Predict how much water will be in the bucket after 14 hours if Franklin doesn\u2019t stop the leak.<br \/>\n_______ quarts<\/p>\n<p>Answer:<br \/>\n23 quarts<\/p>\n<p>Explanation:<br \/>\nSubstituting the value of slope (m) and (x, y) in the slope-intercept form to find y-intercept (b)<br \/>\ny = mx + b<br \/>\n5 = 1.5(2) + b<br \/>\ny-intercept b = 2<br \/>\nSubstituting the value of the slope m and y-intercept in the slope-intercept form. y = mx + b where, m = 1.5 and b = 2.<br \/>\ny = 1.5x + 2<br \/>\nThe x value is 2<br \/>\ny = 1.5(2) + 2 = 23<br \/>\nThere will be 23 quarts after 14 hrs.<\/p>\n<h3>Conclusion:<\/h3>\n<p>Every expert&#8217;s choice is utilizing Go Math Grade 8 Chapter 5 Writing Linear Equations Answer Key PDF.
