Answer:
Interpreting as: (k)=0.
Step-by-step explanation:
For finding the answer of such a question, we only multiply the function by the given value. so as for f(x)=34x2−1, The function g(x), a vertical stretch of f(x) by a factor of 8 is g(x) =8(34x2−1)
5-2x=12
-2x=12-5
-2x=7 (multiplying by -1)
2x=-7
x= -7/2 = -3,5
Answer:
145°
Step-by-step explanation:
The angle is 90°+55°=145°
Average price of a CD/ mp3 player is : $ 150
Meanwhile , average price of an mp3 player is : $50
To buy 4 cd/mp3 player, we need $ 150 x 4 = $ 600
To but an mp3 player, we need $50 x 3 = $ 150
The total is $ 750
