Answer:
f(0) = 12
Step-by-step explanation:
You want to substitute 0 for x
f(0) = 5(0) + 12
f(0) = 12
Where did you get that A and B? I could answer if you were much more precise.
See this is what you should do ask
By comparing the dimensions above with the dimensions of Taylor's first rectangle, we have the following:
- No, a length of 6 in, width 3/4 in. is not proportional.
- Yes, a length of 1/2 in, width 4 in. is not proportional.
- No, a length of 1 1/8 in, width 9 in. is not proportional.
- No, a length of 3 in, width 5 5/8 in. is not proportional.
<h3>What is a direct proportion?</h3>
Mathematically, a direct proportion (direct variation) can be represented the following mathematical expression:
y = kx
Where:
- y and x are the variables or dimensions.
- k represents the constant of proportionality.
For the dimensions of the rectangular pieces of paper to be proportional, the length and width must remain in a constant ratio.
Next, we would determine the constant of proportionality (k) as follows:
k = y/x
k = (3/8)/3
k = 3/24
k = 1/8
For dimension 1, we have:
k = y/x
k = (6)/(3/4)
k = 24/3
k = 8 (No).
For dimension 2, we have:
k = y/x
k = (1/2)/4
k = 1/2 × 1/4
k = 1/8 (Yes).
For dimension 3, we have:
k = y/x
k = (1 1/8)/9
k = (9/8)/8
k = 9/8 × 1/8
k = 9/64 (No).
For dimension 4, we have:
k = y/x
k = (3)/(5 5/8)
k = 3/(45/8)
k = 3 × 8/45
k = 24/45 (No).
