Slopes of perpendicular lines are opposite reciprocals of each other. The slope of the given equation (which is in slope-intercept form) is 1, the invisible coefficient of x. The opposite reciprocal of 1 is -1, thus the slope of a line perpendicular to the line y = x + 4 is -1.
Hope this helps.
Start by proving to them that the number 0.57 can be converted into a fraction . A whole number can't exactly be put in to a fraction. 0.57 can be converted to 14.25/25. This information means that 0.57 IS a rational number. Hope this convinced them!
Answer:80
Step-by-step explanation:
Ur answer is: -2a² + 7a + 1
You have to look to the tenths place. You then look at the number right behind it. In this case you look at the 5, and then the number behind it a 9. If the number behind is 5+ you bring the left number up. So .59 is rounded to the nearest .1 meter as .6!
