Answer:
(-4-y) = -6(7 - x)
Step-by-step explanation:
We define variables:
x = represent the width of the field
y = represent the length of the field
We write the perimeter (with no fencing along the river):
2400 = 2x + y
We clear y:
y = 2400-2x
Answer:
an expression for the length of the field as a function of x is:
y = 2400-2x
Answer:
f(x)=4^x exponential growth, -6^x exponential decay Step-by-step explanation:
In a polynomial, each constant (regular number) has a degree of 0. For example, 8 is really 8x to the power of 0.
