Vary Directly: y = k*x
Vary Inversely: y = k/x
Because x and y vary directly, our equation will look like the first one.
y = k*x
With the inputted values:
-16 = k * 4
Now, to find k, isolate the variable
k = -16/4 = -4
Your final equation will then look like this:
y = -4 * x
Answer:
Step-by-step explanation:
We have
and
We want to find (f+g)(x).
By the algebraic properties of polynomial functions,
This simplifies to
We can't simplify further, hence the simplest form
Answer:
The slope is 2 and the y intercept is -7
Step-by-step explanation:
y = -7 + 2x
Rearranging
y = 2x -7
This is in the form y = mx+b where m is the slope and b is the y intercept
m = 2 and b = -7
Answer: 10.2
Step-by-step explanation:
b = 15² - 11²
= 225 - 121
= 104
= √104
= 10.2
Answer:
b . all of the other ones look the same and that one is the different one
