Answer:
possible answers below!
Step-by-step explanation:
if they are vertical angles then the measure of ZB is 78
if they are supplementary then ZB is 102 degrees
if they are complementary then ZB is 12 degrees
It depends on where its located, cant really help if i dont have a pic..but i hope this helps! :)
The graph that matches the given equation is y≥x-1 is Graph A.
Option: C.
<u>Step-by-step explanation:</u>
The given equation y≥x-1 is a linear inequality equation.
Graphing Linear Inequalities differs from graphing regular linear equations. That is it has certain rules to be followed to draw the graph.
- First, rearrange the equation as y in the left and other terms in the opposite side.
- Check for the line: y= , y≤ and y≥ comes with straight line where as y< and y> comes with a dotted line.
- Shading: If y> greater than or y≥ greater than or equal is present then the space above the line has to be shaded. If y< less than or y≤ less than or equal is present then the space below the line has to be shaded.
For the given equation y≥x-1,
The line will be solid passing through (0,-1) and (3,2) since it has y≥. Also, the region above the line is shaded.
So the graph A is the graph that matches the equation y≥x-1.
5(n) - 2 = 3
3 · 9(m) =27
1. is 27
3^2(s)= 9 · 5(t) = 45 · 2(r) = 90
2. is 90
-1.....if the number on the left is smaller than the number on the right change the the number on the right to equal the same on the left then however many numbers down you went make that a negative and that’s your answer
Answer:
<em>x=60°</em>
<em>x=48°</em>
<em>x=21°</em>
Step-by-step explanation:
<u>Inequalities</u>
The sum of the exterior and the interior angle of a triangle is 180°.
The measure of an exterior angle of a triangle is called x, thus the interior angle is 180-x.
This angle is said to be at least twice x, thus:
180 - x ≥ 2x
Adding x:
180 ≥ 3x
Dividing by 3:
60 ≥ x
Swapping the inequality:
x ≤ 60°
The measure of x must be less or equal to 60°.
Three possible solutions are:
x=60°
x=48°
x=21°
