Answer:

-9 + -11=-20

Step-by-step explanation:

Since subtracting is the same as addition of the oppositie, just putting a negative symbol is easier because you are only working with negative numbers, instead of one negative and one positive.

Did that help?

Answer:

-20

Step-by-step explanation:

it’s just solving it, nothing special

-9+-11

(I made it addition ti make it easier, why, because if there’s a problem that doesn’t make sense right away make it addition, to make it addition just make the signs opposite, Ex: -3-5, we keep -3 and make the negative sign before the 5 into addition and now to make that equal we turn the now positive 5 into negative 5 so final result is -3+-5 which is much easier and you’ll get -8.

5x/x^2-9 + 7/x+3<br> Simplify
rjkz [21]

5x ÷ x² - 9 + 7 ÷ x + 3

Write the division as a fraction:

\frac{5x}{x^{2} }\\ - 9 + \frac{7}{x} + 3

Simplify the expression:

\frac{5}{x} - 9 + \frac{7}{x} + 3

Calculate the sum:

\frac{5}{x} - 6 + \frac{7}{x}

Write all numerators above the common denominator:

\frac{5 - 6x + 7}{x}

Add the numbers and you get the final answer:

\frac{12-6x}{x}

Which exponential function grows at a faster rate than the quadratic function for zero is less than X is less than three
Ann [662]

Answer:

43.35 years

why?

From the above question, we are to find Time t for compound interest

The formula is given as :

t = ln(A/P) / n[ln(1 + r/n)]

A = $2500

P = Principal = $200

R = 6%

n = Compounding frequency = 1

First, convert R as a percent to r as a decimal

r = R/100

r = 6/100

r = 0.06 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(2,500.00/200.00) / ( 1 × [ln(1 + 0.06/1)] )

t = ln(2,500.00/200.00) / ( 1 × [ln(1 + 0.06)] )

t = 43.346 years
