1515 of the book was read in 112112 hours.
1 of the book will be read in 112112/1515 hour
1212 of it will then be read in: ( 112112 /1515)* 1212
= ( 112112 /1515)* 1212 use calculator
= 89689.6 hours.
Hope this clarifies it.
Try using the back of the book.
<u>X AND Y INTERCEPTS</u>
1st Answer:
x = 9
Step-by-step explanation:
<u>first you want to substitute the y</u>
<h3>
0 = -2 √(25 - x + 8)</h3>
<u>move the expression to the left</u>
<h3>
2 √(25 - x) = 8</h3>
<u>divide both sides</u>
<h3>√25 - x + 4</h3>
<u>move the constant to the right</u>
<h3>
25 - x = 16</h3>
<u>calculate</u>
<h3>
-x = -9</h3>
<u>change the signs</u>
<h3>
x = 9</h3><h3>
</h3>
2nd Answer:
x = -65/9 OR x = - 7 2/9, x = - 7.2
Step-by-step explanation:
<u>first you want to substitute the y</u>
<h2>
0 = -3 √(x + 9) = 4</h2>
<u>move the expression to the left</u>
<h2>
3√(x+9) = 4</h2>
<u>divide both sides</u>
<h2>
√(x+9) = 4/3</h2>
<u>move the constant to the right</u>
<h2>
x = 16/9 - 9</h2>
<u>calculate</u>
<h2>
x = -65/9</h2>
