For this case we must simplify the following expression:

$\frac {3- \frac {2} {a}} {5+ \frac {3} {a}}$

So, we have:

$\frac {\frac {3a-2} {a}} {\frac {5a + 3} {a}} =$

We apply double C:

$\frac {a (3a-2)} {a (5a + 3)} =$

We simplify:

$\frac {3a-2} {5a + 3}$

Answer:

The simplified expression is:

$\frac {3a-2} {5a + 3}$

See below:

Step-by-step explanation:

Hello! I hope you are having a nice day.

We can solve this equation in a single step, we just need a bit of theory and a graph.

We can first see that its in $y=mx+b$ form. Which is also known as Slope-Intercept form.

This means that we know the following.

$b$ is the y coordinate of the y intercept.
$m$ is the slope of the line.

Since we know that, we can see that from our equation that the slope of the line is 3 and the y intercept is (0,-7).

Now that we've gotten that, we can start graphing.

The y intercept is -7 so we can plot (0,-7) as one of our points.

The slope of 3 means that we got up 3 units then right a single unit.

Therefore, another point could be (1,-4).

With our two points, we can create our graph by creating a straight line through those two points and therefore plotting our line.

Cheers!

Write the slope intercept form of the r question of the line parallel to the graph of 2x+y=5 that passes through (0,1)

Fofino [41]

Step-by-step explanation:

first let's get the original line in slope intercept form.

the vegetal slope intercept form is

y = ax + b

a is the slope, b is the y-intercept.

2x + y = 5

y = -2x + 5

there !

a line parallel to this line must have the same slope (-2).

but it will intersect with the y-axis at a different point.

the y-intersect is the y value when x = 0.

the given point (0, 1) is already that y-intersect (because x=0).

so, the desired parallel line function is

y = -2x + 1

if we had a different point of the line, e.g. (4, -7), we would go back to the general equation

y = ax + b

put in the slope we know (-2)

y = -2x + b

and then put in the x and y cakes if the point and calculate b

-7 = -2×4 + b

-7 = -8 + b

b = 1

and then we get again

y = -2x + 1

$\large \mathfrak{Solution : }$

let's solve for x :

$\dfrac{2}{9} x - \dfrac{1}{3} = - 1$

$\dfrac{2}{9} x = - 1 + \dfrac{1}{3}$

$\dfrac{2}{9} x = \dfrac{ - 3 + 1}{3}$

$x = \dfrac{ - 2}{3} \times \dfrac{9}{2}$

$x = - 3$

I hope it helped...
