Change the 90 min to hours it will be 1 and a half hours
Speed =distance divide by time
3.5 divide by 1 and a half
=2.33 miles per hour
8953.7 is the answer to this
The number of cells of strain A follow the linear model
, where
denotes the number of cells of that strain and
is time in hours. Meanwhile, strain B follows
. The time
when both strains have the same number of cells is the intersection of these two lines, or the solution to
You have
so after 5 hours, both strains should have the same number of cells.
Answer:
[4, -1]
Step-by-step explanation:
Using the Elimination Method:
3x + y = 11
5x - y = 21
__________
8x = 32
__ ___
8 8
x = 4 [Plug this back into both equations to get the y-coordinate of -1]; -1 = y
The <em>y</em>'s are already <em>additive</em><em> </em><em>inverses</em><em> </em>[result in 0], canceling each other out.
