According to the line of best fit and using ______, Sean can estimate that the balance of his loan will reach $0 in month _____.
First blank options:
1. Interpolation
2. Extrapolation
Second blank options:
1. 71
2. 69
3. 68
4. 59
Answer:
First blank: 2. Extrapolation
Second blank: 2. 69
Step-by-step explanation:
Extrapolation should be used because the point (x, y) is further than the points included in the table, that is, the x-coordinate will be greater than 12 when y = $0
Replacing y = 0 into the equation, we get:
0 = -115.9x + 8,007.30
115.9x = 8,007.30
x = 8,007.30/115.9
x = 69

3psquared+7p+2=0
Answer:
-1/3,-2
Step-by-step explanation:
The quadratic formula is [-b±√(b^2-4ac)]/2a. In this equations 3p^2 is a, 7p is b, and 2 is c.
Then just plug in the numbers.
[-7±√((-7^2)-4(3)(2)]/2(3)
[-7±√(25)]/6
(-7+5)/6 and (-7-5)/6
-1/3 and -2 are the answers, if you plug these numbers into the original equation, you find that they equal 0 which means that they work.
