Verify if 1/2x-2 and g(x) = 2x + 4 are inverses

Mathematics
1 answer:
Triss [41]3 years ago
5 0
They are inverses if f( (g(x)) = x

f((g(x)) =  (1/2) (2x + 4) - 2  = x + 2 - 2 = x

so this proves that g(x) is the inverse of f(x)

the other inverse g((f(x))  should also be = x

A is the point with coordinates (4 6)
Delicious77 [7]

Answer:

d = 6

Step-by-step explanation:

Given the coordinates A(4, 6) and B(d, 12) with the gradient of AB to be 3

Gradient m = y2-y1/x2-x1

Substitute the given values

3 = 12-6/d-4

3 = 6/d-4

Cross multiply

3(d-4) = 6

Expand

3d - 3(4) = 6

3d - 12 = 6

Add 12 to both sides

3d - 12 + 12 = 6 + 12

3d = 18

Divide both sides by 3

3d/3 = 18/3

d = 6

Hence the value of d  is 6

Three erasers and five pencils cost $7.55. 6 erasers and 12 pencils cost $17.40. How much does 1 eraser cost? How much does 1 pe
Sphinxa [80]

Answer:

Step-by-step explanation:

erasers=e  

pencils=p

3e+5p=7.55   ...(1)

6e+12p=17.40

divide by 2

3e+6p=8.70  ...(2)

(2)-(1) gives

p=8.70-7.55=1.15

from (1)

3e+5(1.15)=7.55

3e+5.75=7.55

3e=7.55-5.75

3e=1.80

e=1.80/3=0.60

cost of 1 eraser=$0.60

cost of 1 pencil =$1.15
