7x + 5y = -13

Mathematics
1 answer:
lana [24]4 years ago
7 0

Answer:

x = 0.36     y = -3.1

Step-by-step explanation:

(7x + 5y = -13)2

(-2x - 7y = 21)7

14x + 10y = -26

-14x - 49y = 147            Add both equations together

       -39y = 121             Divide both sides by -39

        y = -3.1

Plug -3.1 in for y into one equation

7x + 5(-3.1) = -13

7x -15.5 = -13

    +15.5    +15.5           Add 15.5 to both sides

7x = 2.5                        Divide both sides by 7

x = 0.36

Let f(x)=18/1+3^e-0.1x What is the point of maximum growth rate for the logistic function f(x)? Show all work. Round your answer
xz_007 [3.2K]

Answer:

(0, 4.5)

Step-by-step explanation:

*The equation can be put into Desmos, to find the point, but the work to prove it is here*

f(x)=c/1+Ae^-Bx

Y=C

C=18      A=3      -B=-0.1

*Replace x with 0 in the equation, so you know 0 is the x value, and it leads you to the y value*

f(0)=18/1+3e^-o.1(0)

= 18/1+3e^0

=18/1+3(1)

=18/1+3

=18/4

=4.5

x=0    y=4.5

Maximum growth rate = (x,y) --> (0, 4.5)

Hope this helps:))!!
