<span>You can round to different levels when estimating. Rounding to the nearest hundred, 1400 x 6 would be 8400 (1000 x 6 = 6000, 400 x 6 = 2400). To the nearest thousand, the estimate would be 6000. This is less accurate an estimate.</span>
The dog snored nine times. 1/3 of an hour is every 30 minute interval. 30 min + 30 min = 1 hour. Multiply this x3, and the answer is nine. A simpler way of thinking about this is 3 x 3 or 3 squared.
They have to be at least 40 abut less than 70, so 40 < (underlined) x < 70.
<span>They have to be at least 60 inches but less than 75 inches tall, so 60 < (underlined) y < 75. </span>
<span>Graph the following lines: </span>
<span>x = 40 </span>
<span>x = 70 (dotted) </span>
<span>y =60 </span>
<span>y= 75 (dotted) </span>
<span>The square the four lines make is the answer. I hoped that help!</span>
(15 - 3x^2)!
Just find the square root of 225 and 9. It's 15 and 9! However, make sure to add the - sign because it's -9x.
Hope that helps!

I believe that b<span>. y= -1/2x+3 , y= 2x-3 is the correct answer</span>
