<h3>Answer:   C (-9, 8)</h3>

============================================================

Explanation:

The point (9,8) is in the original set of ordered pairs.

We cannot include (9,-8) since x = 9 is already listed. We can't have repeated x values. If x repeats, then we don't have a function.

This rules out choice A.

Choices B and D are eliminated for similar reasoning.

Choice C can be included because x = -9 hasn't been mentioned yet.

Note: A function is when any given x value leads to exactly one y value.

Find the area of the shaded region. Round your answer to the nearest tenth if needed.
user100 [1]

Answer:

140 inches

Step-by-step explanation:

Find the area of the square.

4 + 10 = 14 (Length)

11 + 4 = 15 (Breadth/Width)

Area = 14 x 15 = 210 inches

Find the area of the 2 unshaded squares in the square.

Area of square at the top = 4 x 4 = 16 inches

Area of square at the bottom = 6 x 9 = 54 inches

Add the 2 squares of the area together.

16 + 54 = 70 inches

Now deduct the area of the huge box by the area of the 2 unshaded squares.

210 - 70 = 140 inches

HOW TO FINISH IT? Complete the table and pattern. Determine the common difference. Write the explicit rule.
sp2606 [1]

a_{n} = a_{1} + d(n - 1)   <em> a₁ is the first term, d is the difference, and n is the term</em>

a₁ = -5

d = -5

a_{n} = -5 - 5(n - 1)

a_{n} = -5 - 5n + 5  

a_{n} = -5n            <em>explicit formula</em>

a_{n} = -5a_{n-1}       <em>recursive formula</em>

Which graph shows the solution to the following system of inequalities x+y&gt;4 x+y &lt;3
LekaFEV [45]

Answer:

The following graph has no solution.

Step-by-step explanation:

Since , we are given a system of inequalities as:

             x+y>4

and        x+y<3

So from the two in equalities we could clearly see that in one the sum of x+y>4 while in the other the sun x+y<3 which is not possible.

This could also be seen from the graph.

The graph will not have any common region and are parallel lines.

Hence, the graph has no solution.
