Answer from: MilanPatel

Step-by-step explanation:

The given expression is 10x .

We have to check which of he given options on simplification gives the same given expression.

(A) The expression is:

= $\frac{50x}{5x}$

which is not equivalent to the given expression, thus this option is incorrect.

(B) The expression is:

= 10(10x)-1

= 100x-1

which is not equivalent to the given expression, thus this option is incorrect.

= 10(10x)+1

= 100x+1

which is not equivalent to the given expression, thus this option is incorrect.

(D) The expression is:

= $\frac{50x}{5}$

= 10x

which is equivalent to the given expression, thus this option is correct.

(E) The expression is:

= $(\frac{50}{5})x$

== 10x

which is equivalent to the given expression, thus this option is correct.

(F) The expression is:

= x^5

which is not equivalent to the given expression, thus this option is incorrect.

Answer from: lillysiege

The correct options are ${\text{A} = {\left( {9 \cdot 9} \right)^x},C = {9^x} \cdot {9^x}{\text{ and }}F = {9^{2x}}.$

Further explanation:

The associative property is defined as a grouping of multiplication, addition, subtraction and division.

Always use the PEDMAS rule to solve the grouping of multiplication, addition, subtraction and division.

Here, P is parenthesis, E is exponents, M is multiplication, D is division, A is addition and S is subtraction.

Given:

The expression is 10x.

The options are as follows,

(A). $\dfrac{{50x}}{{5x}}$

(B). $10 \cdot 10x - 1$

(C). $10 \cdot 10x + 1$

(D). $\dfrac{{50x}}{5}$

(E). $\left( {\dfrac{{50}}{5}} \right)x$

(F). ${x^5}$

Explanation:

The expression 10x can also be written as follows,

Solve option (A).

$\dfrac{{50x}}{{5x}} = 10$

Option (A) is not correct.

Solve option (B).

$10 \cdot 10x - 1 = 100x - 1$

Option (B) is not correct.

Solve option (C).

$10 \cdot 10x - 1 = 100x - 1$

Option (C) is not correct.

Solve option (D).

$\dfrac{{50x}}{5} = 10x$

Option (D) is correct.

Solve option (E).

$\left( {\dfrac{{50}}{5}} \right)x = 10x$

Option (E) is correct.

Solve option (F).

${x^5}$

The correct options are $D=\dfrac{{50x}}{5}{\text{ and }}E = \left( {\dfrac{{50}}{5}} \right)x.$

Option A, B, C and F are not correct.

Answer from: Quest

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

Answer from: Quest

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6 = 0.00000180

1.80 x 10-4 = 0.000180 (bigger, or "less small", than the former one)

1.8 x 10-2 = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

Use the spider tool located on page 1 of this activity to draw a 12-pointed star for the new logo. (hint: if the spider rotates 360 degrees -- or 720 degrees or 1080 degrees -- she will be facing in the same direction in which she started. when the spider is done drawing, you want her to be facing in the same direction in which she started. she'll be making 12 rotations, all the same size, so each rotation must be some multiple of 360/12 = 30 degrees.) urgently. been stuck on this problem for around 45 minutes now.! it should be easy if you're smart enough
