Answer:

-2(3-2x) Given,

-6+4x: Distributive property,

-6+3x: Subtraction property of order,

3x: Addition property of order,

x: Division property of order.

Step-by-step explanation:

We have been given an inequality. We are asked to match each step for solving the equation with reason.  

-2(3-2x)

Using distributive property, we will get:

-2\cdot3-(-2)\cdot2x

-6+4x

Subtract x from both sides:

-6+4x-x

-6+3x

Add 6 on both sides:

-6+6+3x

3x

Divide both sides by 3:

\frac{3x}{3}

x

ikadub [295]

Answer: The least number of minutes that he has used his phone in a month is 1248

Step-by-step explanation:

Let m represent the number of minutes that he used his phone in a month.

For his phone service, Michael pays a monthly fee of $16, and he pays an additional $0.04 per minute if use. This means that if he used m minutes in a month, the total cost would be

16 + 0.04m

The least he has been charged in a month is $69.52. This means that

16 + 0.04m ≥ 65.92

0.04m ≥ 65.92 - 16

0.04m ≥ 49.92

m ≥ 49.92/0.04

m ≥ 1248 minutes

Why is this number not in scientific<br> notation?<br> 36.5 x 10^6<br> please help
andrew11 [14]

Answer:

The first number should be a number between 1 and 10 (see explanation)

Step-by-step explanation:

For a number to be in scientific notation, a number between 1 and 10 has to be multiplied by a power of 10.

36.5 is not between 1 and 10, alternatively, you can rearrange it:

3.65 x 10^7      <----This would be the correct scientific notation

Sonja plays tennis and started a tournament with 43 aces on the season. The graph relates her total season aces with the number
Pani-rosa [81]
<h2>Answer</h2>

-6x+y=43

<h2>Explanation</h2>

The first thing we need to do is find the slope of our line. To do it we are using the slope formula:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

where

m is the slope of the line

(x_{1},y_{1}) are the coordinates of the first point on the line

(x_{2},y_{2}) are the coordinates of the second point

From our graph we can get the points (0, 43) and (2, 55), so x_{1}=0, y_{1}=43, x_{2}=2, and y_{2}=55. Let's replace the values in our slope formula:

m=\frac{55-43}{2}

m=\frac{12}{2}

m=6

Now that we have our slope, we can use the point-slope formula:

y-y_{1}=m(x-x_{1})

y-43=6(x-0)

y-43=6x

But remember that the equation of a line in standard form is Ax+Ay=C, so we need to subtract 6x and add 43 to both sides of our point slope equation:

y-43=6x

-6x+y-43+43=6x-6x+43

-6x+y=43

We can conclude that the equation in standard form that represent the relationship in the graph is -6x+y=43.
