Answer:
y = 1/3*x -3
Step-by-step explanation:
Method 1:
Grab two random points from the line.
(0,-3) and (3,-2)
Using the Point-Slope Form solve for m.
(-3 - (-2)) = m * (0 - (3))
-1 = m * (-3)
m = 1/3
Turning Point-Slope form into Slope intercept Form.
(y - (-3)) = 1/3 * (x - 0)
y + 3 = 1/3x
y = 1/3 - 3
Method 2:
Look at the y-intercept since y-int becomes our b. b = -3
From the y-int count rise/run as thats our Slope m. m = 1/3
Slope-intecept Form:
y = 1/3*x -3
The number of bacteria that will exist in 12 hours is 614,400.
That’s a irrational number
Answer:
C. Sqrt(12^2+9^2)
Step-by-step explanation:
Pythagorean theorem is
x^2+y^2=z^2
So solving for z
z=sqrt(x^2+y^2)
z=sqrt(9^2+12^2)
-4 and -9 is the correct answer
