Answer: Monitors A and B
Step-by-step explanation:
The similar monitors based on display resolution are those with similar ratios.
Take the ratios to their simplest forms to see which are similar.
Monitor A
= 640 : 480
= 16 : 12
= 4 : 3
Monitor B
= 800 : 600
= 8 : 6
= 4 : 3
Monitor C
= 1,280 : 800
= 32 : 20
= 8 : 5
<em>Monitors A and B are similar as they have the same display ratio. </em>
Step-by-step explanation:
difference of 9 and 2 is 9-2
product of 4 and (9-2)
4*(9-2)
h = 2

You must isolate the variable to solve using the order of operations, or PEMDAS.

Subtract 3 from both sides of the equation, and subtract 2h from both sides of the equation.

Divide both sides of the equation by 2.

Answer:
D
Step-by-step explanation:
The other graphs are functions.
Graph A is a linear function, and C is an Absolute Value Function.
Graph B also seems to be a function.
However- I can only narrow it down to B or C. I apologize if my answer is not correct.
