Answer:y = 65x/z
Step-by-step explanation:
Suppose y varies directly with x and inversely with z. It means that as y increases or decreases, y increases or decreases while z decreases or increases respectively.
In order to remove the variation symbol and replace with an equation symbol, we would introduce a constant of variation, k. It becomes
y = kx/z
When x= 65 and z=5, then y= 26. We would substitute these value to get the constant of variation, k. It becomes
26 = 65k/5
65k = 65
k = 1
The equation of combined variation will be
y = 65x/z
Answer:

Step-by-step explanation:
we know that
The equation of a exponential growth function is equal to

where
P is the population
t is the time in years
a is the initial value
r is the rate of change
<u><em>Looking at the table</em></u>
For t=0
The value of P=1,000
so
substitute the value of the ordered pair (0,1,000) in the exponential equation

The initial value is a=1,000
substitute

For t=1
The value of P=1,400
so
substitute the value of the ordered pair (1,1,400) in the exponential equation

therefore
The exponential equation is

Answer:
16
Step-by-step explanation:
7x+14=6x+30
Move x into one side and whole numbers to the other.
Solve like linear equation.
7x+14=6x+30
7x-6x=30-14
x=16
