(3,6). 3 units from point. 6 units from y axis.
Answer:
Probability of an event must be from 0 to 1.
Here,6/5 is more than 1 i.e. 1.2.
Hence,the answer is incorrect.
Answer:
(5x+3)/2
Step-by-step explanation:
f(x)=(2x-3)/5
f(x)=y
y=(2x-3)/5
interchanging role of x and y
x=(2y-3)/5
5x=2y-3
5x+3=2y
y=(5x+3)/2
the inverse if f(x) = (5x+3)/2
Answer:
(x) = √ x + 4
Step-by-step explanation:
step 1) replace f(x) with y
y = x² - 4
step 2) switch the x and y (because every (x, y) has a (y, x))
x = y² - 4
step 3) add 4 to both sides of the equal sign
x + 4 = y²
step 4) take the square root of both sides of the equal sign (the square root symbol cancels out the ²)
√ x + 4 = y
step 5) you know have the inverse of f(x) = x² - 4
(x) = √ x + 4
Ans: (c)
y = k/x^2
when y = 100, x = 1
100 = k/1^2
k = 100
when x = 2,
y = 100/2
= 50
(u/rachelmarrons already gave you the answer but here’s a step-by-step explanation in case you needed it haha)
