Answer:
the expression is x= 2.5 * z/√y
Step-by-step explanation:
since x is proportional to z and since x varies inversely as the square root of y
x= a * z/√y
then
a = x*√y /z
replacing values
a = x*√y /z = 6*√25 /12 = 30/12 = 10/4=2.5
therefore
x= 2.5 * z/√y
Answer:
375
Step-by-step explanation:500 equals 100% divide by 4 its 125 times 3 equals 375, your welcome
Answer:
First, this table is a function because it has no repeating input values
Second, it is increasing in both the x and y
third, since it is increasing in x and y it is a positive correlation( I dont know if you have learned that yet)
Fourth, the output increases by 4 each time the input increases by 1
Step-by-step explanation:
(5,1). you have to find the opposite of the x-coordinate. <span />
Hey there :)
f (x) = 5x² - 2x
g (x) = 3x² + x - 4
( f + g )( x ) is f ( x ) + g ( x )
5x² - 2x + 3x² + x - 4
Combine like-terms
5x² + 3x² - 2x + x - 4
8x² - x - 4
Your option will be the third option
