Answer:
b. (2, 5, 3)
Step-by-step explanation:
Trying the offered choices seems the fastest way to find the answer. The second choice works in all equations, hence is the solution.
Another strategy you can use is to see if the equations are dependent. Here, it looks like adding twice the third equation to the other two eliminates at least the x- and y-variables. If that eliminates z, then there are infinite solutions. Instead, it gives the equation ...
7z = 21
z = 3 . . . . . divide by 7
This answer is consistent with choice B, confirming that answer and eliminating the other choices.
The interval of the provided inequality expression is -5/9 to the infinity [(-5/9),∞) using the table of signs to solve the inequality.
<h3>What is the inequality equation?</h3>
Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.
The inequality given in the problem is,

Simplify the equation first by adding the same terms,

Now in this case, if the value x is ranges from -5/9 to infinity.
Thus, the interval of the provided inequality expression is -5/9 to the infinity [(-5/9),∞) using the table of signs to solve the inequality.

Well,
First solve the square root which is 7
Funny enough, this makes 7 * 7 = 49
So the answer is 49!
Hope I helped!
Answer:
(3,1) and (3,2)
Step-by-step explanation:
We are given that a relation
{(0,0.5),(0.5,1),(3,1),(1,6),(3,2)}
We have to find that ordered pair which causes this relation not to be a function.
We know that
Function: It is a mapping between two non- empty set A and B.
Every element of set A has unique image in set B.
One element of set A can not have two or more images in set B.
Two or more elements of set A have same images in set B.
In given relation images of 3 are 1 and 2 which is not possible if a relation is function because one element can not have two or more images.
The ordered pair (3,2) and (3,1) cause this relation not to be a function because image of 3 are 1 and 2 which is not possible .
Answer: (3,1) and (3,2)
i think it might be D i could be wrong
