Answer:
Step-by-step explanation:
-7x = x² + 12
Set equation to zero:
x² + 7x + 12 = 0
Quadratic formula:
x = [-7±√(7²-4·1·12)]/[2·1]
= [-7±√1]/2
= -3,-4
The zeros are -3 and -4
Answer:
#1) -3 feet
#2) 5hours
Step-by-step explanation:
#1) you need to find the rate of change- feet per minute
To find the rate, divide -12 feet by 4 minutes (the twelve in negative because it decreases, almost like subtraction)
-12/4= -3 feet per minute.
Now, multiply by amount of minutes- -3x1= -3 feet in 1 minute
#2) To find the maount of degrees each hour,
divide 10 degrees by 2 degrees per hour.
10/2=5 hours

Answer:
0
Step-by-step explanation:
Here, given the function f(x), we want to calculate f(1)
Mathematically, this means we shall substitute 1 for the value of x in that function.
Thus, given F(x) = 1-x
Then F(1) would be = 1-1 = 0
