Hello! Hmm. Let’s see. I think it has to be 100x + 60y <= 600. The x variable represents the fast machine suits and the y variable represents the slow machine wet suits. You wrote the greater than or equal to sign, which is not correct. The maximum means no more than, which would mean the less than or equal to sign. The sign you wrote would mean at least that amount or more.
We are asked to determine the value of a such that the function f(x) = ax^2 + 5 is fit for the point given (-1,2). In this case, we substitute 2 to y and -1 to x. The result is then 2 = a*(-1)^2 + 5 ; 2 = a + 5; a is then equal to -3
The answer is 8/17 because you have to change the fractions to improper fractions then change the division sign to a multiplication sign. Then change the second fraction by flipping the two numbers then multiply and reduce.
We aer goint to eliminate the x's
multiply first by -5 and 2nd by 2
so that is B
