Answer:
y is 8/5 when x = -4.
Step-by-step explanation:
If the value of "Y" varies directly with "X", we can write y = kx, where k is the constant of proportionality.
If "y=-8,when x=20," then we can find k: -8 = 20k, or k = -2/5.
Then y = (-2/5)x.
If x = -4, then y = (-2/5)(-4) = 8/5
y is 8/5 when x = -4.
This is not as hard as it seems. All shapes will follow ratios when they undergo a change in overall size. The first part is finding the size of line G-A. Since we know perimiter, we can simply subtract the other sides from the total permitier. This gives us that GA is 30. Since the ratio of
=
, we can simply do 14/35 = x/30. Sp x = 30*14/35 =12
8x - 3y = 24
y-intercept ⇒ x = 0
subtitute
8 · 0 - 3y = 24
-3y = 24 |divide both sides by (-3)
y = -8
Answer:
to know the average of the data set
Step-by-step explantion:
i dont know :)
Total area of the rectangular land = 2^15 sq. miles
= 32768 sq. miles
total area of the pieces being sold = 8^3 sq. miles
= 512 sq. miles
now total no. of pieces = total area of the land / the area of samaller land that's being sold
= 32768 / 512
= 64
so the actual number of pieces is 64
