• Move x to the other side
7y=21-3x
• Divide by 7
y = (21-3x)/7
Answer:
The graph in the attached figure
Step-by-step explanation:
Let
x-----> the number of pints
y----> the number of servings
For x=3 pints, y=2 servings
This is a proportional variation
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
or 
so
The linear equation is equal to
The graph in the attached figure
Answer:
Step-by-step explanation:
Exponents with fractions in them are really just radical notation in a different form. You've probably seen the square root sign.
That can be written as
x^(1/2)
...and when you take an even root of a negative number, there is no real answer. (2 is an even number).
Looking at the answer choices here, we can see that B and D use even roots, so they will give non-real answers.
So, A and C are the answer choices to select.
21 is the answer i think idk try dividing them all or finindng something or look up how to find a standard deviation
