Answer:

C. Both (1,11) and (-1,-5)

Step-by-step explanation:

Ok so,

let's try to plug in the first ordered pair into the equation. It should look like this:

11 = 8+3

11=11 CORRECT

now let's try to plug in the second ordered pair. it should look like this:

-5 = -8+3

-5 = -5 CORRECT

hope this helps. have a good day!!

Consider this sequence

pochemuha

Hello,

$u_{1} =1*(8-7)=1*(2*4-(6+1))\\
 u_{2} =2*(10-7)=2*(2*5-(6+2))=2*(2*(4+1)-(6+2))\\
 u_{3} =3*(12-9)=3*(2*6-(6+3))=3*(2*(4+2)-(6+3))\\
 u_{4} =4*(14-10)=4*(2*7-(6+4))=4*(2*(4+3)-(6+4))\\

$

$u_{10}=10*(2*(4+10)-(6+10))\\
=10*(28-16)
$

$...\\\\
u_{n} =n*(2*(n+n-1)-(6+n))\\
=n*(4n-2-6-n)=n(3n-8)\\

Answer:

Step-by-step explanation:

________

Good evening ,

_______________

-4x+3y=-12

-2x+3y=-18

This system is the same as

y = (4/3)x - 4

y = (2/3)x - 6

We note that the two coefficients 4/3 and 2/3 are positives

So the right answer is C (graph 2).

Use Pascal’s Triangle to determine the second term of the expansion of (x + 2)^4.

denis23 [38]

Answer: 10x³

<u>Step-by-step explanation:</u>

n=0 1

n=1 1 2 1

n=2 1 3 3 1

n=3 1 4 6 4 1

n=4 1 5 10 10 5 1

The second term of the expansion is: 5(a)³(b)

= 5(x)³(2)

= 10x³
