Answer:
- y < -2x +3
- y > 1/2x -2
Step-by-step explanation:
To find the equation of each boundary line, look for the y-intercept. Then find the rise and run to the next grid intersection to the right that is crossed by that line. The equation for the line is ...
y = mx + b . . . . . . m = rise/run = slope; b = y-intercept.

The lines are both dashed, so the inequalities will not include the "or equal to" case. For line (1), the shading is below the line, so the appropriate inequality symbol is <. For line (2), the shading is above the line, so the appropriate inequality symbol is >.

<u>Line 1</u>
y-intercept = +3. m = -2/1 = -2
y < -2x +3
<u>Line 2</u>
y-intercept = -2. m = 1/2
y > 1/2x -2
Answer:
The green box is -3
Step-by-step explanation:
You are reading from a graph, so it is more important perhaps, to pick clear points rather than easy to handle points.
The easiest two points you could use would be
(0,4)
(1, 1)
Slope
m = (y2 - y1)/(x2 - x1)
y2 = 4
y1 = 1
x2 = 0
x1 = 1
m = (4-1)/(0 -1)
m = 3/-1 = - 3
Y intercept
b = 4 from the point 0,4
Line
y = - 3x + 4
Your answer would be 3 an 3/5 :) hope i helped ! :D:D:D:D:D:D:D
Answer:
Ur question?
Step-by-step explanation:
Answer: The measures of all the three angles are 24 , 60 and 96
Step-by-step explanation:
Since the measures are given in ratio form, the first thing is to find the total ratio, which is
2 + 5+ 8 = 15
Recall that the sum of angles in a triangle is 180 ,so to calculate each angle , we have
2/15 x 180 = 24
also , 5/ 15 x 180 = 60
Finally, 8/15 x 180 = 96
The triangle is obtuse , since it is having one angle greater than 90.
It can not be acute because of the existence of 96 , for a triangle to be acute , all the angles must be less than 90 , and it can not be right triangle because there is no existence of 90
