Answer:
A)29 and B) 21,
Step-by-step explanation:
First,in the sequence
, the parameter 
must to be a integer.
Second, we need to solve the equations by .
All the option in the problem represent an 
Then, we need to prove all number in the options, if the result is a integer number, this option can be part of the sequence.
For A)
For B)
For C)
For D)
Only A) and B) only A and B meet the requirement
When solving system equations, we can use substitution method or elimination. Today I'm using substitution method.
First name the 2 equations.
3x + y = 3 (1)
x + y = 2 (2)
Now pick one equation and express one algebra in forms of the other.
From (2),
x = 2 - y (3)
Now substitute (3) into (1),
3(2-y) + y = 3
6 - 3y + y = 3
6 - 2y = 3
6 - 3 = 2y
y = 1.5
Now substitute y = 1.5 into (2)
x + 1. 5 = 2
x = 2 - 1.5
x = 0.5
Therefore the answer is x = 0.5 and y = 1.5

Christine has 2 MORE than Matt.
2 + 2 = 4(Christine)
4 + 2 = 6(total)
Answer: 4 x 16 = 64
16 + 44 = 60
I think..
Step-by-step explanation:
Answer:
The equation of the function: y = mx + b
- m = slope = (y₂ - y₁)/(x₂ - x₁) = [5 - (-3)]/(4 - 0) = (5 + 3)/4 = 8/4 = 2
- b = y-intercept = -3
Therefore, the equation is <u>f(x) = 2x - 3</u>
When x = 0, f(x) = 2(0) - 3 = <u>-3</u>
When x increases by 1, f(x) increases by <u>2</u> (slope = the rate of change)
