Step-by-step explanation:
U = (x - 5)
V = y^3
because we follow the rule
(U+V)^2 = U^2 + 2UV + V^2
factor the expression will be
Mr. Valenzuela’s new bottle of shampoo contains 60 ounces of shampoo. He uses ounce of shampoo each time he washes his hair. Whi

Answer:
Step-by-step explanation:
Total amount of shampoo = 60 ounces
Amount of shampoo used in 1 wash = 1 ounce
Amount of shampoo used in x washes = x ounces
So, Remaining amount of shampoo = 60-x
We are given that 24 ounces will remain in the bottle
So, equation becomes :
Hence equation can be used to find x, the number of washes after which 24 ounces will remain in the bottle is

Answer:
m = 1/3
b = -6
Step-by-step explanation:
How to calculate slide (m):
x1 = 0
x2 = -12
y1 = -6
y2 = -10
If we put in the values:
Subtracting a negative number is the same as adding it:
-6 + 10 = 4 and 0 + 12 = 12 so now we have this:
Lets simplify:
4 and 12 can both be divided by 3:
3 and 1 are prime numbers and cannot be simplified further.
Now we know that m=1/3
Since:
y = mx + b
y = -6
x = 0
m = 1/3
Then:
-6 = 1/3*0 + b
1/3*0 is 0, so we can just remove that part:
-6 = b
that means b is equal to -6
