Answer:
y=-5x+-3
Step-by-step explanation:
the slope is negative and its rise over run so 5/1 which is five and the y intercept is -3
2 3/4 / 1/3 = 11/4 / 1/3 = 11/4 * 3 = 33/4
= 8 1/4 miles per hour
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
2+2=4
4+2=6
