Answer:
f⁻¹(x) = x/4 + 1/2
Step-by-step explanation:
To find the inverse of a function, switch the x and y variables, then isolate y.
f(x) replaced y, so you can replace it back.
y = 4x - 2
x = 4y - 2 Switched x and y
x + 2 = 4y Added 2 to both sides
y = x/4 + 2/4 Divided both sides by 4
y = x/4 + 1/2 Simplified
f⁻¹(x) = x/4 + 1/2 Use function notation
Answer: D
80 000 > 0,00004
80 000 : 0,00004 = 2 000 000 000
2 000 000 000 = 2*10^9
They are not similar because BR: DB is 1:2 and KE:YK is 1:3. This is due because of the slope, the slope of KE:YK is 9/3 or 3/9 which is equal to 1:3 and the slope for BR:DB is 2/4 or 4/2 which is how you get the ratio of 1:2.
Answer:
4/5
Step-by-step explanation:
The ratio 8:10 represents 8/10 so if we simplify it the answer will be 4/5
