Answer:
x. = sqrt 6 and x = - sqrt 6
Step-by-step explanation:
x^4 + 2x^2-48=0
(x^2 - 6) (x^2 + 8) = 0
x^2 - 6 = 0
x = + sqrt 6 and x = - sqrt 6
x^2 + 8 = 0
x^2 = sqrt -8 (a negative number doesn’t have a real square root)
I'm missing some information... but I'll answer the question regardless
x=the cost of the meal
1.2x≤$15
divide both sides by 1.2
x≤$12.5
In short, this means that Nicole can buy anything that costs $12.50 or less.
First divide 6,513 by 10.
Second look at the place value the 5 is in.
The 5 represents the tens place or 50.
I hoped this helped!
Answer:
Step-by-step explanation:
The constant of direction variation givens a proportion that is maintained by both x and y values for all points of a line that it passes through.
Usually represented with the variable 
, it is given by:
for coordinates (x, y).
This relationship can be written as 
which is also the layout for a proportional relationship.
Since coordinates are written (x, y), for point (5, 8), substitute 
to get the constant of variation:
