The length of JK is 21

This is because JK + IJ = IK so x+6+9=2x

This can be simplified to x+15=2x and then even further to 15=x

Now that you have x, you can plug it into the equation for JK

so 15+6=21

Answer:

So the two sectors add to the full length:

JK + IJ = IK

x+6 + 9 = 2x

Rearrange:

x=15

So the numerical length:

2*15

Choose the point-slope form of the equation below that represents the line that passes through the point (−1, 6) and has a slope

IrinaVladis [17]

Answer:

The correct answer is option B.

Step-by-step explanation:

Two point form of the equation:

$(y-y_1)=\frac{y_2-y_1}{x_2-x_1}\times (x-x_1)$

$\frac{y_2-y_1}{x_2-x_1}=Slope=m$

$(y-y_1)=m\times (x-x_1)$

A line passing through the point (-1,6) with slope ,m = -3.

The equation of the line will be:

$y-6=(-3)(x-(-1))=(-3)(x+1)$

Hence, the correct answer is option B.

I will attach a screenshot of the math problem.

Complete the table for the function y = 0.1^x

The first step: plug values from the left column into the ‘x’ spot in the formula <u>y=0.1^x</u>.

* 0.1^-2 : We can eliminate the negative exponent value by using the rule a^-1 = 1/a. Keep this rule in mind for future problems. (0.1^-2 = 1/0.1 * 0.1 = 100).

* 0.1^-1 = 1/0.1 = 10

* 0.1^0 = 1 : (Remember this rule: a^0 = 1)

* 0.1^1 = 0.1

Our list of values: 100, 10, 1, 0.1

Now, we can plug these values into your table:

$\left[\begin{array}{ccc}x&y\\2&10\\1&10\\0&1\\1&0.1\end{array}\right]$

The points can now be graphed. I will paste a Desmos screenshot; try to see if you can find some of the indicated (x,y) values: [screenshot is attached]

I hope this helped!
