Answer:
x = -6
x = 2
Step-by-step explanation:
x² + 4 - 12 = 0
= (x + 6)(x - 2)
x + 6 = 0
x = -6
x - 2 = 0
x = 2

Step-by-step explanation:
you dont say the numbers in words all the time, so it makes a lot more sense.
Answer:
5
Step-by-step explanation:
The interquartile range is the difference between the upper quartile and the lower quartile.
First find the median.
The median is the middle value of the data set arranged in ascending order
1 5 5 7 9 ← data in ascending order
↑ median
The lower quartile is the middle value of the data to the left of the median. If there is not an exact middle then it the average of the values on either side of the middle.
1 5
↑ lower quartile =
= 3
The upper quartile is the middle value of the data to the right of the median.
7 9
↑ upper quartile =
= 8
Thus
interquartile range = 8 - 3 = 5
Answer: y<1x-2
Step-by-step explanation:
Find some coordinates on the line to write a slope intercept form equation for the line and turn it into inequality.
First we need to find the slope and the y-intercept. The y intercept is when x is 0 and as we can see it already indicates that the y intercept is -2 .
(0,-2)
(2,0) Use these points o the find the slope.
0- 2 = -2
-2 -0 = -2
-2/-2 = 1 The slope is one so the equation will be y = 1x - 2 But since this is not an inequality we have to change the equal to sign to an inequality sign.
Looking at the line, it is a dashed line so the inequality sign will be > or <
The painted side of the graph represents the solutions of the graph and that is all underneath the graph so the inequality will be y < 1x-2
