Answer:
C. since 8, 15, 17 are pythagorean triples
Always follow the rules of BOMDAS. (If you don't know them or maybe learned differently tell me).
Firstly multiply 4(1/2) and then substract
8 - 4(1/2)
8 - 2
6
Hope this helps :).
<span>A direct variation is of the form
y = kx
where k is the constant of variation
In most cases k is positive in which case
y increase in direct proportion to an increase in x
Example
k = 2
x = 1, y = kx = 2(1)= 2
x = 3, y = kx = 2(3) = 6
Occasionally k is negative in which case
y decreases in direct proportion to an increase in x
Example
k = -2
x = 1, y = kx = (-2)(1) = -2
x = 3, y = kx = (-2)(3) = -6
---------------------------
This is not to be confused with an indirect variation which is of the form
y = k/x
where k is the constant of variation
Example
When k is positive y decreases inversely as x increases
k = 2
x = 1, y = k/x = 2/1 = 2
x = 3, y = k/x = 2/3 = 2/3
When k is negative y increases inversely as x increases
k = -2
x = 1, y = k/x = -2/1 = -2
x = 3 y = k/x = -2/3 = -2/3</span>
Answer:
1239.1
Step-by-step explanation:
x + y = z
x = 789.4 (your money)
y = 449.7 (Your mom's money)
z = Total amount of money.
789.4 + 449.7 = z
789.4 + 449.7 = 1239.1
z = 1239.1
No it doesn't.
When x=2,
x + 2 = 4
and
x² + 4 = 4 + 4 = 8
If you want (x + 2) to be equal to (x² + 4),
then
either x = 0.5 + 1.323 i
or
x = 0.5 - 1.323 i . ' i ' = √-1
There are no other ways to do it.
