First, distrbute -3 to both -4y and 3
-3(-4y) = 12y -> note that two negatives multiplied = one positive answer
-3(3) = -9 -> note that one negative and one positive = one negative answer
12y - 9 + 7y -> combine like terms
12y + 7y - 9
19y - 9 -> answer
Your answer is 19y - 9
hope this helps

Petri Dish A sees a double ever 10 minutes
Petri Dish B sees a double ever 6 minutes
Consequences
A doubles 60 / 10 = 6 times.
B doubles 60 / 6 = 10 times.
Solution
If you work best with numbers then suppose there are 100 bacteria in both dishes at the beginning
A = 100 * 2^6
B = 100 * 2^10
A will have 100 * 64 = 6400 bacteria growing inside A
B will have 100 * 1024 = 102400 bacteria growing inside B
B/A = 102400 / 6400 = 16
There are 16 times as many in B than in A. <<<< Answer

Answer:
Step-by-step explanation:
perp. -1/2
y + 3 = -1/2(x - 3)
y + 6/2 = -1/2x + 3/2
y = -1/2x - 3/2
Answer:
13k
Step-by-step explanation:
Given: 
Finding the equivalent expression.
We know the rule of addition is that adding two positive integers will give positive result or sum.
Now, lets find the equivalent expression of .
∴ 
Hence, the required equivalent expression is 13k.
