Answer:
-5/33
Step-by-step explanation:
Answer:
y = 
Step-by-step explanation:
Given y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition
x = 3 when y = 7
k = 
= 
, thus
y = x ← equation of variation
When x = 7, then
y = × 7 =
Answer:
A) 59
Step-by-step explanation:
2x+24 = 4x-94
2x+118 = 4x = 2x+2x
2x = 118
x = 118/2 = 59
Answer:
Range of the function → {24, 375}
Step-by-step explanation:
Domain of the function f(x) = 3x³ is {2, 5}
we have to find the range when its domain is {2, 5}
Since x-values of any function define the domain and y-values define the range.
For x = 2,
f(2) = 3(2)³ = 24
For x = 5,
f(5) = 3(5)³ = 375
Therefore, range of the given function for the given domain will be {24, 375}.
