Answer:
x = -1.7, or x = -17/10
Step-by-step explanation:
f(x) = 9.2 + 6x + 1 is a linear function and as such (and because the slope is not zero) has only one solution. Combining like terms, we get
f(x) = 10.2 + 6x = 0 (you must set this equal to zero if solving for zero(s).
Then 6x = -10.2, and x = -1.7, or x = -17/10
The answer is 4
c(8)=1/4(8)+2
c(8)=2+2
c(8)=4
hope this helps !
Answer:
w=-9
Step-by-step explanation:
14-9=5, but this is addition, so you must do a negitive
-9+14=5
Step-by-step explanation:
a refuse regular function tries to calculate a y value for a given x (input) value.
the inverse function turns this around and tries to calculate the x (input) value for a given y functional value.
e.g. when we know f(x) = 8, then what was the x value leading to this 8 fungible value ?
in order to turn this around, we solve the same functional equation for x instead of for y.
in our example here
f(x) = y = 3x -6
y + 6 = 3x
x = y/3 + 2
and now, to write the inverse function as normal function, we simply exchange the x and y names :
y = x/3 + 2
The answer should be -10c and -20c
