y = 1/2x + 3
change x and y
x = 1/2y + 3
now find the value of y and that is inverse function
x - 3 =1/2 y
y = 2x- 6
f-(x) = 2x - 6
<u />
for both domain : ( - ∞ , + ∞ )
range f (x) : ( - ∞ , + ∞ ) - { 0 }
range f-(x) :( -∞ , +∞)
Exterior angle equals sum of interior opposite angles
10x = 7x + 30
3x = 30
x = 10 so the exterior angle = 10 x 10 = 100 degrees
Answer:
x = 1/3
Step-by-step explanation:
$1,000 because 2.50x200=500 500+500=1,000
