In 1 hour you'll have 4 cells so multiply that by 3 and you will have 12 cells in 3 hours
Answer:
a
Step-by-step explanation:
Recall that the "point-slope" form of a linear equation may be expressed as
y = mx + b,
where m is the gradient.
If m is negative, the gradient is negative.
If m is positive, the gradient is positive.
In our case, if we consider option A,
x + 3y = -2 (rearranging)
3y = -x -2
y = (-1/3) x - (2/3)
if we compare this to the general equation at the top, we can see that
gradient, = m = (-1/3) which is negative.
hence option a has a negative gradient.
Answer: I’m pretty sure it’s 3/4
Step-by-step explanation: you just count the difference of the x and y and then put the change of y over the change of x and that’s the slope. Also known as the m in y=mx+b
Answer:
4x/5-2
Step-by-step explanation:
Answer:
4
Step-by-step explanation:
Each box is 1 larger than the earlier one, so the boxes are 1, 2, 3, 4, and 5.
4 + 5 is the width across the bottom
2 + 3 is the width across the top (not counting h)
9 - 5 = 4, so h = 4
