Answer:

The equation of line is: y = 7

Step-by-step explanation:

point = (-8, 7)

slope = 0

Using the point-slope form

$y-y_1=m\left(x-x_1\right)$

where m is the slope, and (x₁, y₁) is the point

substituting the values m = 0 and the point (-8, 7)

$y-y_1=m\left(x-x_1\right)$

$y-7 = 0(x-(-8))$

$y-7 = 0$

$y = 7$

Thus, the equation of line is: y = 7

Jade invested in the stock market. The weekly change in value of her stock, in dollars, over 4 weeks was +23.65, -22.20, -12.75

Answer:

<h3>The average weekly change in value of Jade's stock in dollars is -1.3225</h3>

Step-by-step explanation:

Given that Jade invested in the stock market.

The weekly change in value of her stock, in dollars, over 4 weeks was +23.65, -22.20, -12.75 and +5.98.

<h3>To find the average weekly change in value of her stock in dollars :</h3>

The average weekly change in value of Jade's stock is given by $Average=\frac{sum of the weekly changes in value of her stock in dollars}{total number of weeks}$

$Average=\frac{23.65+(-22.20)+(-12.75)+5.98}{4}$

$=\frac{23.65-22.20-12.75+5.98}{4}$

$=\frac{29.63-34.92}{4}$

$=\frac{-5.29}{4}$

$=-1.3225$

Therefore Average=-1.3225

<h3>Therefore the average weekly change in value of Jade's stock in dollars is -1.3225</h3>

Answer:

If a polygon is convex, then the sum of the measures of the exterior angles, one at each vertex, is 360° .

Consider the sum of the measures of the exterior angles for an n -gon.

N=180n−180(n−2)

Distribute 180 .

N=180n−180n+360 =360.

SOLVE each system by graphing PLEASSE

dexar [7]

Answer:

Step-by-step explanation:

The given equations are:

$y=-\frac{1}{3}x+3$ and $y=2x-4$

On solving $y=-\frac{1}{3}x+3$ , we get the graph which is red in colour.

By Putting x=o in the equation⇒y=3

Putting x=-3⇒y=4

Now, plotting the graph for the equation $y=2x-4$ , it is plotted as blue colour by putting x=0⇒y=-4 and by putting x=3⇒y=2, Following the same path, we can plot the two graphs for the given equations.
