Answer:
34
Step-by-step explanation:
So if your equation was x squared +2x+1=0 you would do (x+1)(x+1)=0 because 1+1=2(x)
then you do x+1-1=0-1 to check it over
Answer:
x = s, y = t, z = 8 -s -t
Step-by-step explanation:
It can work reasonably well to let s and t represent any of a pair of the variables. In the answer above, we have used x=s, y=t.
You could get more elaborate if you want:
x = 4-s, y = 4-t, z = s+t

Answer:
1. y=2x-9
5. y = | x | + 6.5
6. y = | x – 5.5 |
7. y = | x + 8|
Step-by-step explanation:
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.
