Answer:
you can use the cikg method
1,2,4.5,60.5, 1/2 are all rational
pi, e, sq rt(2) are all irrational.
rational numbers can be out in fraction form while the irrational numbers are infinite
Answer:
The inverse function is 3x+2
Step-by-step explanation:
To get the inverse function exchange x and y and then solve for y
y = (x-2)/3
Exchange x and y
x = (y-2)/3
Solve for y
Multiply by 3
3x = 3/3 *(y-2)
3x = y-2
Add 2 to each side
3x+2 = y-2+2
3x+2 =y
The inverse function is 3x+2
The answer is radical 26. Since the triangle is right (given) you can use Pythagorean’s theorem (a^2+b^2=c^2) so in this case: c^2= 1+25=26 and you square root both sides to get rid of the ^2 and you get radical 26.
Option B is correct
Why
3x=21
3(7) =21
21=21
