Answer:
y was not substituted for every x
Step-by-step explanation:
To find the inverse of ...
y = f(x)
you need to solve ...
x = f(y)
Here, f(x) = x^2 +12x, so f(y) = y^2 +12y
This is not the expression we see on the right of ...
x = y^2 +12x
Apparently y was not properly substituted into f(x).
-2 is 5 less than 3
hope this helps
Answer:
x = 4
Step-by-step explanation:
6x - 8 = 4x
-6x -6x
-8 = -2x
-----------
-2
x = 4
Look like a linear equation. let's try finding the slope:
(7-4)/(1-0)=3
(4-1)/[(0-(-1)]=3
[1-(-2)]/[-1-(-2)]=3
indeed, it is linear, with a slope of 3
when x=0, y=4, so the y intercept is 4
the equation of the line is y=3x+4
Two squares is correct. A square is always similar to another square because its ratio of side lengths is always 1 to 1 and it is always 4 sided with all interior angles being the same (90 degrees).
