Use what you know about the angle sum theorem for triangles and your algebra skills to solve for x and find the measure of all t
melomori [17]

Answer:

2x° = 45°, 3x° = 67.5°

Step-by-step explanation:

Sum of angles in a triangle = 180°

2x+3x+3x=180°

8x=180°

x=22.5°

2x=22.5°x2=45°

3x=22.5°x3=67.5°

Graph the system of inequalities. Show at least two points for each inequality. (Lesson 1.08)
rjkz [21]

The inequalities and the points are

  • y + 2 ≤ 5x: (5, -2) and (10, 1)
  • y + x > -4: (5, -2) and (10, 1)
  • y ≤ 1/3x: (5, -2) and (10, 1))

<h3>How to graph the system of inequalities?</h3>

The system of inequalities is given as:

y + 2 ≤ 5x

y + x > -4

y ≤ 1/3x

Next, we plot each inequality in the system of inequalities using a graphing calculator

See attachment for the graph of the system of inequalities y + 2 ≤ 5x, y + x > -4 and y ≤ 1/3x

From the attached graph, we have the following points:

y + 2 ≤ 5x: (5, -2) and (10, 1)

y + x > -4: (5, -2) and (10, 1)

y ≤ 1/3x: (5, -2) and (10, 1)

I could really use some help with this
denis23 [38]
Since you want help i wont tell you the answer..just how to solve...

(need to know) Of in math means multiply

 they are giving you something to plug in to f(x) so everywhere in the equation there is an X replace with the equation and solve....in this case they are replacing f(x) with f(a+2) so take 3+x and change it to 3+a+2 and then take x-3 and make it a+2-3.

Then you have 3+a+2 divided by a+2-3
