Answer:
t >= 2.
Step-by-step explanation:
3t+ 9 >= 15
3t >= 15 - 9
3t >= 6
t >= 6/3
t >= 2.
Answer:
x = 2 and y = -1
Step-by-step explanation:
that is the solution above
Since x and y are directly related, the equation for their comparison will look like
kx = y
where k is your constant. They give you an instance in the problem where x = 27 and y = 81. Plug this into the above equation and solve for k.
kx = y
k (27) = 81
k = 3
Thus, the constant of variation is 3.
You can always find a percent by setting up a fraction
and then doing the division.
To set up the fraction, the top number is some percent of the bottom number.
If 400 is some percent of 30, then the fraction is
400 / 30 .
Do the division: 400/30 = 13.333...
To turn a number into a percent, move
the decimal point two places that way ===> .
13.333... = 1,333.333 %
400 is (1,333 and 1/3) percent of 30 .
i think it would be y+8=1/5(x+3)
Step-by-step explanation:
point slope formula is y-y1=m(x-x1)
slope=m
m=1/5
