A chemist needs 170 ml of a 71% solution, but only has 59% and 93% solutions available. find how many ml of each that dhould be mixed to get the desired solution

110 ml of 59% solution is mixed with 60 ml oh 93# solution to get the desired solution.

Step-by-step explanation:

We are given the following in the question:

170 ml of 71 solution is to be made.

Let x be the amount of 59% solution used and y be the amount of 93% solution used.

Total volume = 170 ml

Thus, we can write the equation,

Desired solution  = 71%

Thus, we can write the equation:

Solving the two equations, we get,

Thus, 110 ml of 59% solution is mixed with 60 ml oh 93# solution to get the desired solution.

answer

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.
