Answer:
y = -8x + 4
Step-by-step explanation:
Using the y = mx +b for the slope intercept form, the m stands for the slope and the b stands for the y-intercept.
In this case, the slope is -8 and the y-int is 4 so we naturally plug those in
Quadratic function ( in standard form ):
y = a x² + b x + c
x = 0:
635 = 0 + 0 + c
c = 635
x = 1:
644 = a + b + 635
a + b = 9
x = 2:
719 = 4 a + 2 b + 635
4 a + 2 b = 84
and now we have a system:
a + b = 9 / * ( - 2 )
4 a + 2 b = 84
-------------------------
- 2 a + 2 b = - 18
+
4 a + 2 b = 84
-------------------------
2 a = 66
a = 33; b = - 24;
Function is:
f ( x ) = 33 x² - 24 x + 635
f ( 8 ) = 33 * 64 - 24 * 8 + 635 = 2,112 - 192 + 635 = 2,555
Answer: The number of waterfowl on week 8 would be 2,555.
Answer:
I will just give you the way of solving it
Step-by-step explanation:
First you have to change the sgape of the equation and it will become like this :
-6y=-2x+12
And then:
Y=0.33x+2
And then you have to give values to x and find y
For example i will make x zero (0)
It will become
Y=0.33(0)+12
=+12
And the points are (0,+12)
Go on like this and draw the line
Good luck
Sorry for bad english
Answer:
position: (-6, -4)
range: 6
Step-by-step explanation:
The equation is that of a circle centered at (-6, -4) with a radius of √36 = 6. We presume that the "position" is that of the circle's center, and the "range" is the radius of the circle.
___
The standard form equation of a circle with center (h, k) and radius r is ...
(x -h)^2 +(y -k)^2 = r^2
Matching parts of the equation, we find ...
h = -6, k = -4, r = √36 = 6.
