F(x) = (-1/2) * (x-3)
y = (-1/2) * (x-3)
⇒ -2y = x - 3
⇒ -2y + 3 = x
⇒ x = -2y + 3
Thus f^-1(x) = -2x + 3
Answer:
Step-by-step explanation:
+(+) Two like signs become a positive sign 3+(+2) = 3 + 2 = 5
−(−) 6−(−3) = 6 + 3 = 9
+(−) Two unlike signs become a negative sign 7+(−2) = 7 − 2 = 5
−(+) 8−(+2) = 8 − 2 = 6
Answer:
Step-by-step explanation:
First question
1 solution
- 6p-12= - 5p Take 6p from both sides
- -12 = -5p - 6p Combine
- -12 = - 11p Divide by - 11
- -12/-11 = p
- 1.09 = p
Second Question
- Infinitely many solutions.
- 5p + 10 = 5p + 10
- No matter what value you use for p, the right side of the equation always equals the left side.
Third question
- y = 25 - 2x
- x = 6
- y = 25 - 2*6
- y = 25 - 12
- y = 13
There are 13 more stops to make.
Answer:
f(x) = 7
Step-by-step explanation:
In an even function of x, all powers of x are even (2, 4, 6, etc.).
In this case we have f(x) = 7, or 7x^0, which is an even function because the power (0) of x is even.
