To find the slope of the line:
(y2-y1)/(x2-x1)
(14-5)/(4-1)=(9)/(3)=3
Only one of your 4 possible answers has 3 as a slope. However, plugging in each point into the y=mx+b equation, the y-intercept consistently comes out as 2..
y=mx+b
14=3(4)+b b=2
5=3(1)+b b=2
y=3x+2
If there is a consistent, positive slope (from your question, this does not seem to have a quadratic as an option), 3x+5 is not even a viable solution because x=1 when the y-value is 5 (and thus no other x value {0} could have a y-value of 5). It seems as though you have a typo on your hands. Hopefully this helps?
Answer:
For the first page (doesn't show the number), it is the third option.
For the second page (doesn't show the number), it is also the third option.
For the third page or number 15, it is the second option
For the fourth page or number 12, it is the second option
For the fifth page or number 11, it is the second option

Well, here is how i would do it.
We start with 225, at a rate of 15% per year. Assuming your answers are in years and not months, we will increase by this increment; years.
So, we start with 225, and a 15%, or .15, increase. So what we would do, it take 225 times .15. One way ive learned to do this (via algebra class) is that you can times it by 1.15 to make it quicker, this just takes out the adding step.
So after one year, we would have a total of 258.75, or about 259 wolves.
after two years, we would have about 298 (we cant have a half of a wolf!)
after 3 years, we would have about 343 wolves.
after 4 years, we would have about 394 ish
after 5 years, we would have about 453
after 6 years, we would have about 521.
So, it would take about 5 and a half years, if thats an option choice.
Answer: 97/20 or 4 17/20
Step-by-step explanation:
5/1 - 3/20 = 97/20, to an improper fraction gives 4 17/20
7(z +2) - 3z =44
Distribute the 7. Distributive property: a(b+c) = ab + ac
7z + 14 - 3z = 44
Simplify like terms.
4z + 14 = 44
Subtract 14 to both sides
4z = 30
Divide by 4 on both sides.
z = 7.5
