Your answer is D for your purposes

Work:

Multiply b and 5

Multiply b and 1

The b just gets copied along.

5*b evaluates to 5b

Multiply b and 6

Multiply b and 1

6*b evaluates to 6b

6*b-10 evaluates to 6b-10

Multiply 5b by 6b-10

Multiply 5b by each term in 6b-10 term by term.

This is the distributive property of multiplication.

Multiply 5b and 6b

Multiply the b and b

Multiply b and b

Combine the b and b by adding the exponents, and keeping the b, to get b²

5b × 6b =

Multiply 5b and -10

Multiply b and 1

5b × -10 = -50b

5*b*(6*b-10)

***The final answer is 30b²-50b***

Erwin earns $ 2 , 100 per month. Her deductions amount to 26 % of her paycheck. How much does Erwin take home each month?
Sergeu [11.5K]

Answer:

Credit ⇒ 45

Debit ⇒ $30

Step-by-step explanation:

Credit = $45

Debit = $30

When an account balance increases it means that it has been credited and when it decreases, it has been debited.

The beginning balance here is $0 and the closing balance is $15.

There were 2 transactions, one credit and one debit.

For the closing balance to be $15, the Credit amount must have been $15 more than the Debit amount.

9 × 1/5 is the answer greater than or less than 9 and why
Vikentia [17]
When u multiply by a fraction, you get a smaller number. Multiplication means<span> “of,” especially with fractions. So 0.2 × 9 means, “0.2 of nine”—and that’s smaller than nine. Hope that helps

What is the equation of the following line? Be sure to scroll down first to see
Rom4ik [11]
<h2>Answer:</h2>

-1/3x

<h2>Step-by-step explanation:</h2><h3>Known :</h3>
  • x1 = -3
  • x2 = 0
  • y1 = 1
  • y2 = 0

<h3>Asked :</h3>
  • Correct line equation

<h3>Solution :</h3>

We can find the straight line equation using this formula,

\frac{y-y1}{y2-y1} = \frac{x-x1}{x2-x1}

Insert all we know inside the formula,

\frac{y-1}{0-1} = \frac{x-(-3)}{0-(-3)}\\\frac{y-1}{-1} = \frac{x +3}{3}\\

Use cross multiplication,

3(y - 1) = -1(x + 3)\

3y - 3 = -x - 3

3y = -x - 3 + 3

3y = -x

y = -1/3x

<h3>Conclusion :</h3>

The correct equation is y = -1/3x
