\left \{ {{x+y-9}} \right.

<h2></h2><h2>Explanation:</h2><h2 />

Let's take the point (2,-3) and use it to create a system of inequalities. In other words, this point will be a solution to our system.

First inequality:

x+y \ ? \ 2 \\ \\ We \ need \ to \ find \ the \ unknown \ symbol, \ so: \\ \\ Substituting \ values: \\ \\ (2)+(-3) \ ? \ 2 \\ \\ -1 \ ? \ 2 \\ \\ \\ Since \ -1 \ is \ less \ than \ 2 \ then \ our \ inequality \ becomes: \\ \\ x+y

Second inequality:

2x+3y \ ? \ -9 \\ \\ We \ need \ to \ find \ the \ unknown \ symbol, \ so: \\ \\ Substituting \ values: \\ \\ 2(2)+3(-3) \ ? \ -9 \\ \\ -5 \ ? \ -9 \\ \\ \\ Since \ -5 \ is \ greater \ than \ -9 \ then \ our \ inequality \ becomes: \\ \\ 2x+3y>-9

So our system is:

\left \{ {{x+y-9}} \right.

An expression is defined as a set of numbers, variables, and mathematical operations. The value of x for which the expression (x-1)(x-7)=0 is 1 and 7.

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

For the given expression, (x-1)(x-7), the value of x for which the expression will be equal to 0 can be found by equation the factors of the expression to 0. Therefore,

x-1 = 0

x = 1

and

x-7=0

x = 7

Hence, the value of x for which the expression (x-1)(x-7)=0 is 1 and 7.

I NEED HELP ASAPP!!!​
Llana [10]

Answer:

c

Step-by-step explanation:

x - 2y = -8 \\y = 5x-2

x - 2 y = - 8

add -x to both sides

x - 2y - x = -8 - x \\- 2y = -8 - x

multiply both sides by -1/2

-2y * (\frac{-1}{2} ) = (-8-x) (\frac{-1}{2} )

y = 4 + \frac{x}{2} \\y = \frac{x}{2} + 4

the equations don't have the same slope so they aren't parallel

The solpes product doesn't equal -1 so they aren't perpendicular
