Step-by-step explanation:

*)Solve the system of equations:

x+y=19

x-y =5

=> 2y=14 =>y = 7

y=7 => x = 12

Answer:

nevada will earn $300 interest and the total balance after 18 months is $4,300.

Step-by-Step Explanation:

we use this following formula to find how much interest nevada has :

simple interest = principal * interest rate * time

since the amount of time is in months, we have to convert it into years. we use interest in years ONLY.

1 year = 12 months

1.5 years = 18 months

now that we have the correct values to use this formula in, we now substitute the numbers in.

simple interest = principal * interest rate * time

simple interest = $4,000 * 0.05 * 1.5

here, we converted the percentage rate into a decimal because obviously, you cannot directly multiply percentages by money or normal numbers.

simple interest = principal * interest rate * time

simple interest = $4,000 * 0.05 * 1.5

simple interest = $200 * 1.5 (we multiplied the first two values first so it's easier to get the final answer)

simple interest = $300

we now have to find the total balance on nevada's account after 18 months by using the following formula :

total amount = principal + simple interest

since we know the amount of principal and interest already, all we have to do is substitute the numbers in.

total amount = principal + simple interest

total amount = $4,000 + $300

total amount = $4,300

therefore, nevada's total balance on her account after 18 months is $4,300.

Rewrite the form In exponential form:<br> Log100 = x
andrey2020 [161]

Answer:

10^x=100

Step-by-step explanation:

You know how subtraction is the <em>opposite of addition </em>and division is the <em>opposite of multiplication</em>? A logarithm is the <em>opposite of an exponent</em>. You know how you can rewrite the equation 3 + 2 = 5 as 5 - 3 = 2, or the equation 3 × 2 = 6 as 6 ÷ 3 = 2? This is really useful when one of those numbers on the left is unknown. 3 + _ = 8 can be rewritten as 8 - 3 = _, 4 × _ = 12 can be rewritten as 12 ÷ 4 = _. We get all our knowns on one side and our unknown by itself on the other, and the rest is computation.

We know that 3^2=9; as a logarithm, the <em>exponent</em> gets moved to its own side of the equation, and we write the equation like this: \log_3{9}=2, which you read as "the logarithm base 3 of 9 is 2." You could also read it as "the power you need to raise 3 to to get 9 is 2."

One historical quirk: because we use the decimal system, it's assumed that an expression like \log1000 uses <em>base 10</em>, and you'd interpret it as "What power do I raise 10 to to get 1000?"

The expression \log100=x means "the power you need to raise 10 to to get 100 is x," or, rearranging: "10 to the x is equal to 100," which in symbols is 10^x=100.

(If we wanted to, we could also solve this: 10^2=100, so \log100=2)
