Answer:

An equation of the form y = kx can be thought of as an equation of the form y = mx + b where m = k and b = 0.

What is the equation of the line connecting (1,5) and (4,14)?
german
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?

there are 225 wolves in a state park the population is increasing at the rate of 15% per year you want to make a prediction for
erastova [34]
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.

Solve 7(z +2) - 3z =44
maw [93]
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
