$\frac{3}{6} = \frac{x}{8}$ What is $x$ ?
Multiply diagnally 3×8= 24, divide it by the other number or 6, 24÷6= 4
$x= 4$

What is a disadvantage of overpaying your taxes during the year?

Otrada [13]

The disadvantage of overpaying your taxes during the year is that you cannot use the money or draw interest on it until after you get your tax refund.

If you are overpaying your taxes, the government is holding that extra money for you. At the end of the tax year when you file your taxes, they will give you the extra money back that you overpaid.

However, you don't receive any interest on the extra money that was held.

Contains the point (-1, 2) and is parallel to<br> x – 2y = -3

ivanzaharov [21]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange x - 2y = - 3 into this form

Subtract x from both sides

- 2y = - x - 3 ( divide all terms by - 2 )

y = $\frac{1}{2}$ x + $\frac{3}{2}$ ← in slope- intercept form

with m = $\frac{1}{2}$

• Parallel lines have equal slopes, thus

y = $\frac{1}{2}$ x + c ← is the partial equation

To find c substitute (- 1, 2) into the partial equation

2 = - $\frac{1}{2}$ + c ⇒ c = 2 + $\frac{1}{2}$ = $\frac{5}{2}$

y = $\frac{1}{2}$ x + $\frac{5}{2}$ ← in slope- intercept form

Multiply through by 2

2y = x + 5 ( subtract 2y from both sides )

0 = x - 2y + 5 ( subtract 5 from both sides )

- 5 = x - 2y, thus

x - 2y = - 5 ← in standard form
