Answer:
No solutions. You can’t have a negative absolute value.
15 degrees below zero = -15
25 degrees above zero = 25
25 + 15 = 40
It rose 40 degrees.
3:27
And another one would be
9:81
If it si proportional
y/x=k or y=kx
if k is same throuout, then it is proportional
find their ratio
so
0/0=undefined, ignore
2/3=k
4/6=2/3=k
6/9=2/3=k
yes, proportional
y=kx
3=2k
1=2/3k
2/3 is answer
proprtional (2nd and 3rd)
graph is proprtional, first table is poroprtional
other ones are not
2nd picture is proportional, 3rd is not
(x,y), y is rise, x is run
unit rate is rise/run=15/6=5/2=2.5
unit rate is 2.5
unit rate is (1/2)/(2/5)=(1/2)(5/2)=5/4=1.25
unit rate is 1.25
