Answer:
10x - 5(x - 1) = 20
10x - 5x + 5 = 20
5x + 5 = 20
5x = 20 - 5
5x = 15
x = 15/5
x = 3
Step-by-step explanation:
Answer:
The equation of the line that is parallel to given line and passes through the point (-8, -3) is: 
Step-by-step explanation:
Given equation of line is:

The general form of equation of line in slope-intercept form is written as:

Here m(co-efficient of x) is the slope of the line and b is the y-intercept.
Comparing the given equation with the general form we get
m = 5
Two parallel lines have same slope so the slope of any line parallel to given line will also be 5.
Let m1 be the slope of required line parallel to y=5x-3
Then m1=5
Putting in general form


To find the value of b(y-intercept) the given point has to be put in the equation from which the line passes.
The point is (-8,-3)

Putting the value of b and m1, we get

Hence,
The equation of the line that is parallel to given line and passes through the point (-8, -3) is: 
What graph are you talking about:? can you give a pivture
The derivative of
is defined by the limit,

In this case,
, so the derivative would be

Simplifying the numerator gives

The numerator and denominator share a common factor of
, which we can cancel because
means that we're considering
so that
:

Then as
, we're left with the derivative
