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>
What this is asking is for you to plug values into the following function:
Since the question is asking you to find
, this is how you work it out:
You take the function;
And plug the numbers indicated in for x;
So the answer to f(3) - f(1) =
Answer:
y = 1/2x - 2.5
Step-by-step explanation:
(15, 5) and (42, 18.5)
Slope:
m=(y2-y1)/(x2-x1)
m=(18.5 - 5)/(42 - 15)
m = (13.5)/27
m = 1/2
y - y1 = m(x - x1)
y - 5 = 1/2(x - 15)
y - 5 = 1/2x - 7.5
y = 1/2x - 2.5
Cramer's Rule is a method that uses determinants to solve systems of equations that have the same number of equations as variables
