Answer:
5
Step-by-step explanation:
First do substitution,
Which means |(4)-3|+4
Therefore 1+4=5
Answer:
Ques 1 - 
Ques 2 - 
Step-by-step explanation:
Ques 1: From the table, we see the relation,
5 = 2 × 2 + 1
9 = 2 × 4 + 1
13 = 2 × 6 + 1
17 = 2 × 8 + 1
21 = 2 × 10 + 1
That is, the relation from the table is given by,
, where x is the input and y is the output.
Hence, the required equation is
.
Ques 2: From the table, we see that,
2 = 12 × 0 + 2
14 = 12 × 1 + 2
26 = 12 × 2 + 2
38 = 12 × 3 + 2
50= 12 × 4 + 2
That is, the relation from the table is given by,
, where x is the input and y is the output.
Hence, the required equation is
.
P = $3,471.52, the principal
r = 3.1% = 0.031, annual ratr
n = 12, monthly compounding
t = 21 years
Note that n*t = 252.
The value after 21 years is
A = 3471.52*(1 + 0.031/12)²⁵²
= $6,650.91
The interest earned is
6650.91 - 3471.52 = 3179.39
Answer: $3,179.39
Answer:
x = -2
Step-by-step explanation:
![f(x) =x^2 -2x\:\: and \:\: g(x) = 6x + 4\\(f+g)(x) = f(x) + g(x) \\(f+g)(x) = x^2 -2x+ 6x + 4\\(f+g)(x) = x^2+4x + 4\\(f+g)(x) = (x+2)^2\\ 0 = (x+2)^2...[\because (f+g)(x) =0]\\0 = x+2\\\therefore x = -2](https://tex.z-dn.net/?f=f%28x%29%20%3Dx%5E2%20-2x%5C%3A%5C%3A%20and%20%5C%3A%5C%3A%20g%28x%29%20%3D%206x%20%2B%204%5C%5C%28f%2Bg%29%28x%29%20%3D%20f%28x%29%20%2B%20g%28x%29%20%5C%5C%28f%2Bg%29%28x%29%20%3D%20x%5E2%20-2x%2B%206x%20%2B%204%5C%5C%28f%2Bg%29%28x%29%20%3D%20x%5E2%2B4x%20%2B%204%5C%5C%28f%2Bg%29%28x%29%20%3D%20%28x%2B2%29%5E2%5C%5C%200%20%3D%20%28x%2B2%29%5E2...%5B%5Cbecause%20%28f%2Bg%29%28x%29%20%3D0%5D%5C%5C0%20%3D%20x%2B2%5C%5C%5Ctherefore%20x%20%3D%20-2)

you minus the the 7 and the 4 the 10th stay the same
