F(x) = 4 - 2x Domain = x = -4, 0, 5
f(x) = 4 - 2(-4) = 4 - (-8) = 12
f(x) = 4 - 2(0) = 4 - 0 = 4
f(x) = 4 - 2(5) = 4 - 10 = -6
f(x) = 12, 4, -6
The range is C.
Answer:
the answer is 5
Step-by-step explanation:
2x/5 - 9 = -7
2x/5 = -7 + 9
2x/5 = 2
2x = 2 * 5
2x = 10
x = 10/2
x = 5

Answer:
A
Step-by-step explanation:
- The values must decrease
- x∧12≥3x∧7≥4x³≥9x
Let me help you with this :)
John = x
Mike = y
x = 4 + 3y (4 more than 3 times)
x + y = 20 (we put the x above into this equation)
4 + 3y + y = 20
4y = 16 (we transfers the 4 on the left side to the right side and subtract it from the 20)
y = 4 (the answer is 4)
we use this for the equation:
x = 4 +3*4
x = 16
John is 16 years old and Mike is 4 years old :)
