Answer:

It's 3.

Step-by-step explanation:

A line that rises from left to right has a positive slope.

1. confuses me a little because we would say a horizontal line has zero slope - but I guess that's not the same as 'no slope'.

The solution is the point of intersection between the two equations.

Assuming you have a graphing calculator or a program to lets you graph equations (I use desmos) you simply put in the equetions and note down the coordinates of the point of intersection.

In the graph the first equation is in blue and the second in red.

The point of intersection = the solution = (-6 , -1)



If you dont have access to a graphing calculator you could draw the graphs by hand;

1) Draw a table of values for each equation; you do this by setting three or four values for x and calculating its image in y (you can use any values of x)

y = 0.5 x + 2 (Im writing 0.5 instead of 1/2 because I find its easier in this format)

x | y
-1 | 1.5 * y = 0.5 (-1) + 2 = 1.5
0 | 2 * y = 0.5 (0) + 2 = 2
1 | 2.5 * y = 0.5 (1) + 2 = 2.5
2 | 3 * y = 0.5 (2) + 2 = 3

y = x + 5

x | y
-1 | 4 * y = (-1) + 5 = 4
0 | 5 * y = (0) + 5 = 5
1 | 6 * y = (1) + 5 = 6
2 | 7 * y = (2) + 5 = 7

2) Plot these point on the graph
I suggest to use diffrent colored points or diffrent kinds of point markers (an x or a dot) to avoid confusion about which point belongs to which graph

3) Using a ruler draw a line connection all the dots of one graph and do the same for the other

4) The point of intersection is the solution

First divide 32 by 8

32/8

=4

Then multiply the 4 by 3 to find out how many students in the class like to ride their bicycles to school

4x3

-2/3 is a rational number
0.1111.... =1/9 - rational number

-2/3*1/5= -2/15 rational

1/9*1/5=1/45 rational
correct answer A and  D

π and √11 are irrational numbers, and  when they are multiplied by rational number,  they will give irrational number.

Interior angles of triangles equal 180.

So angleTUV = 24 degrees

A straight line will equal 180 degrees. If angle U is 24 degrees in the interior angle, the exterior is 156 degrees.

Angle VUX is 156 degrees
