Answer:
150
Step-by-step explanation:
Since y is directly proportional to sqrt((x+2)^2), there is a constant,k, such that
y=ksqrt((x+2)^2)
We are given a pair (x,y) in this relation. Let's plug in (8,250 ) to find k.
250=ksqrt((8+2)^2)
250=ksqrt((10)^2)
250=k10
250/10=k
25=k
So for any pair (x,y) we have the relation y=25((x+2)^2).
We are asked to find y when x=4.
y=25((4+2))^2
y=25(6)
y=150
Test to see if y is proportional to sqrt((x+2)^2)
For the given points: 250/150=10/6
The equation is true so we're great.
Answer:
It's D because 2y and 0.5x both have a vrible besilde it .
Answer:
x3+5=6
2x + 4 = 10
9−3x=0
Step-by-step explanation:
C is a non terminating decimal.
a = 0.75
b = 0.8
c = 0.333333 (and will never terminate)
