What is the rate of decay of f(x)=200 multiply (0.6)^x

The rate of decay is 40%

Step-by-step explanation:

The decay rate is found by looking at the number raised to the variable. In this case that is the 0.6 but this comes from the general formula f(x) = a(1-decay rate)× so the 200 is your a or your initial amount and the 0.6 comes from subtracting the decay rate from 1 or in other words 0.6=1-decay rate. Thus the decay rate =1 - 0.6 or 0.4 which is 40%

answer: yes youre right.

step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
