Achemist has a container of 12% peroxide solution and a container of 20% peroxide solution. she needs to mix the two solutions to create 100 ml of a 14% solution. if x represents the amount of 12% peroxide solution and y represents the amount of 20% peroxide solution she needs, which matrix equation can determine the amount of each solution she needs to make the 14% solution?

Step-by-step explanation:

We are given that,

The amount of 12% peroxide solution = x and the amount of 20% peroxide solution = y.

Since, the total amount of the solution to be made is 100 ml. So, the equation is

Also, the sum of the 12% solution and 20% of the solution is resulting in 14% solution. Then, the equation is

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
