8u+3<19 subtract 3 from both sides

8u<16 divide both sides by 8

u<2 so

-9 is in the solution set u=(-oo, 2)

1 Subtract 3 from both sides

19−3>8u
2 Simplify 19-3 to 16

16>8u

3 Divide both sides by 8

16/8 > u

4 Simplify 16/8 to 2

2 > u

5 Switch sides

u < 2

I hope this helps. :)

A pole is used to support an observation platform. The top of the pole is secured by two guy wires, one 18 and the other 21 feet

We can conclude that the the two wires at the points where they are anchored are 21 feet apart. Check the procedures in the picture attached.

Graph the two lines 2x + 3y = 18 , 3x -4y > 16.

Dmitrij [34]

The domain and range for each line is all real numbers. This is because all numbers are possible to input into x and all y values exist.

The slope of the first line is -2/3 and the y intercept is 6. You can reach this conclusion by solving for y (putting it in slope intercept form).

The slope of the second one is 3/4. and the y intercept is all real numbers greater than -4. This is true because it is an inequality and you can find these numbers by solving for y.
