The correct answer is a. 

You can find this by using each of the ordered pairs in the equation and seeing if the statements are true. The work for the a ordered pairs is below. 

(-2, -14)
y = 7x
-14 = 7(-2)
-14 = -14

(3, 21)
y = 7x
21 = 7(3)
21 = 21

(-4, -28)
y = 7x
-28 = 7(-4)
-28 = -28

A number is greater than 8. The same number is less than 10. The inequalities x greater-than 8 and x less-than 10 represent the
jok3333 [9.3K]

Answer:

There are a few solutions because there are some fractions and decimals between 8 and 10

Step-by-step explanation:

Let the unknown number be 'x'

If the number is greater than 8 and the same number is less than 10, this can be expressed as;

x>8 and x < 10

Note that if x>8, then 8<x

The resulting inequalities are now;

8<x and x<10

Combining both inequalities we have: 8<x<10

Since the inequality didn't tell us that the variable 'x' is equal to 8 and 10, this means that our solution falls between 8 and 10 and the value of integer that falls within this range is 9. Other values that falls within this range are decimals and fractions.

Therefore it can be concluded that there are a few solutions because there are some fractions and decimals between 8 and 10

pochemuha

Answer:

336 ways

Step-by-step explanation:

The digits are 1, 2, 2, 4, 5, 5, 6, and 2 that is total eight digits.

The number 654-5222 contains 7 digits.

So, we have find The number of permutations for choosing 7 digits from 8 digits given above.

This can be done in following ways

\frac{8!}{3!\times2!} = \frac{40320}{6\times2}

= 336 ways
