The value of x is 200

The number of texts is 1000

<h3>How to determine the values</h3>

We have that:

1/ 5x - 2/3 y = 30

Where y = 15

Now, let's find the LCM

3x - 10y/ 15 = 30

cross multiply

3x - 10y = 450

substitute the value of y

3x - 10(15) = 450

3x - 150 = 450

collect like terms

3x = 450 + 150

3x = 600

x = 600/ 3

x = 200

To determine the number

$0. 05 is the cost per text

Base cost is $5

Limit is $25

= 25/ 0. 05 + 5

= 25/ 0. 025

=1000

Thus, the value of x is 200 and number of texts is 1000

Find the equation of the line shown
solniwko [45]

Answer:

y=-\frac{1}{4}x+2

Step-by-step explanation:

We will use the point slope formula: y=mx+b

We will start by finding the slope(m).
The formula for slope is

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

So if we just choose 2 random points on the line:

I choose (0,2) and (4,1), we get:

\frac{1-2}{4-0} = \frac{-1}{4}

That's our slope.

Next we need to find the y-intercept(b). We can find that by looking at the graph. It is where x=0. So in this case y=2 when x=0.

So in point-slope form the equation is:

y=-\frac{1}{4}x+2

Simplify the following
Bond [772]

Answer:

Step-by-step explanation:

1) 5xy - xy + 2x - 13x + 10xy - 8x =<u> 5xy - xy + 10xy</u>   +<u>2x - 13x - 8x</u>

Combine like terms

 =  (5 -1 +10)xy + (2-13-8)x

 = 14xy + (-19x)

 = 14xy - 19x

2) -6c - (-6c) - (+6c) = -6c + 6c - 6c

                               = (- 6 + 6 - 6)c

                                = -6c

3) 0x - 22x - 4(2x) = 0x - 22x - 8x = -30x
