Answer:
Subtract 2x from each side, Subtraction Property
Step-by-step explanation:
Answer: Function 1
Step-by-step explanation:
Function 1 has rate of change of
(15.75 - 14.25)/(1 -(-1)) = 0.75. This was calculated using slope formula.
Function 2 has rate of change of 5/6, which is 0.833.
Answer: 40.9
Step-by-step explanation:
Given
angle given is ![23^{\circ}](https://tex.z-dn.net/?f=23%5E%7B%5Ccirc%7D)
![RC=16](https://tex.z-dn.net/?f=RC%3D16)
Using trigonometry
![\Rightarrow \sin 23^{\circ}=\dfrac{RC}{PC}\\\\\Rightarrow \sin 23^{\circ}=\dfrac{16}{X}\\\\\Rightarrow X=\dfrac{16}{\sin 23^{\circ}}\\\\\Rightarrow X=40.948\approx 40.9](https://tex.z-dn.net/?f=%5CRightarrow%20%5Csin%2023%5E%7B%5Ccirc%7D%3D%5Cdfrac%7BRC%7D%7BPC%7D%5C%5C%5C%5C%5CRightarrow%20%5Csin%2023%5E%7B%5Ccirc%7D%3D%5Cdfrac%7B16%7D%7BX%7D%5C%5C%5C%5C%5CRightarrow%20X%3D%5Cdfrac%7B16%7D%7B%5Csin%2023%5E%7B%5Ccirc%7D%7D%5C%5C%5C%5C%5CRightarrow%20X%3D40.948%5Capprox%2040.9)
Using cosine formula
![\Rightarrow \cos 23^{\circ}=\dfrac{PR}{X}\\\\\Rightarrow PR=40.9\times \cos 23^{\circ}\\\Rightarrow PR=37.69\approx 37.7](https://tex.z-dn.net/?f=%5CRightarrow%20%5Ccos%2023%5E%7B%5Ccirc%7D%3D%5Cdfrac%7BPR%7D%7BX%7D%5C%5C%5C%5C%5CRightarrow%20PR%3D40.9%5Ctimes%20%5Ccos%2023%5E%7B%5Ccirc%7D%5C%5C%5CRightarrow%20PR%3D37.69%5Capprox%2037.7)
