Answer:
The inverse is (x^2-5)/2
Step-by-step explanation:
y =sqrt(2x+5)
Exchange x and y
x = sqrt(2y+5)
Solve for y
Square each side
x^2 = (sqrt(2y+5))^2
x^2 = 2y+5
Subtract 5 from each side
x^2 -5 = 2y-5+5
x^2 -5 = 2y
Divide each side by 2
(x^2-5)/2 = 2y/2
(x^2-5)/2 = y
The inverse is (x^2-5)/2
Answer:
The length of W'X' will be exactly given by, 12 unit.
Step-by-step explanation:
Rectangle WXYZ is dialated by a factor of 
to form the rectangle W'X'Y'Z'.
So, if the length of WX is 5 unit, the length of W'X' will be exactly given by,
lenght of WX 
Dialation factor
= 
unit
= 12 unit
Answer:
3ax-by+c
Step-by-step explanation:
Step1: Collect all the like terms
Like terms are similar variables, for example;
- (ax, 2ax) are all like terms since they have a common variable (ax)
- (by, -3by,by) are also like terms since they have a common variable (by)
- (c, c, -c) are also like terms since they have a common variable (c)
Step 2: Sum of all the groups of like terms
(ax+2ax)+(by-3by+by)+(c+c-c)=3ax-by+c
The answer is 3ax-by+c
