The answer is: W>-4
I hope this helps
Answer:
-6(3x +2) = 2x -5 -20x -7 (use the distributive property )
-18x -12 = -18x - 12 (i combined like terms on the right side of the equation)
at this point I can tell that it's true for any value of x, so they all apply
Step-by-step explanation:
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:
a, ax3 =b, bx3= c , cx3=d, dx3=e
Step-by-step explanation:
2, 2×3=6, 6x3=18,18 x3 =54, 54x3= 162
Multiplication of three with previous number will give you next number in series.
