Mathematics
1 answer:
Sonja [21]3 years ago
5 0

Answer:

(7,9)

Step-by-step explanation:

7x - 8y = -23

7x - 7y = -14

Solve the equation for 7x

7x - 8y = -23

7x = -14 + 7y

Substitute the given value of 7x into the equation 7x - 8y = -23

-14 + 7y - 8y = -23

solve the equation for y

y = 9

substitute the given value of y into the equation 7x = -14 + 7y

7x = -14 + 7(9)

solve the equation for x

x = 7

<u>(7,9)</u>

Write the product of 0.4×0.4×0.4 in exponential form
bearhunter [10]
<span>0.4×0.4×0.4 is equal to 0.4 to the third power, or 0.4</span>³
To convert to exponential form, count how many times the number is multiplied by itself and make that number the exponent. In this case, the 0.4 is multiplied by itself 3 times, so our exponent is 3. 

Answer is 0.4³

There are 8 performers who will present their comedy acts this weekend at a comedy club. One of the performers insists on being
Korvikt [17]
This is a permutations problem. There are only 7 comics you can move into different time slots, the 8th one being fixed in that last position. So you can look at it this way:
For the 1st position, you can choose from all 7 people. Once you've picked that one, you have 6 people to choose from for the 2nd position, and similarly for the remaining ones . This gives you 7x6x5x4x3x2x1 = 5040 ways to arrange them. And the last comic stays in the same position all the time so does not change this number. Make sense? If you need to demonstrate it to yourself, use a smaller number of comics, like 3 or 4, and write out the combinations to see that it works.
