Answer:
Let’s rewrite both expressions first
y=3/2x+3
-3x+2y=6
The first expression is already plotted on the graph, so we only need to work on the second one.
Let’s turn the second equation into slope-intercept form. We can later use this to graph.
-3x+2y=6
*add 3x on both sides*
-3x+2y=6
+3x +3x
__________
2y=3x+6
*divide each number by 2*
2y=3x+6
2y/2=3x/2+6/2
y=3/2x+3
Since this is the same equation as the one graphed, it means there are an infinite number of solutions. If one were to graph this, the points would be the same as the original.
Hope this helps comment below for more questions :)
Step-by-step explanation:
171 km/h
travel distance = 855 km
855 / 171 = 5 hours
it took him 5 hours to fly the 855 km (theoretically to the hospital).
normally, with a plane, you can't land on or at a hospital. you would need a helicopter to be able to do that.
so, he could only fly to a nearby airport, and then travel from there to the hospital. but we have no information about that.
Answer:
Step-by-step explanation:
Strictly speaking, 15% isn't precisely the same as 0.15; 0.15 is the decimal fraction used to calculate 15% of some quantity.
15% of 52 is indeed 7.8. $7.80 is the discount that is to be SUBTRACTED from the regular price ($52). Adding $7.80 to $52 is incorrect.
Also, 52 + 7.8 - 59.8 is incorrect: it's not an equation (but should be one), and we should be subtracting $7.80 from $52.
