-10x+8 and 5x-4 is a possible combination. Those are both linear equations when added together will give you -5x+4
I'm guessing you are using military time.
Note, 23:00 is the same as 11:00 pm, and 12:20 is the same as 12:20 pm
Also note: 1 hour = 60 minutes
1) Change 1 hour inside 23:00 to minutes
23:00 = 22:60
Subtract
22:60 - 12:20 = 10:40
The time between 12:20 and 23:00 is 10 hours and 40 minutes
hope this helps
Answer:
Linear: y = x, y = x/2 - 3, 3x + 2 = 12
Nonlinear: y = 6/x - 2, y = 3x^3 + 5
Step-by-step explanation:
Linear functions form straight lines while nonlinear functions do not.
Y = -1/3x + 2.....the slope here is -1/3. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, flip the slope and change the sign. So the slope is -1/3.....flip it and it becomes - 3/1....change the sign and it becomes 3/1 or just 3. So ur perpendicular line will have a slope of 3.
y = mx + b
slope(m) = 3
(-3,-5)....x = -3 and y = -5
now sub into the formula and find b, the y int
-5 = 3(-3) + b
-5 = -9 + b
-5 + 9 = b
4 = b
so ur perpendicular equation is : y = 3x + 4 <===
Answer:
x=5/2
Step-by-step explanation:
Calculate, rewrite, remove the paretheses
Collect the like terms
Swap sides 75=30x swap to 30x=75
Then divide both sides
