Answer:
<u><em>domain</em></u> is your <u><em>x value</em></u>, and <u><em>range</em></u> is your <u><em>y value.</em></u>
Step-by-step explanation:
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
Answer:
1 --> E
2 --> C
3 --> B
4 --> A
5 --> D

Step-by-step explanation:
Any line y = a
<span>y = x, for x = -x, y = -x => y = -y </span>
<span>y = 2x, for x = -x, y = -2x => y = -y</span>
