Answer:
y = -240
Step-by-step explanation:
If y varies jointly as x and z, then y/(xz) = k where k is the constant of proportion
60/10(-3) = 60/-30 = -2 = k
Now, y/(xz) = -2
y/8(15) = -2
y/120 = -2
y = -240
For these similar figures we can write, ratios of their corresponding sides
GH/EA = JI/EA, because GH=JI
JI/EA = y/HI
9/20.25 = y/5
y=9*5/20.25≈ 2.2
Answer:
Step-by-step explanation:
y=4x
