D 35 units squared. If you would graph it on a piece of graph paper or look at the points one side would be the difference between 10 and 3 and the other side would be the difference between 7 and 2. Then taking those totals multiple them together to get the area
Answer:
a) The value of If(i)I = √2.
Step-by-step explanation:
Here the given function is f(x) = 1 - x
To Find: If(i)I
First;y, let us find the value of f(i).
Substituting x = i in f(x) , we get:
f(i) = 1- i
Now, The modulus value of a function P = A + B is written as :
![IPI = IA+BI = \sqrt{A^2 + B^2}](https://tex.z-dn.net/?f=IPI%20%3D%20IA%2BBI%20%3D%20%5Csqrt%7BA%5E2%20%2B%20B%5E2%7D)
So, here calculating the value of If(i)I :
![I1-iI = \sqrt{(1)^2 + (-1)^2} = \sqrt{1+ (1)} = \sqrt {1+1} = \sqrt{2}\\\implies I1-iI = \sqrt{2}](https://tex.z-dn.net/?f=I1-iI%20%20%20%3D%20%5Csqrt%7B%281%29%5E2%20%2B%20%28-1%29%5E2%7D%20%3D%20%5Csqrt%7B1%2B%20%281%29%7D%20%3D%20%5Csqrt%20%7B1%2B1%7D%20%3D%20%5Csqrt%7B2%7D%5C%5C%5Cimplies%20I1-iI%20%20%3D%20%5Csqrt%7B2%7D)
⇒ I1-1I = √2
or, If(i)I =√2
Hence, the value of If(i)I for f(x) = 1 -x is√2.

<u>ANSWER: </u>
The solution of the two equations 2x+3y=5 and 4x - y=17 is (4, -1).
<u>SOLUTION:
</u>
Given, two linear equations are 2x + 3y = 5 → (1) and 4x – y = 17 → (2).
Let us first solve the above equations using <em>elimination process.
</em>
For elimination, one of the coefficients of variables has to be same in order to cancel them.
Now solve (1) and (2)
eqn (1)
2 → 4x + 6y = 10
eqn (2) → 4x – y = 17
(-) ----------------------------
0x + 7y = -7
y = -1
Substitute y value in (2)
![4 x-(-1)=17 \rightarrow 4 x+1=17 \rightarrow 4 x=17-1 \rightarrow 4 x=16 \rightarrow x=4](https://tex.z-dn.net/?f=4%20x-%28-1%29%3D17%20%5Crightarrow%204%20x%2B1%3D17%20%5Crightarrow%204%20x%3D17-1%20%5Crightarrow%204%20x%3D16%20%5Crightarrow%20x%3D4)
So, solution of two equations is (4, -1).
<u><em>Now let us solve using substitution process.</em></u>
Then, (2) → 4x – y = 17 → 4x = 17 + y → y = 4x – 17
Now substitute y value in (1) → 2x + 3(4x – 17) = 5 → 2x + 12x – 51 = 5 → 14x = 5 + 51 → 14x = 56
x = 4
Substitute x value in (2) → y = 4(4) – 17 → y = 16 – 17 → y = -1
Hence, the solution of the two equations is (4, -1).
