Answer:
x = $1.5, y = $2.75
Step-by-step explanation:
5x + 6y = 24
3x + 2y = 10
Solve for y
2y = 10 - 3x
y = 5 - 3/2x
Plug y into first equation
5x + 6y = 24
5x + 30 - 9x = 24
-4x = -6
x = $1.5
y = $2.75

-2x+5y=-10 can be rewritten as
y=2/5x-2
therefore the y intercept is (0,-2) because in the equation y=mx+b, b is the y intercept and -2= b in this equation.
Answer:
The cost of one hot dog can't be determine from the given condition
Step-by-step explanation:
From the question,
Total cost of four hot dogs and three bags of candy is $14.37 and twelve hot dogs and nine bags of candy is $24.74.
So,
Let the number of hot dog be x
and the number of bags of candy be y.
According to question,
Equations formed by given statement are,
.................(1)
.................(2)
Here, these are the linear equation in two variables says x & y.
When ,
≠ = gives Unique solution.
= = gives Infinite many solutions.
= ≠ gives No solution.
From Equation (1) & (2) we get ,
= ≠
This condition says that the given equation have no solution.
Hence the cost of one hot dog can't be determine from the given condition.
