The answer is A hope this helps
To do this problem you would first need to factor out a variable, which in this case I would want to do the first equation because it is isolated. Now the equations would look like this:
x = -2y - 1
4x - 4y = 20
Since we know that x is now equal to -2y - 1 we can plug it in to the x value in the second equation:
4 (-2y -1) - 4y = 20
-8y -4 - 4y
-12y - 4 = 20
-12y = 24
y = -2
Now that we know the y value plug the y value to one equation to find the x, I will be using the first equation
x + 2(-2) = -1
x - 4 = -1
x = 3
Solutions:
y = -2
x = 3
Just combine like terms: all of the x^2 together, all of the x's together and all of the numbers:
3x2+5x2+5x-2-1
8x2+5x-3 simplified, so letter A
Answer:
The answer is C.
Step-by-step explanation:
Answer:
62
Step-by-step explanation:
20% as a decimal is 0.2
For each year get the amount of increase by multiplying the number of rabbits by 0.2
Rabbits in 2013:
25 x 0.2 = 5
25 + 5 = 30 rabbits
Rabbits in 2014:
30 x 0.2 = 6
30 + 6 = 36 rabbits
Rabbits in 2015:
36 x 0.2 = 7.2
36 + 7.2 = 43.2
Rabbits in 2016:
43.2 x 0.2 = 8.64
43.2 + 8.64 = 51.84
Rabbits in 2017:
51.84 x 0.2 = 10.368
51.84 + 10.368 = 62.208
= 62 rabbits
