Answer:
A) The 75 is the initial number of cells, and the 2 indicates that the number of cells doubles every minute
Step-by-step explanation:
When x=0 (no minutes have elapsed), the value of the function is ...
f(0) = 75(2^0) = 75(1) = 75 . . . . the initial number of cells
As x increases by 1 (minute), the number of cells is multiplied by 2, so the 2 is the multiplier each minute. It indicates the number doubles. ("double" = "multiply by 2")
x is not defined, but for the function to make any sense, it must represent elapsed minutes.
Answer:
P=40
a + b + x = P
a = 3x
b = x + 5
substitute for b & y
3x + (x+5) + x = 40
Step-by-step explanation:
longest section 1 = a
mid length section 2 = b
shortest section 3 = x
P=40
a + b + x = P
a = 3x
b = x + 5
substitute for b & y
3x + (x+5) + x = 40
5x + 5 = 40
5x = 35
x = 7
b = 12
a = 21
Answer:
Line UM.
Step-by-step explanation: you can name a line by naming at least two points on it.
Answer:
-1
Step-by-step explanation:
We can use the formula to find slope
(y2-y1) / (x2-x1)
y1 is the first Y coordinate in the first pair
y2 is the second one in the first pair
X1 is the first X coordinate in the frst pair
x2 is the second one In the second pair.
so if we put it together it’d look liek this
(5- (-) 2) / (-4 - 3)
5+2 / -4 + -3
7/-7
or -1
