Y=mx+b
3= -1/2(6) + b
3= -3+b
3+3= b
b= 6
y= mx+b
2= -1/2x+ 6
2-6 = -1/2x
-4 = -1/2x
-4•-2 = -1/2x •-2
x = 8
(8,2)
You didn't attach anything, but this is how you should solve this equation: given an equation the solutions are
In your case, the values are . If you plug these values inside the solving formula, you have
So, the two solutions are 1 and 7
Answer:
-11
Step-by-step explanation:
The number and sign after x is always the y-intercept
Let the cost of each drink is $x and the cost of each hot dog is $y.
According to the given data, 3 drinks and 2 hot dogs cost $4.80. In equation form, we can write it as:
1 drink and 1 hot dog costs $2.00. In equation form, we can write it as:
Using this value of x in first equation, we get:
Thus the cost of one hot dog is $1.20
