Answer:

m = -6

Step-by-step explanation:

As we move from point (1,4)​ to point (3,-8)​, x increases by 2 and y decreases by 12.  Thus, the slope of this line is m = rise / run = -12/2 = -6.

Answer: ⁻6 is your answer.

Step-by-step explanation:

To find the slope use the slope equation: m=y₁-y₂/x₁-x₂

Sub: m= ⁻8-4/3-1

Solve: m= ⁻12/2

Sam: m= ⁻6/1 or -6

Answer:

y = x - 4

Step-by-step explanation:

In y = ax + b form, a is the slope and b is the y intercept so a = 1 and b = -4, thus y = x - 4

1. y = sin? (In x). Find dy
galina1969 [7]

Answer:

dy/dx=  cos(ln(x))/x

Step-by-step explanation:

y=sin(ln(x)) given

We have to use chain rule to differentiate!

Let u=ln(x) then du/dx=1/x

So we have

if y=sin(ln(x)) then y=sin(u) and dy/dx=dy/du * du/dx=cos(u) *1/x

where again u=ln(x) so

dy/dx=cos(ln(x)) *1/x

dy/dx=cos(ln(x))/x

I hope I have the right intepretation because I do see a ? in between sin and (ln(x)) .

Which of the following is a solution of x2 + 2x + 4?
RideAnS [48]

Answer:

option-D

Step-by-step explanation:

we are given

x^2+2x+4

Let's assume it is equal to 0

x^2+2x+4=0

We can use quadratic formula

Suppose, we are given quadratic equations as

ax^2+bx+c=0

x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

we can compare and find a,b and c

a=1 , b=2 , c=4

now, we can plug values

and we get

x=\frac{-2\pm \sqrt{2^2-4\cdot \:1\cdot \:4}}{2\cdot \:1}

now, we can simplify it

and we get

x=-1+\sqrt{3}i,\:x=-1-\sqrt{3}i
