Form the ratio 560/2800 and then mult. the result by 100%:
560
--------- * 100% = 20%
2800
Answer:
Step-by-step explanation:Domain is the set of x values in which the function exists. Range is the set of y values in which the function exists. f(x) = 8 / (x + 9) Since the denominator cannot be zero, we set the denominator equal to zero.
We need to solve the following system by substituition:

To solve by substituition means that we need to isolate one variable in one of the equations and replace one expression with the other. This is done below:

Then we need to replace the value of "x" in any of the two equations.

The solution is (-3,-5).
After the total distance on the first, second and third days, Patrick had walked 3.45miles
Answer:
Step-by-step explanation:
Solving Exponential Equations with Different Bases.
Step 1: Determine if the numbers can be written using the same base. If so, stop and use Steps for
Solving an Exponential Equation with the Same Base. If not, go to Step 2.
Step 2: Take the common logarithm or natural logarithm of each side.
Step 3: Use the properties of logarithms to rewrite the problem. Specifically, use Property 5 which
says
Step 4: Divide each side by the logarithm.
Step 5: Use a calculator to find the decimal approximation of the logarithms.
Step 6: Finish solving the problem by isolating the variable.
