Answer:
The arrangement of the given equation in the slope - intercept form are
Step-by-step explanation:
Given:
x + y = 4 and
y - 2x = -5
Slope - intercept form :
Where,
m is the slope of the line.
c is the y-intercept.
When two points are given say ( x1 , y1 ) and ( x2 , y2) we can remove slope by
Slope,
Intercepts: Where the line cut X axis called X- intercept and where cut Y axis is called Y- intercept.
So, the Slope -intercept form of
x + y = 4 is
and
y - 2x = -5 is
In order to find x-axis interception coordinates you need to set other two variables (y and z) to zero and solve the remaining equation.
So the following simple equations need to be solved:
2x = 40
5y = 40
-4z = 40
It intercepts x-axis at coordinates (20;0;0), y-axis at (0;8;0) and z-axis at (0;0;-10).
SOLUTION
The given equation is
From the given graph, one of the solution of the equation is
Since x=4 is a solution to the equation it follows that x-4 is a factor
The given equatin can be simplified as
Therefefore other solutions are
Step-by-step explanation:
x⁴(4x+1)
4x⁵+x⁴
degree is 5
So investment is $140 and interest is 3% per yea
yo convert % to number 3/100 = .03
so for one year. $140 x .03 = $4.20/year
in two years you have $4.20+$4.20 =$ 8.40!
Answer is $8.40 or 2 years
