Is the slope of the line best fit positive, negative, zero or undefined
hello : 1.8
the number is 1.5% of 120 is : ( 1.5×120)/100 = 1.8
5. y = | x | + 6.5
6. y = | x – 5.5 |
7. y = | x + 8|
there is not enough given information for some of the problems. here are the solutions and reasons for those that area solvable:
write a perpendicular line to the equation -3x-6y=17 by finding its slope and then flipping it to the negative reciprocal:
so -3x-6y=17 becomes y=-1/2x-17/6 where m = -1/2. the perpendicular slope is 2.
using the point given, write the equation in point slope form and simplify to the slope intercept form:
when translating functions, remember:shifting left or right is addition and subtraction respectfully inside the function.shifting up and down is addition and subtraction respectfully outside the function.
5. a translation of 6.5 units up is +6.5 outside the function y=|x| so equation y=|x|+6.5 is the translation.
6. a translation of 5.5 units to the right is - 5.5 inside the function y=|x| so equation y=|x-5.5| is the translation.
7. a translation of 8 units to the left is +8 inside the function y=|x| so equation y=|x+8| is the translation.
a. -¼(1+ 2y)
-(½y + ¼) = -½y - ¼
-¼(1+ 2y) = -¼ - ½y = -½y - ¼
b is wrong. ¼(2y - 1) = ½y - ¼
c is wrong. -2(¼y - ⅛) = -½y + ¼
d. is wrong. 2(⅛ - ¼y) = ¼ - ½y = -½y + ¼
