Find the percent of change from 18 to 12.

1 answer:

8 0

Answer:

18 is the old value and 12 is the new value. In this case we have a negative change (decrease) of -33.33333333 percent because the new value is smaller than the old value.

What is the result when 4x3 + 19x2 + 29x + 14 is divided by 4x + 7?

Sergio039 [100]

Step-by-step explanation:

4x³ + 19x² + 29x + 14

= (4x³ + 7x²) + (12x² + 21x) + (8x + 14)

= x²(4x + 7) + 3x(4x + 7) + 2(4x + 7).

= (x² + 3x + 2)(4x + 7).

Hence 4x³ + 19x² + 29x + 14 divided by 4x + 7 is x² + 3x + 2 or (x + 1)(x + 2).

Which function represents a reflection of f(x) = Three-sevenths(2)x over the x-axis?

NemiM [27]

<u>Given:</u>

The given function is $f(x)=\frac{3}{7}(2)^{x}$

We need to determine the reflection of f(x) over the x - axis

<u>Reflection over x - axis:</u>

The translation rule to reflect over the x - axis is given by

$(x, y) \rightarrow(x,-y)$

Reflecting the function over the x - axis, we get;

$-y=\frac{3}{7}(2)^{x}$

Multiplying -1 to both sides of the equation, we have;

$y=-\frac{3}{7}(2)^{x}$

This can be written as

$g(x)=-\frac{3}{7}(2)^{x}$

Hence, the reflection of the function over the x - axis is $g(x)=-\frac{3}{7}(2)^{x}$

Thus, Option A is the correct answer.
