Answer:
a. Rational; b. rational
Step-by-step explanation:
A rational number is the quotient of two integers.
a. ⁴/₇ + ⁻¹/₃
![\begin{array}{rcl}\dfrac{4}{7} + \dfrac{-1}{3} & = & \dfrac{12}{21} + \dfrac{-7}{21} \\\\& = & \dfrac{5}{21}\\\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Brcl%7D%5Cdfrac%7B4%7D%7B7%7D%20%2B%20%5Cdfrac%7B-1%7D%7B3%7D%20%26%20%3D%20%26%20%5Cdfrac%7B12%7D%7B21%7D%20%2B%20%5Cdfrac%7B-7%7D%7B21%7D%20%5C%5C%5C%5C%26%20%3D%20%26%20%5Cdfrac%7B5%7D%7B21%7D%5C%5C%5Cend%7Barray%7D)
The solution is rational.
b. √4 ⅖
![\begin{array}{rcl}\sqrt{4} \, \dfrac{2}{5} & = & 2 \, \dfrac{2}{5}\\\\& = & \dfrac{22}{5}\\\end{array}](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Brcl%7D%5Csqrt%7B4%7D%20%5C%2C%20%5Cdfrac%7B2%7D%7B5%7D%20%26%20%3D%20%26%202%20%5C%2C%20%5Cdfrac%7B2%7D%7B5%7D%5C%5C%5C%5C%26%20%3D%20%26%20%5Cdfrac%7B22%7D%7B5%7D%5C%5C%5Cend%7Barray%7D)
The solution is rational.
So the question is to estimate the value of g(1.95) and g(2.05). So by calculating i came up with a values of both the given and here are the following:
G(1.95) = -3.8 while the G(2.05) is 4.2.
I hope you are satisfied with my answer
At the start the temperature is -7 overnight it gets 12 degrees warmer so -7+12 =5 degrees than during the day it gets 12 degrees warmer so 5+12= 17 degrees
Try them and see.
For the first:
3(-3) + 0 = -9 . . . . not > -8
3(-2) + (-1) = -7 . . . is > -8 . . . . . 2) (-2, -1) is a solution
For the second:
4 - 4(-2) = 12 . . . . not ≤ -6
-2 -4(1) = -6 . . . . . is ≤ -6 . . . . . . 2. (1, -2) is a solution
