Answer:
Step-by-step explanation:
x=1 y=3
Answer:
1050 ml ÷1000 = 1.05 liters of water
If you multiply 10 by 4 that gets you the area, but you need to find the surface so multiply the product by 7 and that gets you the surface which is 280
We have been given the function 
We know that the range is set of y values for which the function is defined. Therefore, we will find the value for x and then observe the restriction is y's values.

Now, we know that logarithm function is not defined for negative values. Hence, the value for y is always greater than zero.
Therefore, the range of the function is given by y>0
B is the correct option.
Think of this situation as a system of equations.
let y be the price of hotdogs
let x be the price of hamburgers
5y + 2x = 8
2y + 5x = 9.50
now use your solution method of choice
substitution, elimination, matrices, etc
