Answer:
Step-by-step explanation:
To find the inverse of a function, simply switch the 'x' and 'y' variables. Substitute in 'y' in the place of f(x) for this purpose:
y = 2x - 10
Switch positions:
x = 2y - 10
Add '10' to both sides to begin simplifying:
x + 10 = 2y
Divide both sides by 2:
This can be rewritten as:
Therefore, the inverse of the function is:
Answer:
200 days
Step-by-step explanation:
2m=120+1.4m
0.6m=120
m=200
divide by 0.6
The zeroes of the polynomial are the values of x that will make the f(x) = 0.
0 = x^2 + x - 6
Use factoring,
0 = (x + 3) (x - 2)
x + 3 = 0 and x - 2 = 0
Thus, the values of x are <em>x = -3</em> and <em>x = 2</em>.
3.4^2 - 1.6^2= 9
square root of 9 is 3
the missing length is 3
Answer:
it's a reduction because it's smaller than the original shape
Step-by-step explanation:
(a reduction means the new shape is smaller than the original, and an enlargement means the new shape is bigger than the original one)
