Losing Weight for Wrestling Phil wants to lose weight for his wrestling team so he can compete in a different weight . The equation below represents his weight loss joumey: y = - 2.5x + 181 x = number of weeks y = total weigtht (pounds) How much will Phil weigh after 4 weeks ?

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

c
