In your first attatchment, we want to plug in 21 for t and 3 for f. The function was modeled with the tables and flowers per bowl in mind, as t and f respectivly. Doing that gives us:
So she should have 390 flowers.
In the second attatchment, we want to plug in -2 for x, 1 for y and -2 for z. Even though they are letters, they represent some unknown value and in this case, their value is given, so:

Answer:
D
Step-by-step explanation:
When a function is being shifted to the left, all x values will be added by y units shifted. (The constant that comes with x is excluded, eg. 3x shifted by 2 units left, becomes 3(x+2) and not 3x+2.)
Likewise, when a function is being shifted to the right, all x values will be subtracted by y units shifted. (Constant rules applies as well.)
Given f(x) is shifted 3 units right,
the new function, g(x) becomes:
Therefore the answer is D in this case.
Answer:
It sold 43.57 iPhones for the same quarter in the previous year.
Step-by-step explanation:
It sold 61.0 million iPhone, which is an increase of 40% over the value of the previous year x.
This can be interpreted as:
61 million is 140% = 1.4 of the previous year amount, that is, x. So
It sold 43.57 iPhones for the same quarter in the previous year.
