Using f(x) = 3x - 3 and g(x) = 2x, what is f(4) - g(2) ?

Zielflug [23.3K]

Answer:

Step-by-step explanation:

evaluate f(4) by substituting x = 4 into f(x) and g(2) by substituting x = 2 into g(x)

f(4) = (3 × 4) - 3 = 12 - 3 = 9

g(2) = (2 × 2 ) = 4

f(4) - g(2) = 9 - 4 = 5

During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by

Alja [10]

Answer:

The numbers of measure of music played are 1 and 7

Step-by-step explanation:

Given

$s = 10|x - 4| + 50$

Required

Solve for x when s = 80

Substitute 80 for x

$80 = 10|x - 4| + 50$

Subtract 50 from both sides

$80 - 50= 10|x - 4| + 50 - 50$

$30= 10|x - 4|$

Divide through by 10

$\frac{30}{10}= \frac{10|x - 4| }{10}$

$3= |x - 4|$

Reorder

$|x - 4| = 3$

This can be split into

$x - 4 = 3$ or $x - 4 = -3$

Solve for x

$x = 4 + 3$ or $x = 4 - 3$

$x = 7$ or $x = 1$

Hence:

<em>The numbers of measure of music played are 1 and 7</em>
