Answer:
x=125
Step-by-step explanation:
To solve we must find a number that when divided by 5 equals 25.
To do this we can either...
Take each answer choice and plug in the value into the x spot and see if it works...
5/5=25 WRONG
10/5=25 WRONG
25/5=25 WRONG
125/5=25 CORRECT!
ORRR... we can set the equation so that the x is alone on one side.
To do this we can multiply both sides by 5
=25 ---> x=25×5
x=125
Answer:
Option: D is the correct answer.
D) –2x + y ≥ 4
x + y < 2
Step-by-step explanation:
We are asked to find the linear inequality that represents the following graph.
Clearly from the graph we could observe that one line is dotted and the other is solid line.
i.e. one inequality is strict while the other is a inequality with equality sign.
<u>Dashed line:</u>
It passes through (0,2) and (2,0).
Hence, the equation of line is:
As the shaded region is towards the origin.
Hence, the inequality will be:
x+y<2.
<u>Solid line:</u>
The line passes through (-2,0) and (0,4).
hence equation of line is:
i.e
Now, as the shaded region is away from the origin hence the inequality which will be used is:
Hence, option: D is the correct answer.
D. –2x + y ≥ 4
x + y < 2
