Minutes in 4 hours
kilograms in 9 000 g
perimeter of rectangle 5 cm by 4 cm
litres in 8 000 ml

1h = 60min, 4h=4×69=240min

1kg=1000g, so 9000g=9000/1000=9kg

Perimeter= sum of sides. This rectangle has 2 sides of 5cm and 2 if 4cm. Overall: p=2(5+4)=2×9=18cm

1l=1000ml, so 8000ml=8000/1000=8l

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?
