What is the least common multiple (LCM) of 4 and 15? A. 19 B. 20 C. 60 D. 30

C

Step-by-step explanation:

Multiples of 4: 4,8,16,20,24,28,32,36,40,44,48,52,56,60

Multiples of 15: 15,30,45,60

Th smallest number that they both can multiply to is 60

is this part of a question or something

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?
