To find the discount, multiply 60 by .2, which is 12. Now subtract 12 from 60. The trousers should cost $48 now because the cost has been reduced by 20% of 60, which is $12.
Answer:
11x + 12
Step-by-step explanation:
9x + 3x = 11x
8 + 4 = 12
Points Lying on the undefined curve are
x : 0 1 2 3 4
f(x): 3 7 29 87 199
Plotting the points on the coordinate plane
As you will see, the value of x increases , value of y increases .
It is not linear, because slope between two points is not same.
Neither quadratic nor cubic , it is not cutting x axis .
So, As value of x increases, value of y does not increases by a fixed quantity, but it increases.
So, option (D) Exponential ,Function word is the right word Describing these points.
(i) The scale factor is 6 because of the ratio between the 2 given corresponding sides.
I don't know the second part, but I hope this helps regardless.
