Answer:
The answer is A.
Step-by-step explanation:
Lets call f(x)=y, so y= 4*(3*x-5), we want to find 'x', using 'y' as a the variable.
Now lets change the name of 'y' to 'x', and 'x' to f^-1(x).
f-1(x) = (x+20)/12
Answer:
c
Step-by-step explanation:
find 6%
429.99*6/100= 25.7994
Total cause of the laptop
429.99+25.7994= 455.79
-2,-7 because you go the same ammount in the opposite direction
Length is 95 yards.
The perimeter of a rectangle is the sum of four sides. The four sides are either its length or width.
A rectangle has four sides where its angles are all right angles and its opposite sides are congruent or of equal size.
Perimeter = 2length + 2width ==> P = 2L + 2W
354 = 2L + 2(82)
354 = 2L + 164
to get the length. we must transfer all like signs.
2L = 354 - 164
2L = 190
2L / 2 = 190 / 2
L = 95 yards.
Steps to solve for the zero:
(x + 7)(x + 5) = 0
~Set both factors to equal zero
x + 7 = 0
x + 5 = 0
~Solve for x in [ x + 7 = 0 ]
x + 7 = 0
x + 7 - 7 = 0 - 7
x = -7
~Solve for x in [ x + 5 = 0 ]
x + 5 = 0
x + 5 - 5 = 0 - 5
x = -5
Therefore, the solutions are x = -7 and x = -5
Best of Luck!
