Step-by-step explanation:
if you have for example x^2-4
just graf x^2 and that put down all point for 4
Answer:
The answer to this question is A
X=cost per hamburgurs
y=cost per hot dog
200x+150y=1450
200x+250y=1750
we can multiply first equation by -1 and add to 2nd
-200x-150y=-1450
<u>200x+250y=1750 +</u>
0x+100y=300
100y=300
divide both sides by 100
y=3
sub back
200x+150y=1450
200x+150(3)=1450
200x+450=1450
minus 450 both sides
200x=1000
divide both sides by 200
x=5
the cost of a hamburgur is $5
the cost of a hot dog is $3
"Adjacent" means next to each other. "Perpendicular" means at an angle of 90 degrees.
<span>Rectangles (this includes squares) have adjacent perpendicular sides. So do right triangles.</span>
