Answer:
<h3>C. t = x + x - 6</h3>
Step-by-step explanation:
Let the time use by other one technician be x
if the other technician takes 6 minutes less than the first technician, then the time taken by the other technician will (x - 6)
The total amount of time t it would take to run the tests if the technicians work together will be expressed by taking the sum of the time taken by the two technician as shown.
First technician = x
Second technician = x-6
Sum of the time taken
t = x+ (x-6)
Hence option C is correct
C) y=2x-1
How did i find this:
y=mx+b (slope-intercept form)
find your slope:
3-(-1)/2-0=4/2
Simplify: 2 <-- that's your slope (m)
Now to find your y-intercept:
y=2x+b
take one of the points (2,3) (0,-1) and substitute the y and x of the point into your equation:
-1=2(0)+b
solve and that gives you -1 as your y-intercept so c is correct
i know it's very confusing, but you got this!! i hope i helped

Hi!
Answer - Line R
Well refraction is the bending of something. I choose r because it may have refraction because of the 2 rectangles at the end of both sides.
Hope This Helps!
Answer:
The system will be:
x - y = 12
3x + 5y = 100
Step-by-step explanation:
Let The number of three-point questions ⇒ x
And the number of five-point questions ⇒ y
The giving a test has 12 more three-point questions than five-point questions.
So, x - y = 12
The test is worth 100 points.
So, 3x + 5y = 100
So. the system which represents this information is:
x - y = 12
3x + 5y = 100
And the solution of the system is x = 20 and y = 8
The number of three-point questions ⇒ x = 20 questions.
The number of five-point questions ⇒ y = 8 questions.
