Y = f(x) = -3x
y = -3x
y = (constant) x
y is proportional to x.<span>
Hence we can say Y is proportional to x , having (-3) as proportionality Constant. hope this helps</span>
Answer:
3.5
Step-by-step explanation:
Use proportions here - 8/5.2 = 96/width of actual car. using cross multiplication, 5.2*96 = 8x. this gives you 499.2 = 8x. divide both sides by eight to get x=62.4. the width of the actual car is 62.4 inches.
Answer:
a = 64
Step-by-step explanation:
The geometric mean of 2 numbers a and b is
, then
= 16
( square both sides )
28a = (16
)² = 1792 ( divide both sides by 28 )
a = 64
