Answer:
2(2y - 1) - y = 7
Step-by-step explanation:
I guess the 2 equations are
2x - y = 7
x = 2y - 1
substitution message that you use one equation to express one variable by the other, and then you use that in the other equation to get one equation for one variable. then you solve for that, and use that result in the first equation to since for the second variable.
the equations are already defined that way, that the second equation directly defines x as an excision of y.
so, this needs to be used then in the first equation.
and that makes
2(2y - 1) - y = 7
the correct first step.
Answer: C. 
=======================================================
Explanation:
The x intercept always occurs when y = 0.
Use the unit circle to determine that 
when 
So if 
, then we have
which shows us that 
is the location of one of the infinitely many x intercepts for this function.
Answer:
f(2) = g(2) and f(0) = g(0)
Step-by-step explanation:
When x = x in f(x) and g(x), that means the two functions are equal.
34 is the answer to 4 1/4 to 1 1/8
To have all positive terms I think
