Answer:
See the diagram.
Step-by-step explanation:
represents a circular disc with centre 
and radius 
First car is x
second car is y
25x+30y=1550
x+y=55
Multiply the second equation by -25 for elimination method to cancel out x
-25x-25y=-1375
Add the two equations
5y=175
y=35
Plug this value into the second equation
x+35=55
x=20
Final answers:
First car=20 gallons
Second car=35 gallons
Opposite angles formed by two intersecting lines are equal, so angle 1 is the same as angle 4. That means angle 1 = angle 5 as well.
<span>When a line intersects two parallel lines, the corresponding angles are equal. That is, if r and s are parallel, then the angles formed when l intersects r are the same s the angles formed when l intersects s. Angle 1 = Angle 5, Angle 2 = Angle 6, and so forth. Since we know angle 1 = angle 5, so from that you can see that r and s are parallel</span>
Answer:
Step-by-step explanation:
1) The domain is related to the behaviour of the x
the graph started when x is -11 and finish when x is 1
so
D : [-11 ; 1]
or -11 ≤x ≤ 1
the range is related to the behavior of y
the graph start when y is -7 and finish when y = 0
Range : [-7;0]
or -7≤ y ≤ 0
