Answer:

Answer:

It can be A. (not B or C)

Step-by-step explanation:

It is A because x-6=0 can be simplified to x=6. Then, 2x + 6, you can divide the whole equation resulting in x+3=0, simplify this and you get x=-3. YES

It is not B because, while x+3=0 results in a zero of -3, 6x-1 can be simplified to be divided by 6. When we do this we get x-1/6=0, which is not equivalent to 6. NO

It is not C because, while x-6=0 results in a zero of 6, -3x can be simplified with the zero product property to get -3x=0 then dividing -3 by 0 giving you 0 which is not equivalent to one. NO

gregori [183]

Differentiate using the exponential rule, which determines that $\bf{\frac{d}{dx}[a^{x}] }$ is $\bf{a^{x} \ In(a) }$ when a=3.

$\boldsymbol{ 3^{x} \ In(3) \ \to \ \ \ Answer }$

Therefore, the correct option is "E". You just have to remove the parentheses.

Perform the indicated operation: (-1 1/2)(-3/2)

LiRa [457]

Answer:

=8 1/4 as a fraction or 8.25 in decimal form.

Step-by-step explanation:

The indicated operation is the product of the two fractions. Multiplication opens the brackets.

(-11/2)×(-3/2)

=(-11×-3)/(2×2)

=33/4

The negative signs before each term cancel out in multiplication and division.

=33/4 =8 1/4= 8.25

Choose 1 answer among the improper fraction, Mixed fraction or the decimal.

Given a right ?ABC, where AB = 4.5 cm, BC = 7.794 cm, and AC = 9 cm, sketch the triangle below, and find the measure m?C in degr

Ksju [112]

Answer:

The measure of angle C is $30\°$

The draw in the attached figure

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABC

The sine of angle C is equal to divide the opposite side to angle C by the hypotenuse

$sin(C)=\frac{AB}{AC}$

substitute the values

$sin(C)=\frac{4.5}{9}$

$C=arcsin(\frac{4.5}{9})=30\°$
