The steps are :
![x + 2y = 13 - - - (1)](https://tex.z-dn.net/?f=x%20%2B%202y%20%3D%2013%20-%20%20-%20%20-%20%281%29)
![- x + y = 5 - - - (2)](https://tex.z-dn.net/?f=%20-%20x%20%2B%20y%20%3D%205%20-%20%20-%20%20-%20%282%29)
![(1) + (2)](https://tex.z-dn.net/?f=%281%29%20%2B%20%282%29)
![x + 2y + ( - x) + y = 13 + 5](https://tex.z-dn.net/?f=x%20%2B%202y%20%2B%20%28%20-%20x%29%20%2B%20y%20%3D%2013%20%2B%205)
![3y = 18](https://tex.z-dn.net/?f=3y%20%3D%2018)
![y = 6](https://tex.z-dn.net/?f=y%20%3D%206)
![substitute \: y = 6 \: into \: (2)](https://tex.z-dn.net/?f=substitute%20%5C%3A%20y%20%3D%206%20%5C%3A%20into%20%5C%3A%20%282%29)
![(2)⇒](https://tex.z-dn.net/?f=%282%29%E2%87%92)
![- x + 6 = 5](https://tex.z-dn.net/?f=%20-%20x%20%2B%206%20%3D%205)
![- x = - 1](https://tex.z-dn.net/?f=%20-%20x%20%3D%20%20-%201)
![x = 1](https://tex.z-dn.net/?f=x%20%3D%201)
Therefore, you have to insert the values into the coordinates form so the answer willl be (1 , 6).
Answe
Given,
f(x) = 49 − x² from x = 1 to x = 7
n = 4
![\Delta x = \dfrac{7-1}{4}= 1.5](https://tex.z-dn.net/?f=%5CDelta%20x%20%3D%20%5Cdfrac%7B7-1%7D%7B4%7D%3D%201.5)
For x= 1
f(x₀) = 49 - 1^2 = 48
x = 2.5
f(x₁) = 42.75
x = 4
f(x₂) = 49 - 4^2 = 33
x = 5.5
f(x₃) = 49 - 5.5^2 = 18.75
x = 7
f(x₄) = 49 - 7^2 = 0
We have to evaluate the function on therigh hand point
![A = \Delta x [f(x_1)+f(x_2)+f(x_3)+f(x_4)]](https://tex.z-dn.net/?f=A%20%3D%20%5CDelta%20x%20%5Bf%28x_1%29%2Bf%28x_2%29%2Bf%28x_3%29%2Bf%28x_4%29%5D)
![A = 1.5 [42.75+33+18.75+0]](https://tex.z-dn.net/?f=A%20%3D%201.5%20%5B42.75%2B33%2B18.75%2B0%5D)
![A = 141.75](https://tex.z-dn.net/?f=A%20%3D%20141.75)
For Area for left hand sum
![A = \Delta x [f(x_0)+f(x_1)+f(x_2)+f(x_3)]](https://tex.z-dn.net/?f=A%20%3D%20%5CDelta%20x%20%5Bf%28x_0%29%2Bf%28x_1%29%2Bf%28x_2%29%2Bf%28x_3%29%5D)
![A = 1.5 [48+42.75+33+18.75]](https://tex.z-dn.net/?f=A%20%3D%201.5%20%5B48%2B42.75%2B33%2B18.75%5D)
![A =213.75](https://tex.z-dn.net/?f=A%20%3D213.75)
