9/10 / -3/15
inverting the divisor and multiplying:
= 9/10 * 15 / -3
= 9/10 * -5
= -45 / 10
= -4 1/2
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.
