Answer:
f^-1(x) = (x +5)/3
also = 1/3 x + 5/3
Step-by-step explanation:
Just to be clear, the ^-1 has nothing to do with negative exponents. It just unfortunately looks the same as a negative exponent.
Anyway, there's three basic steps. First write y instead of f(x). Then switch the x and y. Then solve for y.
f(x) = 3x - 5
write y in place of f(x).
y = 3x - 5
SWITCH x and y.
x = 3y - 5
SOLVE for y.
-3y + x = -5
-3y = -x - 5
y = (-x - 5)/-3
y = (x + 5)/3
OR
y = (1/3)x + 5/3
f^-1(x) = 1/3 x + 5/3
14 is the answerrrrrrrrrrrrr
The value of the exterior angle is the sum of the angles opposite. This is an equilateral triangle, so all angles are equal to 60 degrees.
60 + 60 = 120
So angle DAB is 120 degrees.
32/4 would be the correct answer i presume because 8*4 = 32 32/4 because we said 4 was the denominator so
32/4
