Answer: I'm not sure about the first question, I've never been good at equations. The second one is asking for 15x30 = 450. She will make 450 dollars for 15 hours of work.

Answer:
It's D.
Step-by-step explanation:
If you want me to explain it, I will. But it seems like you need the answer fast. So if you still don't understand it later, then I will try to explain it...but it'll take some time. :)
All you have to do is move all the points to the right 6 numbers because it says x+6. For example, A is (-5,-1). Move to the right 6 times, so (-5+6,-1) which is (1, -1). So the new point of A is (1, -1). Do the same with the others. Now that we got the new rectangle in the fourth quadrant, you want to move it counterclockwise around the origin, which is 0. Clockwise is like a clock, it goes around the middle going to the right. Counterclowise is the same, except it goes to the left around the middle of the clock. You can sort of apply that to this. Go counterclockwise around the middle, in this case being the origin, 0. Move the rectangle up to the first quadrant because counterclockwise is going around to the left. So, if the rectangle goes around to the left, then that means that it is now vertical...because it turns to the left making it straight if you go counterclockwise. Now the point A is on the bottom left because the rectangle got turned. If you turned it properly, then A should be at (1,1). Apply the same thing to the other points. D is the only one with point A being at the point (1,1), so that is correct. Check the other points anyway.
Answer:
22.) y = -1/7x + 8/7 23.) y = 2x -3 (x is the slope.)
Step-by-step explanation
22.) Divided each side by 7. Subtract 1/7x from each side to get the eqaution.
23.) Divided each side by 3. Add y to each side. then subtract 9 from each side to get the equation.
Answer:
G = kX
Where:
G - Growth rate
X = the initial/current population of rabbit
k = is the constant of proportionality.
Step-by-step explanation:
As we are told in the question, the growth rate is proportional to the current population. This information gives us the initial value needed to solve to find the population of rabbits at any given time.
Other information given as needed for computation and we are not asked to do anything further.
<u>Analytically,</u>
If X = 100
And it triples in 2 years. That is, 3*X = 300. 2 years is 24 months.
This gives us the monthly growth rate = 300/24 = 12.5 => 12 to 13 rabbits per months.
Foxes kill 2 rabbits per month. This implies that 2*24 = 48 rabbits are killed by Foxes in 24 months.
By implication, the population of rabbits in 2 years will be
X (in 2 years) = 300 - 48 = 252 rabbits.
