First go to the Algebra Calculator main page.
Type the following:
<span><span>First type the expression 2x.</span><span>Then type the @ symbol.</span><span>Then type x=3.</span></span><span>Try it now: </span><span>2x @ x=3</span>
Answer:
when the input is 3 the output is 1
Step-by-step explanation:
inputs would basically be the x coordinates while outputs are the y coordinates. when you put in the x coordinate of 3, the y coordinate of 1 is what shows up as the output. (3,1) are the coordinates on the line
To the nearest ten, 829 would become <em><u>830</u></em> because the ones digit (9) is closer to 30 than it is to 20. So we would round up.
To round to the nearest hundred, we look at the tens and ones digit. 29 is less than 50 so we would have to round down to <em><u>800</u></em> instead of rounding up to 900.
Hope that helps :)
17.601 = <span>1 × 10 + 7 × 1 + 6 × 1/10 + 0 × 1/100 + 1 × 1/1000
