This is not a multiple choice question: Part 2:
a. What formula will be used to relate the data? Explain the part of the formula.
b. Practice using the formula.
c. Relate the given data to the formula and explain. Write a "Let" statement.
d. State and explain the equation that would solve the given problem.

2. In 2010, the number of students who received online math tutoring at the math hotline was 110. In 2015, that number has risen to 345. Find a linear model to fit the data and use it to predict the number of students who received online tutoring from the math hotline in 2019.

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

the equation is not included but the answer is (1.50, 2.00, 2.75)

step-by-step explanation:

no

explanation:

you can be freinds, and people but not follow people.

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
