Martin is giving a math test next period. the test, which is worth 100 points, has 29 problems. each problem is
worth either 5 points or 2 points. write a system of equations that can be used to find how many problems of each
point value are on the test.
leta be the number of questions worth 5 points and let y be the number of questions worth 2 points,
** 29.5+ 2y 100
pya 100, 5r+ 2y = 29
5*y * 29,2+=100
2x+y=100, 5y +2= 29

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?

answer is the third choice:
