Answer:
4 sqrt(3) = x
Step-by-step explanation:
We have similar triangles
The ratios of the sides have to be in proportion
The large triangle has sides x and hypotenuse 12
The small triangle has side 4 and hypotenuse x
We can write the ratio of sides to hypotenuse
x 4
---- = -------
12 x
Using cross products
12*4 = x^2
48 = x^2
Taking the square root
sqrt(48) = sqrt(x^2)
sqrt(3*16) = x
sqrt(16) sqrt(3) = x
4 sqrt(3) = x
Y=2/3x -4 . First, you look for the y when x=0. Then you try to find the best variation
Answer:
No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to call the numbers x and y.
A number is equal to twice a smaller number plus 3.
Greater number is x, and smaller is y. So

The same number is equal to twice the sum of the smaller number and 1.
This means that 
Equaling the values for x:



Since division by 0 does not exist, it means that there is no solution for the system.

Answer:

Step-by-step explanation:
Given


Required
Determine an equation that perpendicular to the equation
An equation has the form:

Where

By comparison:

Next, we determine the slope of the new line.
When two lines are perpendicular, the following relation exist:

Substitute 1/5 for m1


The equation of the line is then calculated using:

Where:
and 
This gives:
