is not equal to zero (q ≠ 0). Also, the decimal expansion of an irrational number is neither terminating nor repeating.

So, from the definition of rational and irrational numbers, we can say the given decimal number 9.78778777... is irrational.

Since the given decimal number 9.78778777... is non-terminating and non-recurring it is an irrational number.

Answer:

Not entirely sure about what the question is asking, but explanation of what I think it is asking.

Step-by-step explanation:

There are three basic rules of addition.

Positive + Positive = Positive Ex: 1+1=2

Negative + Negative = Negative Ex: -2+-2=-4

Negative + Positive = Positive or Negative depending on the value.

Ex= 1+(-2)=(-1)

Ex=2+(-1)=1

So subtraction problems can be turned into addition problems.

For example:

4-2 is the same as 4+(-2).

Or -5-7 is the same as -5+(-7).

Hope this makes sense.

Answer:  

X + Y = 5.678

X - Y = 9.876

The two numbers: X = 7.777   Y = -2.099

Step-by-step explanation: solve by elimination

X + Y = 5.678

X - Y = 9.876 . Add the two equations so the y cancels. Solve for x

2x = 15.554 .  Divide both sides by 2

X = 7.777    Substitute in the original equations to find Y

7.777 + y = 5.678 . Subtract 7.777 from both sides

Y = - 2.099

check in the second equation:

7.777 -(-2.099) = 9.876

7.777 + 2.099 = 9.876 True

The two numbers is X = 7.777 and Y = -2.099.

And, the two equation is X + Y = 5.678  and X - Y = 9.876.

Given that,

Based on the above information, the calculation is as follows:

X + Y = 5.678

X - Y = 9.876

2x = 15.554  

X = 7.777    

Now  

7.777 + Y = 5.678  

Y = - 2.099

Therefore, the above should be the answers.

Step-by-step explanation:

Given the inequality, y > -½, the graph that represents this would have a directed line starting from -½ and pointing to your right. It would also have an unshaded circle, or empty circle, signifying that -½ is not included among the set of possible values of y.

Thus, the right graph would be graph A.

Take 25% of 60 and that is 15. Please give me brainliest

Answer:

$45.00

Step-by-step explanation:

To find percentage, most start out by dividing the percent by 100:

25 ÷ 100 = 0.25

Then, to find the percentage of 60, we multiply them.

$60 x 0.25 = $15

15 is 25% of 60. However, we're asking the sale price of the video game, not the amount it was reduced. To find this out we subtract the reduced amount from the original number:

$60 - $15 = $45
