Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
3x - 6y = - 12 → (1)
x - 2y = 10 → (2)
Rearrange (2) expressing x in terms of y by adding 2y to both sides
x = 10 + 2y
Substitute x = 10 + 2y into (1)
3(10 + 2y) - 6y = - 12 ← distribute left side
30 + 6y - 6y = - 12 ( subtract 30 from both sides )
0 + 6y - 6y = - 12 - 30 , that is
0 = - 42 ← not possible
This indicates that the system of equations has no solution.
The 2 lines must therefore be parallel with no intersection
Answer:
7 Hours and 15 Minutes
Step-by-step explanation:
I converted the times into 24-hour format, then converted the minutes into decimal form, then subtracted.
14.75 - 7.5 = 7.25 or 7 Hours and 15 Minutes
I hope this helps you sorry to get it wrong
Answer: 16.8 meters
Step-by-step explanation:
32 meter - 120 centimeters = 30.8 meters
30.8 meters - 14 meters = 16.8 meters.
Answer:
hi! so we have 2 points right? you will need to use something called the slope formula y2-y1/x2-x1 we're subtracting our y values of both points and x values of both points while dividing them this gives us a slope of a line
now I want you to label before you do this in your head! it can get confusing to think about it so label label (x1-1,y1 4) (x2 14,y2 -2) now you have them labeled this parts easy! use the formula -2-4/14--1 okay now use your calculator you get -2/5 and now you have your m or slope!
memorize y2-y1/x2-x1 now! it will save you!
