Answer: Small number = 15.
Larger number = 20
Step-by-step explanation:
Let the smaller number be x.
The larger of two numbers is five more than the smaller. Thus, the larger number is x+5.
Twice the larger is twenty less than four times the smaller. This can.be written as:
2(x + 5) = 4x - 20
2x + 10 = 4x - 20
2x - 4x = -20 - 10
-2x = -30
x = 30/2
x = 15
The smaller number is 15
Larger number = x + 5 = 15 + 5 = 20
First of all, if we want to graph this we will need to make it into slope intercept form
2x - y = 3
add y to both sides
2x = y + 3
subtract 3 from both sides
2x - 3 = y
flip the equation
y = 2x -3
we now know that the y-intercept is at (0, -3)
using that we plot the first point
The slope is 2
(this means up 2 over 1)
using that we make a line
(I'm sure you can graph it ;D)
Hope this helps :)

Answer:
it is irrational because the square root is a series numbers whereas a rational number can be expressed as a fraction (recurring and terminating decimals) but irrational numbers can't be expressed as a fraction
