If two lines don’t intersect, then is it parrell (( true or false ))

1 answer:

7 0

The definition of parallel lines states that they don't intersect, so that would always be true. (In Euclidean geometry, anyway.)

f(x) + g(x) = 3x + 2 + 2x + 5 = 5x + 7

f(x) - g(x) = 3x + 2 - 2x - 5 = x - 3

(2)

f(x) + g(x) = 4x - 1 + 3x - 4 = 7x - 5

f(x) - g(x) = 4x - 1 - 3x + 4 = x + 3

(3)

f(x) + g(x) = - 5x + 3 + 2x - 4 = - 3x - 1

f(x) - g(x) = - 5x + 3 - 2x + 4 = - 7x + 7

(4)

f(x) + g(x) = 3x - 4 - 2x + 3 = x - 1

f(x) - g(x) = 3x - 4 + 2x - 3 = 5x - 7

(5)

f(x) × g(x) = - 2(- x + 7 ) = 2x - 14

(6)

f(x) × g(x) = - 5(2x - 7) = - 10x + 35

The table of values represents a function f(x).

NeX [460]

Answer:

The average rate of change over the interval [9,10] is greater than that over the interval [5,8] by 6490.

Step-by-step explanation:

The value of f(x) = 4052 for x = 9 and f(x) = 11014 for x = 10.

Therefore, the average rate of change of f(x) with respect to x over the interval [9,10] is given by

= $\frac{\textrm {Total change in value of f(x)}}{\textrm {Total change in value of x}}$

= $\frac{11014 - 4052}{10 - 9} = 6962$

Now, the value of f(x) = 75 for x = 5 and f(x) = 1491 for x = 8.

Therefore, the average rate of change of f(x) with respect to x over the interval [5,8] is given by

= $\frac{\textrm {Total change in value of f(x)}}{\textrm {Total change in value of x}}$

= $\frac{1491 - 75}{8 - 5} = 472$

Therefore, the average rate of change over the interval [9,10] is greater than that over the interval [5,8] by (6962 - 472) = 6490. (Answer)
