Answer:

Option D.

Step-by-step explanation:

In a graph domain of the ordered pairs are represented by the x - coordinates and y-coordinates represent the Range.

The given set of ordered pairs is {(-2, -2), (0, 2), (2, 4), (3, -6)}

here x - coordinates of the ordered pairs are -2, 0, 2, 3.

Therefore, domain will be -2, 0, 2, 3.

Option D. is the answer.

Answer: 11, 30

Step-by-step explanation:

Given

There were a total of 41 national battlefields and national memorials

Suppose there are $x$ national battlefields

So, national memorials are $3x-3$

The sum of the two must be 41

$\Rightarrow x+3x-3=41\\\Rightarrow 4x=44\\\Rightarrow x=11$

So, there are 11 national battlefields and $3\times 11-3=30$ national memorials.

The total tax = $ 960

Total number of days =300

day =300

Seller credit =?

Formula:

$\bold{\text{Seller credit} = \frac{\text{total tax} \times \text{number of days}}{\text{day}}}$

$= \frac{960 \times 300}{360}\\\\= \frac{32 \times 300}{12}\\\\= 8 \times 100\\\\=800$

-7(n - 2) + 2n = -5(n + 6)

skad [1K]

Given the expression below

$-7(n-2)+2n=-5(n+6)$

To find n

Open the brackets

$\begin{gathered} -7(n-2)+2n=-5(n+6) \\ -7n+14+2n=-5n-30 \\ -7n+2n+14=-5n-30 \\ -5n+14=-5n-30 \end{gathered}$

Collect like terms

$\begin{gathered} -5n+14=-5n-30 \\ -5n-(-5n)=-30-14 \\ 0\ne-44 \end{gathered}$

Since, the sides are not equal,

Hence, there is no solution
