To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.
x-intercept - (3,0)
y-intercept - (0,12)
Slope: -4
Y-intercept: 12
Answer:
-10x + 1.5
Step-by-step explanation:
Answer:
The last answer; 12.
Step-by-step explanation:
In order to solve this, use substitution. Since it gives you an equation for y, substitute that equation in the other formula as y. This will give you:
Then simplify:
Since 6x - 6x cancels out, you are left with 12.

Answer:
A
Step-by-step explanation:
Given
3
When the culture was created t = 0, thus
3
= 3 × 1 = 3
That is there were initially 3 bacteria in the culture → A
