Answer:
Step-by-step explanation:
<h2>y = 8</h2><h2 />
y varies directly as x
y ∞ x
y=14 when x=3.5
y = kx
k is a constant, when multiplied by x, you get y
14 = 3.5k
Solve to find k:
14/3.5 = k
14/3.5 = 4
k = 4
y = 4x
Find y when x=2
y = 4x
y = 4(2)
<h2>y = 8</h2>
when there is no number with redical sign here it is equivalent to the exponent " 1/2 "
but when it is 3 under redical x that means it is x^1/3
In first one 8 ^(9/2) is same as ( redical 8 ) ^9
In part B it is (3 under redical 125)^9 = ( 125 )^ 9/3 so this also same thing
In part C it is ( 12)^2/7) but the ( redical 12 ) ^7 is equal to ( 12)^7/2 so these two are not equivalent
in part D it is 4^1/5 but ( redical 4) ^5 = 4^( 5/2 which is also not equivalent
Answer : only A and B are equivalent
Answer:
3 Tenths / 0.3
Step-by-step explanation:
you add 1+2 and get 3 then to put it in standard from you put the 3 in your tenths place in your decimal and a 0 in front of your point
