Use the number set to answer the question.

Mathematics
1 answer:
Fantom [35]4 years ago
8 0

Answer:

7

Step-by-step explanation:

The median is the middle value of the data set arranged in ascending order.

If there is no exact value then it is the average of the values either side of the middle.

Arrange the data in ascending order

1, 4, 6, 8, 8, 9

The middle is between 6 and 8, thus

median = \frac{6+8}{2} = \frac{14}{2} = 7

Find the values of x for which the denominator is equal to zero for y=3x+6/x^2-5x+6
lilavasa [31]

Answer:

x = 2

and

x = 3

Step-by-step explanation:

The function given is:

y=\frac{3x+6}{x^2-5x+6}

In this fraction, the bottom part is the denominator. We need to set it equal to 0 and solve for 2 values of x.

x^2-5x+6=0\\x^2-3x-2x+6=0\\x(x-3)-2(x-3)=0\\(x-2)(x-3)=0\\x=2,3

This is middle term factorization process. Hence the 2 solutions (roots) of the denominator is:

x = 2, 3

Simplify the expression. 3t(t - 5) + 6t to the 2nd power
Nadusha1986 [10]
<span>: 2s + 3t = 28, 2s = 28 - 3t s = 14 - 3t/2 Substitute s into second equation 5s + 6t = 61, 5(14 - 3t/2) + 6t = 61, 70 - 15t/2 + 6t = 61, 70 - 3t/2 = 61, 3t/2 = 9, t = 6. We can then substitute t back into first equation: 2s + 3t = 28, 2s + 3 * 6 = 28, 2s = 10, s = 5. So the final answer is: s = 5 t = 6</span>

Which of the algebraic expressions are not linear expressions? Select all that apply. a. 3x - 2 b. -9y c. -7x^2^ + 4x d. -1/2x^2
Sedaia [141]

Answer:

c, d and e

Step-by-step explanation:

A linear expression is an expression in which sum of exponents of variables is at most 1 in each of its terms.

Option a: 3x - 2

Here, the exponent of the variable is 1.

So, it is a linear expression.

Option b: -9y

Here, the exponent of the variable is 1.

So, it is a linear expression.

Option c: -7x^2 + 4x

Here, the highest exponent of the variable is 2.

So, it is NOT a linear expression.

Option d: -\frac{1}{2} x^2

Here, the exponent of the variable is 2.

So, it is NOT a linear expression.

Option e: 8xy

Here, sum of exponents of variables is 2.

So, it is NOT a linear expression.

Hence, c, d and e are NOT algebraic expressions.
