Answer:
You have to graph and label the points
Step-by-step explanation:
3x-5 is just a straight line which is lesser than or equal to -1 so that is a closed circle
-2x+3 is another straight line which is (both open circle) which its domain is restricted from -1 to 4
2 is just a horizontal line starting at (closed circle) 4, it is greater than also.
If you don't understand the the constants (the numbers on their own) just a vertical translation.
If the cross either the x or y axis, you have to find that too, im pretty sure.
To find the y axis intercept, make x = 0 and solve for y
and to find the x axis intercept, make y = 0 and solve for x
Solve first for the solution of the inequalities. This can be done by replacing first the inequalities sign with the equal sign.
x + y = 1
2y = x - 4
The values of x and y from the system of linear equation are 2 and -1. This means that the intersection of the lines should be at point (2, -1).
Substitute 3 to x and determine the value of y from the second inequality.
2y ≥ x - 4
Substituting,
2y ≥ 3 - 4, y ≥ -1/2
Hence, the solution to this item should be the fourth one.
Find the interquartile range (IQR) of the data set. 1,1,3,4,4,5,5,5,6,7,9
iragen [17]
The interquartile range is 3
Answer:
50
Step-by-step explanation:
Let x represent the number of people that attended the movie.
And y the number of adults that attended the movie
Given;
Percent of adults that attended the movie = 40%
Number of adults that attended the movie y = 20
So,
40% of those that attended the movie area adults.
y = 40% of x
y = 40/100 × x
y = 0.4x
(Ratio of y to x is 4:10 or 0.4)
Making x the subject of formula;
x = y/0.4
Substituting the value of y given;
x = 20/0.4
x = 50
Therefore, 50 people attended the movie.
