Answer:
Step-by-step explanation:
P1 = (2000, 1000) in the form (x1,y1)
P2 = (2012, 3400) in the form (x2,y2)
m = (y2-y1 / x2-x1)
m = ( 3400-1000 ) / (2012 - 2000)
m = 2400 / 12
m = 200
y = 200x + 800
Answer:
Option B
Step-by-step explanation:
Rewrite each of the options given to us in standard form. That way we can identify the parabola properties of each -
Right away you can tell that the second option is correct. The vertex is known to be ( - 9, 8 ) and extends at an exponential rate of 2. This is our solution, <u><em>Option b!</em></u>
Answer:
y = 2x - 3
Step-by-step explanation:
We are given the slope, m = 2
Our standard formula of a line is y = mx + b, so we can substitute for the x and y values of the point (3, 3). If you did not know, the x-value and the y-value are both 3 because the point (3, 3) = (x, y).
So, our equation looks like this:
3 = (2)(3) + b
We can solve for b:
3 = 6 + b
b = -3
And now we have our equation of a line:
y = 2x - 3
Answer:
32.
Step-by-step explanation:
This is an arithmetic sequence with first term a1 = -6 and common difference 2.
an = a1 + d(n - 1)
a20 = -6 + 2(20-1) = 32
