Answer:
1/2
Step-by-step explanation:
since 10petrols=1 oil
therefore 5petrols=1/2
The y-coordinates are the same, so the length of this horizontal line segment is the difference between the x-coordinates.
Length = 7 - (-5) = 12 units
- for line B so the set of equations to have no solutions bc. x+y=2 and so y=2-x
so from x+y=4 will result y=4-x
so this is the right equation for line B so the set of equations has no solutions
Full turn = 360°
Number of 90° = 360 ÷ 90 = 4

Answer:
you could use the formula
Step-by-step explanation:
That is x = -b<u>+</u>√b^2 - 4ac/2a
where ur x is
x= -b+√b^2-4ac/2a or
x= -b-√b^2-4ac/2a
