Answer:
The lines are parallel
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
Remember that
If two lines are parallel, then their slopes are the same
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
step 1
Find the slope JK
we have
substitute the values
step 2
Find the slope LM
we have
substitute the values
step 3
Compare the slopes
so
therefore
The lines are parallel
Answer:
y = -6 * x^3
Step-by-step explanation:
We can model the new function as:
f(x) = ax^3
the function y = x^3 have positive values of y for positive values of x, and negative values of y for negative values of x.
As the negative values of x have positive values of y and vice-versa, the first change is to put a negative sign in front of x^3, so we know that 'a' is negative.
Then, for x=1 we have y = -6, so:
-6 = a*1^3
a = -6
So the equation of the transformed function is:
y = -6 * x^3
You just use what you already know. You know that 1 week is equal to 7 days so you just do 1 * 7 = 7 or 1 week. Then 54 * 7 = 378
You basically plug in the x in the equation, for example if x = 4 and the equation is y = 2x + 5 you plug in 4 and the equation becomes y = 2(4) + 5. you then multiply and get y=8+5. from here u just add it and u get ur answer
