2 is the only right answer. If it has right/left symmetry, then f(-x) = f(x), meaning it's even.
extra info: 3 and 4 are the same thing
5 works for odd functions (like sin(x))
Answer:
y = -7/5x
Step-by-step explanation:
First, we need to use the two points to find the slope.
m = y₁ - y₂ / x₁ - x₂
m = -7 - 0 / 5 - 0
m = -7/5
Now we know that the slope is -7/5. Now we'll substitute the information we've gathered into the point-slope form equation to get an equation.
y - y₁ = m(x - x₁)
y - (-7) = -7/5(x - 5)
y + 7 = -7/5x + 7
y = -7/5x
Therefore, the equation of the line is y = -7/5x.
Answer:
A) 150
B)30
Step-by-step explanation:
Answer:
x = 
, y = 
Step-by-step explanation:
Express as 2 equations, that is
x + y = 1 → (1)
- x + 9y = 1 → (2)
Add the 2 equations term by term to eliminate x, that is
10y = 2 ( divide both sides by 10 )
y = 
=
Substitute this value into (1) and solve for x
x + = 1 ( subtract from both sides )
y = 
- =
- First multiply 1/3 times 1/6 across giving you 1/18
-then get the LCD of 5/9 and 1/18 which is 18
multiply 5/9 times 2/2 to get 10/18.
-Now you can subtract
10/18- 1/18 = 9/18
-further simplify by diving the top and bottom of 9/18 by 9
the answer would be =1/2
<em>*Note: you do not need to get the LCD of a fraction when multiplying or dividing. You DO need the LCD when adding or subtracting a fraction.</em>
