Find the gradient
m = y2-y1 / x2-x1
m = 4-(-2) / 3-(-3)
m = 6 / 6
m = 1
Insert the values of one of the points into y=mx+c to find c (choosing point (3,4)):
y = mx + c
4 = 1(3) + c
c = 4 - 3
c = 1
Therefore, the equation is:
y = x + 1
<span> A: y=2x 15 (or whatever variables you choose to represent the colony growth and time)
B: y=2(3.5) 15;
22 colonies
C: substitute 584 with y into the original equation, so:
584=2x 15
569=2x
284.5=x; therefore, after 284.5 hours</span> Hope this helps! :D
Answer: -6xy -7y +4x +9
Step-by-step explanation:
Firstly, distribute y to 6x + 7: -6xy - 7y
Next, collect like terms: 4x + 9 -6xy - 7y = -6xy -7y + 4x + 9
Answer and Step-by-step explanation:
To solve for r, we need to get everything away from r. We can start off by moving five thirds, and pi.
Multiply each side by 
, then divide by 
(pi)
Now, take the cubed root of both sides.
![\sqrt[3]{\frac{3x}{5\pi } } = r](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B%5Cfrac%7B3x%7D%7B5%5Cpi%20%7D%20%7D%20%20%3D%20r)
^^ That is the answer.
