Answer:
4 is the range of the function
Answer: x = -1 and y = 9
The two equations are:
-9x + 2y = 23
-4x -y = -3
Now find for x in the first equation...
-9x + 2y = 23
-9x = 23 - 2y
x = (23 - 2y)/-9
Now place this value of x in the second equation and find for y...
-4{(23-2y)/-9} - y = -3
-92 + 8y + 9y = -3 * -9
17y = 27 + 92
y = 119/17
y = 7
Now place the value of y in the first equation," -9x + 2y = 23 " and find x
-9x + 2*7 = 23
-9x + 14 = 23
-9x = 23-14
x = 9/-9
x = -1
There you go! Hope it helps

Answer:
1. 4.5 g
2. 56.25 g
Step-by-step explanation:
3 % substance solution means :
3 g of dry substance is present in 100 g of solution.
By unitary method:
The weight of dry substance in 1 g of solution = 
The weight of dry substance in 150 g of solution = 
Let the weight of solution be w.
8 % solution contains 8 g dry substance in 100 g.
We have to find the weight of the solution(w) which contains 4.5 g of dry substance.
