Answer:

Option B. 4m - 24n + 3

Step-by-step explanation:

There are two polynomials (17m - 12n - 1) and (4 - 13m - 12n)

We have to add the given tow polynomials

(17m - 12n -1) + (4 - 13m -12n)

Now we will put the similar terms together and add them.

(17m - 12n -1 + 4 - 13m - 12n) = 17m - 13m -12n - 12n -1 + 4 = 4m - 24n + 3

The final answer by adding them is Option B. 4m - 24n + 3

17m-12n-1+ 4-13m-12n
Add like terms-- (17m-13m= 4m) (-12n-12n= -24n )(4-1=3)
Then put them together to get your answer.
So the answer is 4m -24n+3

Which of the following relations is a function? A. (1, 4), (-4, 2), (8, 1), (-8, 2) B. (1, 4), (-4, 6), (1, 3), (-8, 2) C. (1, 0

Len [333]

Answer:

A. (1, 4), (-4, 2), (8, 1), (-8, 2)

Step-by-step explanation:

Each x goes to only 1 y to be a function

A. (1, 4), (-4, 2), (8, 1), (-8, 2)

function

B. (1, 4), (-4, 6), (1, 3), (-8, 2)

1 goes to 4 and 3 so not a function

C. (1, 0), (-4, 3), (8, 1), (-4, 5)

-4 goes to 3 and 5 so not a function

D. (8, 1), (-4, 4), (1, 1), (8, 2)

8 goes to 1 and 2 so not a function

4n=1/2(2n-12) check the solution to the example problem by replacing n in the original equation with -2 and evaluating both side

worty [1.4K]

Answer:

The true statement is that the expression is satisfied for n = -2.

Step-by-step explanation:

Given:

$4n = \frac{1}{2}\times (2n-12)$

To check:

Left hand side = Right-hand side ( for n = -2)

Proof :

For n = -2

Consider Left hand side of the equation given above.

∴ Left hand side = 4n

= 4×(-2) ......................for n = -2

= -8

Consider Right-hand side of the equation given above

∴ Right-hand side = $\frac{1}{2}\times (2n-12)$

$=\frac{1}{2}\times (2\times(-2) - 12) \\= \frac{1}{2}\times (-4 - 12)\\ =\frac{1}{2}\times (-16)\\ =-8$

Now we get Left hand side equal to Right hand side

i.e. Left hand side = Right hand side

i.e. $4n = \frac{1}{2}\times (2n-12)$ is true for n = -2

Find the nth term -1 8 19 32 47

koban [17]

$\bold{\text{Answer:}\quad \text{Recursive formula:}\ a_n=a_{-1}+2n+5}\\.\qquad \qquad \ \text{Explicit formula:}\ a_n=2n^2+3n-6$

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

-1 → 8 = +9

8 → 19 = +11

19 → 32 = +13

32 → 47 = + 15

a₁ = -1

d = 2n + 5

Recursive formula is: the previous term plus the difference (d)

$\large\boxed{a_n=a_{n-1}+2n+5}$

Explicit formula is the first term plus the product of d and n-1:

$a_n=a_1+d(n-1)\\a_n=-1+(2n+5)(n-1)\\a_n=-1+2n^2-2n+5n-5\\\large\boxed{a_n=2n^2+3n-6}$
