Answer:
16 nickels
Step-by-step explanation:
I just divided 32 by 2 I don't know if its completely right though
2n + 20 = -2
20 + 2 = -2n
22 = -2n
22/2 = n
11 = n
Answer:
18
Step-by-step explanation:
1/2bh
9 x 4 = 36
36/2 = 18
area = 18
Using linear function concepts, it is found that the true statements are as follows:
- The number of biology degrees increases by about 2.414 each year after 2000.
- About 73.000 students graduated with degrees in psychology in 2000.
- In 2000, more students graduated with psychology degrees than biology degrees.
<h3>What is a linear function?</h3>
A linear function is modeled by:

In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value.
In this problem, for psychology, the model for the number of graduated students in t years after 2000 is:
P(t) = 2,376t + 73,219.
For biology, it is given by:
B(t) = 2,414t + 56, 545
Hence, the correct statements are:
- The number of biology degrees increases by about 2.414 each year after 2000.
- About 73.000 students graduated with degrees in psychology in 2000.
- In 2000, more students graduated with psychology degrees than biology degrees.
