The solution to the system of equations, though we can solve using substitution, can also be found by graphing these equations. If you graph these equations, look for where they intersect (it should be one point!).

-5x + 6 = 3x - 2

6 = 8x - 2

8x = 8

x = 1

y = 3(1) - 2

y = 3 - 2

y = 1

Hope this helps!! :)

A regular decagon has 10 sides. How many reflectional symmetries does a regular decagon have?
lina2011 [118]

The rule for regular polygons are very easy. The number of reflectional symmetries is same as the number of sides. Regular polygons have all sides the same length and all angles same. Reflection symmetry means that you can fold the shape along that line and it will match up.

For this question, we want the number of reflectional symmetries of a regular decagon. Decagon is a 10 sided figure. Hence, the number of reflectional symmetries is 10.

There are 5 symmetry lines from one vertex to opposite vertex and 5 more symmetry lines form midpoint of one side to midpoint of opposite side.

Graph the equation below by plotting the y-intercept and a second point on the line. When you click Done, your line will appear
Gala2k [10]

Answer:

Step-by-step explanation:

Equation of the line has been given as,

y=\frac{3}{2}x-5

By comparing this equation with the y-intercept form of the equation,

y = mx + b

Slope of the line 'm' = \frac{3}{2}

and y-intercept 'b' = -5

Table for the points to be plotted on a graph will be,

x              y

-4           -11

-2           -6

0            -5

2            -4

4            -3

By plotting y-intercept (0, -5) and any one of the points given in the table we can get the required line.

Simplify 4 + 3 W equals -5
LuckyWell [14K]

First, we pass the other number subtracting, like this:


3W = -9


Then we pass the number 3 dividing, like this:


W = \frac{-9}{3}


So, the answer is: W = -3.
