PLS HELP! Solve and graph, y=1/3x-1 pls!!!!!!! show steps

Mathematics
1 answer:
yaroslaw [1]3 years ago
5 0

Answer:

See below for a graph.

Step-by-step explanation:

The equation of the line is in slope-intercept form. The slope is the coefficient of x, 1/3. The y-intercept is the added constant, -1.

These mean the line goes through the point (0, -1) on the y-axis and increases by 1 unit vertically for every 3 units of positive horiontal movement. These facts can help you draw the graph.

The steps are:

  • identify the y-intercept on the coordinate plane
  • find a point that is 3 units to the right and 1 unit up
  • draw the line through these two points.

Which shows the best use of the associative and commutative properties to
OlgaM077 [116]

Answer:

D

Step-by-step explanation:

So the associative and commutative properties basically say That you can change the orders of the numbers and the answer won't change (for multiplication and addition).

Your answer would be D because they added the numbers with a decimal place together, it makes it easier to look at, and add in your head.

<h3><u>given</u><u>:</u></h3>

<u>10 ^{2y}  = 25</u>

<h3><u>to</u><u> </u><u>find</u><u>:</u></h3>

<u>{10}^{y}  = .......</u>

<h3><u>solution</u><u>:</u></h3>

<u>10 ^{2y}  = 25</u>

<u>(10y {)}^{2}  =  {5}^{2}</u>

A circle has a circumference of 10. It has an arc length of 9/2. What is the central angle of the arc in degrees?
dem82 [27]

Answer: The central angle of the arc is 162 degrees.

Step-by-step explanation: The information available are as follows;

Circumference of the circle equals 10. Length of an arc equals 9/2. The circumference of a circle is given as;

Circumference = 2Pi x r

That means 2Pi x r = 10.

Also the length of an arc along the same circle is 9/2. Length of an arc is calculated as;

Length of arc = (X/360) x 2Pi x r

Where X is the central angle of the arc

That means;

9/2 = (X/360) x 2Pi x r

We can now substitute for the known values as follows

Length of an arc = (X/360) x 2Pi x r

9/2 = (X/360) x 10

9/2 = 10X/360

By cross multiplication we now have

(9 x 360)/(2 x 10) = X

3240/20 = X

162 = X

The angle at the center of the arc is 162 degrees.
