X - y = -3
x - x - y = -3 - x
-y = 3 - x
y = -3 - x
Answer:
Step-by-step explanation:
The function is given :
f(x) = 4x + 15
For f(-3), the input for the function f(x) is -3.
Replace the x variable with -3.
f(-3) = 4(-3) + 15
Evaluate.
f(-3) = -12 + 15
f(-3) = 3
The output for f(-3) is 3.
Answer: x≥14/3
Step-by-step explanation: Hope this help :D
3/7 = 0.43 (approx.)
4/9 = 0.44 (approx.)
Hence, 4/9 is bigger.
Answer: The freezing temperature of water in degrees Fahrenheit is 32.
Step-by-step explanation:
Hi, to answer this question we have to replace the value of the variable "C" in the formula F(C), by the value given in Celsius that water freezes.
Mathematically speaking:
F(C) = 32 +1.8 C
F (0) = 32 +1.8 (0)
Solving for F (Fahrenheit), since any number multiplied by zero equals zero:
F = 32
The freezing temperature of water in degrees Fahrenheit is 32.
