Answer:
2.8574142
Step-by-step explanation:
Multiply it out first.
90x+225-4=1
Combine like terms.
90x+221=1
Start isolating variable.
90x=-220
x=-220/90=-22/9
The answer is x=-22/9.
Hope this helps!
Answer:
Yes it is in fact a function.
Step-by-step explanation:
Since there is one value of y for every value of x in the question
y = 1/3x
The slope is 1/3 ( the slope is the number with the variable x).
There is no other operation ( addition or subtraction) so the y- intercept is 0
The first point of the graph would be (0,0)
Calculate another point , lets use x = 3
y = 1/3(3) = 1
The second point is (3,1)
The line of the graph is an angled line which is located in quadrant 1 and 3.

Answer:
n = 11/3
Step-by-step explanation:
n = certain number
6n - 1 = 21
6n = 22
n = 22/6 or 11/3
