Y=3x-1
y=3(-1) - 1
y= -3-1
y=-4
the answer is B.-4
Answer:
The function through which given point passes is f(x) = 24 x - 12 .
Step-by-step explanation:
Given as :
The points are
, 
= 1 , 12
, 
= 2 , 36
now, slope of the line
Let The slope of line = m = 
Or, m = 
Or, m = 24
So The slope of line = m = 24
<u>Now, equation of line in point-slope form</u>
y - = m × (x - )
Or, y - 12 = 24 × (x - 1 )
or, y - 12 = 24 x - 24
or, y = 24 x - 24 + 12
or, y = 24 x - 12
or , f(x) = 24 x - 12
So, The function through which given point passes is f(x) = 24 x - 12 . Answer
The inverse of the given function is y = √5x + 7/2 - 3
<h3>Inverse of a function</h3>
Given the function expressed below;
5y + 4 = (x+3)² +1/2
5y = (x+3)² - 7/2
y = 1/5(x+3)² - 7/10
Replace y as x
x = 1/5(y+3)² - 7/10
Make y the subject of the formula
5x = (y+3)²- 7/2
(y+3)² = 5x + 7/2
y+3 = √5x + 7/2
y = √5x + 7/2 - 3
Hence the inverse of the given function is y = √5x + 7/2 - 3

#SPJ1
Answer: C
Step-by-step explanation: C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
Total: 1000
20 had fever, so 1000 - 20 = 980 who did not have fever
Total who did not have fever: 980
As 880 not fever and not inflamation, 980 - 880 = 100
So, 100 had inflamation but not fever.
We need the 2 statements and they alone do not answer the question
Let there exists a point (x, y) on the given line.
Slope of all points must be same, as they lie on the same line.
=> (y - 1)/(x - 2) = (4 - 1)/(-4 - 2)
=> (y - 1)/(x - 2) = - 1/2
=> y - 1 = (-½) (x - 2)
Option 1 is the correct option
