We will see that the number of students that play both sports is given by the inequality:

5 ≤ x ≤ 9

We do know that in the class, there are 15 students.

Such that:

If you add these numbers, you get:

9 + 11 = 20

This gives more than the number of students that we have, to get the minimum number of students that play both sports we subtract the number of students:

20 - 15  = 5

5 students play both sports, but this is the minimum number.

There is also the case where out of the 11 students that play soccer, there are 9 that play basketball (so 9 students play both sports) and 4 students don't play any sport.

So the number of students that play both sports is given by the inequality:

5 ≤ x ≤ 9

Bennet can lift 600 pounds without resting.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let n represent the total number of ounces he can lift without resting, hence:

n = 200 pounds * 3

n = 600 pounds

do long or synthetic division.  the quotient = 3x + 22 with remainder 81

with long division first divide x into 3x^2 to get 3x.  Then

3x times (x-4) = 3x^2-12x

subtract that from 3x^2+kx to get   (k-12)x bring down the -7 to get

(k-12)x -7

you want a remainder of 81, so you want -4 times a constant to = -88  (-7-(-88)=81

4 x 22 =88.  22 is the constant

22=12+k

k=10

Factors of a polynomial together constitute the polynomial by multiplication. The factored form of [tex]12c^9 + 28c^7[/tex] is [tex]= 4c^7(3c^2 + 7)[/tex]

Suppose a, b and c are three numbers. Then we have:

[tex]a(b + c) = a\times b + a\times c[/tex]

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

Remember that many times, when using letters or symbols, we hide multiplication and write two things which are multiplied, close to each other. As in [tex]2 \times x = 2x[/tex]

The given polynomial is [tex]12c^9 + 28c^7[/tex]

To factor it, we can use the fact that 12 and 28 are both having 4 as common factor since:

[tex]12 = 4 \times 3 \\28 = 4 \times 7[/tex]

Thus, the given polynomial is factored as:

[tex]12c^9 + 28c^7 = 4 \times 3 \times c^7 \times c^2 + 4 \times 7 \times c^7 = 4c^7(3c^2 + 7)[/tex]

Thus,

The factored form of [tex]12c^9 + 28c^7[/tex] is [tex]= 4c^7(3c^2 + 7)[/tex]

Answer: The percentage of the tub after 6 minutes is 30 %

Step-by-step explanation: The  calculation can be done as follows

1 minutes= 4 gallons

6 minutes= 4×6

= 24 minutes

If the bathtub can hold 80 gallons of water then the percentage of the tub after 6 minutes can be calculated as follows

= 24/80

= 0.3 × 100

= 30 %

Hence the percentage of the tub will be filled after 6 minutes is 30 %

Answer:

A

Step-by-step explanation:

If you simplify 40/100, you should get 4/10, which is still the same amount that Mark has.

You simplify by finding the greatest common factor between 40 and 100. In this case, it is 10. So you divide 40 by 10 and 100 by 10 to simplify.

Answer: Hopefully the math terms won't confuse anyone.

So in the series, a_3 = -1 and a_7 = -13. Since it's an arithmetic sequence, all the terms in the series can be represented as:

a_n = a_0 + n * k

where n is the nth number. K is a constant you add to reach the next term, and a_0 is the starting constant.

a_7 = a_0 + 7 * k

a_3 = a_0 + 3 * k

solving this system gives you that

k = - 3 and a_0 = 8

Hence:

a_22 = 8 + 22 * -3 = -58
