I'd say
Put one end of the compass on point P and the other end on point Q.
This way, you can construct (part of) a circumference with radius PQ with center P.
If you connect point P with any point on the circumference, this segment will be another radius of the circumference, and thus congruent to PQ.
1. Make an equation.
Moving company #1: y = 17x + 840
Moving company #2: y = 22x + 760
2. Put the equations together and solve
17x + 840 = 22x + 760
-17x -17x
840 = 5x + 760
-760 -760
80 = 5x
5 5
16 = x
When a job is 16 hours they both charge the same thing.
2 and 3 are correct. 1 is false because the graph opens downward. If the a value, which is -1 in this case, is less than 0, the graph will open downward. -1 is less than 0 so the graph opens downward
Well you do, -14 times 28
witch ='s 392
then add the negative sign back
and bam -392= -14(28)
8 : 10 Can also be written as
4 : 5 ( dividing by 2) or
16 : 20 (multiplying by 2)
ideally by multiplying both sides by any number we get equivalent ratios
