Answer:

(2,-2)

Step-by-step explanation:

To be a solution to the system of inequalities, it must be in the double shaded region.

(-2,2) is not shaded at all

(4,3)  is shaded with the dots.

(2,-2)  had dots and grey.

(-4,0) is shaded with grey

The only double shaded region is (2,-2)

Answer: C


Step-by-step explanation: C is the correct answer because the ordered pair (2,-2) is in the space where the systems can have the same answer. You can also tell because (2,-2) is in the area where the solid and the dotted space intersect.

Rewrite exponential expressions
Dahasolnce [82]

Answer:

A = 48

Step-by-step explanation:

In this equation, we can factor out the expression (\frac{1}{7} )^x. If we do so, the expression becomes:

(\frac{1}{7})^x((\frac{1}{7})^{-2} - 1)

We can simplify to get:

(\frac{1}{7} )^x(49 - 1)

and get:

48*(\frac{1}{7})^x

Therefore, A = 48

Let U={x: x is an integer and 2≤x≤10}. In each of the following cases, find A,B and determine whether A⊆B,B⊆A, both or neither:
12345 [234]

A is not a subset of B but B is a subset of A (that is can be found in A) that is B⊆A is correct

<h3>Set theory</h3>

Set is defined as the arrangement of elements. They can be represented using the venn diagram.

Given the following sets

U = {x: x is an integer and 2≤x≤10} = {3, 4, 5, 6, 7, 8, 9}
A = {x: 2x+1>7} = {x > 3}

B={x: x^2>20} = {x >± 20}

From the set, can see that A is not a subset of B but B is a subset of A (that is can be found in A) that is B⊆A is correct
