We have the following function:
 y = ax + b
 We evaluate two points in the function:
 For (0, 2)
 2 = a (0) + b
 b = 2
 For (1, 4)
 4 = a (1) + b
 4 = a + 2
 a = 4-2
 a = 2
 Then, we have:
 a + b = 2 + 2 = 4
 Answer:
 
The result of a + b equals 4

Factorization of:
zubka84 [21]

Answer:

Step-by-step explanation:

2800: 2 * 2 * 2 * 2 * 5 * 5 * 7

75: 3 * 5 * 5

168: 2 * 2* 2 * 3 * 7

It's not really multiplication. It's more division.

Try 2800 as a sample. What you are trying to do is break this down into primes. The first prime is 2

2800/2 = 1400

1400 / 2 = 700

700 / 2 = 350

350 / 2 = 175. That's the end of what the 2s can do.

175 / 5 = 35

35/ 5 = 7 7 is a prime. You are done. Now run up the ladder.

2800: 2 * 2 * 2 * 2 * 5 * 5 * 7

75 is not an even number. It has no 2s. Go to 3

75 / 3 = 25.

25 / 5 = 5

That's the end

75: 3 * 5 * 5

Your calculator can be of great help. The rule is keep factoring until you get a decimal remainder. Move on to the next prime. Stop when the last division gives you a prime.

Can anyone help me with inverse function please? ​
12345 [234]

{h}^{ - 1} oh(x) = x \\  {h}^{ - 1} (4x + m) = x \\ 2k(4x + m) +  \frac{5}{8}  = x \\ 8kx + 2km +  \frac{5}{8}  = x

k and m must satisfy 8k = 1 mean k = ⅛

and 2km+⅝=0 mean m = -5/2
