Answer:

the graph in the attached figure

Step-by-step explanation:

we have

x-y-2\geq 0

Isolate the variable y

-y\geq -x+2 -----> Multiply by -1

y\leq x-2

The solution of the inequality is the shaded area below the solid line

The equation of the line is y= x-2

The slope of the line is positive

The y-intercept of the line is the point (0,-2)

The x-intercept of the line is the point (2,0)

Using a graphing tool

the graph in the attached figure

To be able to graph any equation, simply solve for y.

You should get y ≤ x - 2          
[the sign switched because you needed to divide by -1 in order to solve for y all the way]

Then use -2 as your y-intercept. This is the point that is at (0,y) on a graph. From the origin, just go down 2 points, and mark your point. 

X is the same as 1/1 x. This is your slope. From point -2, <em>rise</em> 1 point, then <em>run</em> 1 point to the right (because it is positive). From that position, mark another point. You now have enough to make a line, which gives you the completed look of the graph for this equation. 

It should look like this:

Anna said that the product of 7/8 times 1 1/2 equals 7/2. How can you tell that her answer is wrong?
gregori [183]

Answer:

Her answers wrong because the product of 7/8 times 1 1/2 equals 21/16.

Step-by-step explanation:

1 1/2=3/2

7/8*3/2=(7*3)/(8*2)

Answer:

x=12

Step-by-step explanation:

we know that

A linear pair is two angles that are adjacent and form a line. The angle measure of a line is 180 degrees

In this problem we have that

(10x-20)^o+(6x+8)^o=180^o --- by supplementary angles (form a linear pair)

solve for x

(16x-12)=180

16x=180+12

16x=192

x=12
