Mathematics
1 answer:
kobusy [5.1K]3 years ago
4 0

Answer:

a = (x - b)/2

Step-by-step explanation:

2a + b = x

-b         -b

2a = x - b

/2        /2

a = (x - b)/2

for ex:

x = 3

b = 2

a = ((3) - (2))/2 = 0.5

a = 0.5

2a + b = x

2(0.5) + 2 = 3

Two angles are supplementary when they add up to 180 degrees 
m∠C = 180° - m∠B = 180° - 50° = 130°

What is the inverse of the function f(x) = 2x – 10?
Nadusha1986 [10]

Answer:

f⁻¹(x) = (1/2)x +5

Step-by-step explanation:

In y = f(x), swap the variables, then solve for y. The expression you get is f⁻¹(x).

... y = 2x -10

... x = 2y -10 . . . . . . swapped variables

... x +10 = 2y . . . . . add 10

... (1/2)x + 5 = y . . . . divide by 2

... f⁻¹(x) = (1/2)x + 5 . . . . . . rewrite using function notation
