Answer:
d. 15-(-18)
Step-by-step explanation:
Take the second point and subtract the first point
15 - (-18)
15 + 18
33
If you multiply 4 by 4 tenths, the answer is 1.6
tenth = 0.1
four tenths = 0.4
4(0.4) = 1.6
The answer for the first one is (-2,-3) because if you put a point there, then it would make a right triangle and, if ou take the x term from the higher point and the y term from the lower point and put them togeteher, then you get (-2,-3)
if you mean directly proportional where x/y=k where is x goes up, y goes up as well so try them out
first one: x/y=k 1/11=k does 3/23=k as well? no so this is not proportional
second one: x/y=k 1/2=k does 3/-10=k as well? no, so this is not proportional
third one: x/y=k 1/-6=k does 3/-22=k asl well? no, so this is not proportional
fourth one: x/y=k 1/-8=k does 3/-24=k as well? yes, so this is the proportiona one
subsitute
if x=1 and y=7
try the first
7=1+7
false so the first one doesn't work
try the second
7=1-7
false, so the second one doesnt' work
third
7=1/7
false so the third one doesn't work either
try the fourth
7=(7)(1)
7=7
true so this is the naswer
7=7 tue
