Answer:

B. 2

Step-by-step explanation:

1) all the perpendicular lines are: y=x+C, where C - number;

2) in order to calculate C: to substitute (2;4) into the equation y=x+C:

4=2+C; ⇒ C=2;

3) finally, the required equation is: y=x+2.

The answer is B. 2.

Find the first five terms of the sequence described by the following recursive formula: an = an – 1 + an – 2 where a1 = 1.2 and
Sedaia [141]
The first if a twisted version of a Fibonacci sequence :P

If a1=1.2 and a2=2.3 and a(n)=a(n-1)+a(n-2)

a3=3.5, a4=5.8, a5=9.3

So the first five terms are:  1.2, 2.3, 3.5, 5.8, 9.3

The second is another modified Fibonacci sequence...

If a3=-5 and a4=3 then:

3=-5+a2, a2=8

-5=8+a1, a1=-13

a5=-5+3=-2

a6=-2+3=1

So the first six terms are -13, 8, -5, 3, -2, 1

Need help in math!!!
avanturin [10]

Answer:

(3,15)

Step-by-step explanation:

Rule 1

5x = y

Rule 2

x+12 = y

Set them equal

5x = x+12

Subtract x from each side

5x-x = x+12-x

4x= 12

Divide by 4

4x/4 = 12/4

x=3

5x=y

5*3 = y

15 = y

The solution is (3,15)
