Which of the following is equivalent to the expression below for x≠6?
nata0808 [166]

Answer:

The fourth answer choice is the correct one:  2(x - 3)

Step-by-step explanation:

2x²-18x+36/x-6 should be factored, as follows:

2(x²-9x+18) / (x-6) = 2(x - 3) (x - 6) / (x - 6)

Substituting x = 6 would result in division by zero and is thus not allowed.

Remembering this, we can reduce 2(x - 3) (x - 6) / (x - 6) to 2(x - 3) for x≠6.

Given the statement, LEI=BNZ and the diagrams shown, determine the value of x.
WARRIOR [948]

Answer:

x = 20

Step-by-step explanation:

Given the triangles are congruent then corresponding angles are congruent, so

∠ N = ∠ E

To calculate ∠ E subtract the sum of the 2 given angles from 180

∠ E = 180 - (x - 5 + 4x - 10)

     = 180 - (5x - 15)

Equate ∠ N and ∠ E

5x - 5 = 180 - 5x + 15 ( add 5x to both sides )

10x - 5 = 195 ( add 5 to both sides )

10x = 200 ( divide both sides by 10 )

x = 20

Find the average rate of change of f(x)=2x^2-7x from x=2 to x=5
m_a_m_a [10]

Answer:

7

Step-by-step explanation:

The average rate of change of f(x) in the close interval [ a, b ] is

\frac{f(b)-f(a)}{b-a}

Here [ a, b ] = [2, 5 ]

f(b) = f(5) = 2(5)² - 7(5) = 50 - 35 = 15

f(a) = f(2) = 2(2)² - 7(2) = 8 - 14 = - 6, thus

average rate of change = \frac{15-(-6)}{5-2} = \frac{21}{3} = 7
