Answer:
im pretty sure all you have to do is switch the signs (if its negative it will become positive) but only for the points on the x axis so basically (-12,13) would become (12,13)
Answer:

Step-by-step explanation:
3u=y/x^2-d^2
3u=y-(xd)^2/x^2
u=y-(xd)^2/3x^2
The volume of a triangular prism is V = 1/2 x a x c x h where a is height of the triangle, c is the base of the triangle and h is the height of the prism.
120 = 1/2 x a x c x h; we write a from the previous equation in terms of c and h thus,
a = 240 / ( c x h)
If the dimensions where halved then a = a/2 ; c = c/2 ; h=h/2
We use the volume formula again and substitute the given values to find the new volume,
V = 1/2 x a/2 x c/2 x h/2
Substitute the previously determined a term,
V = 1/2 x (240/2ch) x c/2 x h/2
We cancel and evaluate the constants therefore the new volume is,
V= 15 cm^3
Answer:
The inequality is 
Step-by-step explanation:
Let
x -----> amount of water that can be used by only one family member for the rest of the month
we know that

Solve for x
Subtract 4,885.78 both sides


Divide by 6 both sides
---> maximum amount of water that can be used by only one family member for the rest of the month
Answer:

Step-by-step explanation:
Let y represent the given situation.
Given:
Andrew's age = a
We need to find the expression for given abatement.
Solution:
The given statement: Five years less than four times Andrew’s age
Five years less than four times Andrew’s age = 
Andrew's age is known, so we substitute Andrew's age = a


Therefore, the expression for the given situation
