Answer:
h(4z)=4+12z / 5+4z
Step-by-step explanation:
The function h is defined by h(x)=4+3x over 5+x
This can be written as
h(x)=4+3x / 5+x
The value of the function at any time depends on the value of x. x is the independent variable. The variable,x can take any value at any time.
To find h(4z), it means that x is taking the value of 4z.
We will substitute 4z in the place of x in the function. This becomes
h(4z)=4+3×4z / 5+4z
h(4z)=4+12z / 5+4z
You have to divide the 5 and 5x by 5 add your variables together in alpha order=1
Total length of boards needed = 2000*3.5 = 7,000.
Total number of 8' boards needed = 7000/8 = 875 answer
Answer:
A)
Step-by-step explanation:
As exponential functions grow faster than polynomial functions and linear function, A is the only answer that makes sense.
