Answer:

You can (a) use the old t-table approach; (b) you can draw a line and then figure out its slope and y-intercept; or you can (c) first explain the slope-intercept formula and then explain how the equation aligns with the formula.

OR.

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y).

Julli [10]

Answer: $398.5750$

Step-by-step explanation:

It is important to remember that the fourth digit after the decimal point is in the ten-thousandth place.

Then, given the following number:

$398.574986215$

You can follow these steps in order ti round it to the nearest ten-thousandth:

1. You can identify that the digit in the ten-thousandth place is:

$9$

2. Identify the digit to the right of $9$ . This is:

$8$

3. Since:

$8>5$

You must round up. Increase the digit $9$ by 1. (Notice that $9+1=10$ , then the digit to the left of $9$ increases by 1 too). Then:

$398.5750$

Show a reciprocal numerical expression for each equation using multiplication, please!

iris [78.8K]

$\frac{2}{3}$ ÷ 4 = $\frac{2}{3} \times \frac{1}{4} = \frac{1}{6}$

$\frac{1}{8}$ ÷ 3 = $\frac{1}{8} \times \frac{1}{3} = \frac{1}{24}$

$\frac{3}{4}$ ÷ 6 = $\frac{3}{4} \times \frac{1}{6} = \frac{1}{8}$

$\frac{1}{36}$ ÷ 2 = $\frac{1}{6} \times \frac{1}{2} = \frac{1}{12}$
