1. the matrices show the enrollment of boys and girls on the basketball, lacrosse, and soccer teams in two towns. (a) if we let matrix a be the matrix for town a, what is the element , and what does it represent? (b) if we let matrix b be the matrix for town b, what is the address of the element that represents the number of girls enrolled in basketball in town b? (c) what is the matrix that results when you subtract matrix a from matrix b? (d) name the matrix you found in part (c) matrix c. what is element , and what information does it tell you about the number of girls enrolled in lacrosse in town b compared with town a? (e) what is the matrix that shows the enrollment in town a after a 12.5% increase in enrollment in all sports and in both genders? (hint: find 1.125a.)

answer: a

step-by-step explanation:

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
