Let us assume the two unknown numbers to be "x" and "y".
Then
x + y = 37
And
xy = - 210
x = - 210/y
Now let us put the value of "x" in the first equation, we get
x + y = 37
- (210/y) + y = 37
y^2 - 210 = 37y
y^2 - 37y - 210 = 0
y^2 - 42y + 5y - 210 = 0
y(y - 42) + 5(y - 42) = 0
(y - 42)(y + 5) = 0
So when
y - 42 = 0
y = 42
Then
x = -(210/42)
= - 5
Again when
y + 5 = 0
y = -5
Then
x = 42
So the two unknown numbers are 42 and -5. I hope the procedure is clear enough for you to understand.
Y = mx + b
m = slope
b = intercept
So if you make it into that it's
y = 2/3x - 5
So then you get the slope as -5 and also the slope as 2/3
The answer is B. an = 13 + 14(n-1)
Answer:
21785.1548486
Step-by-step explanation:
The growth rate is expressed by,
m'(t)=27t
when t=2days,
m'(2)=27*2
m'(2)=27*2
= 54*
= 21785.1548486
