On a math test, Stephen missed 3 computation problems and 1 word problem for a total of 9 points off. Brad missed 2 computation problems and 2 word problems for a total of 10 points off. This relationship can be represented by the system of equations below, where x stands for the point value of computation problems missed and y stands for the point value of word problems missed. 3

What is the point value for each word problem?

answer: evaluate the objective function at each vertex to determine which - and -values, if any, maximize or minimize the function. example: find the minimum value and maximum value of the objective function f ( x , y ) = 4 x + 5 y , subject to the following constraints

the answer is  

a.

4,624π mm2

step-by-step explanation:

answer: 8 years

step-by-step explanation:

the explanation is that in 8 years the child will be 20 and in 8 years the father will be 40 and 20 is half of 40.
