Let f(x) = x^2 + 6x.
rusak2 [61]

Answer:

(A) The slope of secant line is 18.

(B) The slope of secant line is h+16.

Step-by-step explanation:

(A)

The given function is

f(x)=x^2+6x

At x=3,

f(3)=(3)^2+6(3)=27

At x=9,

f(9)=(9)^2+6(9)=135

The secant line joining (3,27) and (9,135). So, the slope of secant line is

m=\dfrac{y_2-y_1}{x_2-x_1}

m=\dfrac{135-27}{9-3}=18

The slope of secant line is 18.

(B)

The given function is

f(x)=x^2+6x

At x=5,

f(5)=(5)^2+6(5)=55

At x=5+h,

f(5+h)=(5+h)^2+6(5+h)=h^2 + 16 h + 55

The secant line joining (5,55) and (5+h,h^2 + 16 h + 55). So, the slope of secant line is

m=\dfrac{h^2 + 16 h + 55-55}{5+h-5}

m=\dfrac{h^2 + 16 h }{h}

m=h+16

The slope of secant line is h+16.

I will like to know how to solve this
Alexxandr [17]
This is a linear equation in x.

So you need to group like terms

1 + 4x =  - 5 + 7x
Let us group the x terms on the Right Hand Side of the equation and the constant terms on the Left Hand Side.

1 + 5 = 7x - 4x
We can now simplify

6 = 3x
Now let us divide both sides by 3.

\frac{6}{3}  =  \frac{3x}{3}

This implies that

2 = x
or

x = 2
Let us our answer

1 + 4(2) =  - 5  + 7(2)

1 + 8 =  - 5 + 14
9 = 9
Good we are right

Here is a list of numbers.
max2010maxim [7]

Answer:

-0.3, -0.12, -0.03, 0.15

Step-by-step explanation:

-0.3 is the least because 0.3 = 0.30 and 0.30 is greater than 0.12, -0.12 is the second one because it is 0.12 behind 0 and is greater than -0.03. 0.15 is the last one because it is the only positive number therefore is the greatest one.

really hope this helps and isn't confusing but I'm pretty sure this is correct!
