Answer:
121
Step-by-step explanation:
1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 + 21 is a sum of first 11 odd numbers.
Here, n is the number of terms.
In this sequence, there are 11 terms.
Sum of first 11 odd numbers = 11²
= 11 *11
= 121
Answer:
1.3

The answer for this question would be 28
Step-by-step explanation:
the delimiter line is going through the points (-4, 0) and (0, -4).
the line function
y = mx + b
m is the slope of the line, b is the y-intercept (the y value when x = 0).
the slope is the ratio of "y coordinate change / x coordinate change" when going from one point to another.
so, for the 2 found points :
x changes by +4 (from -4 to 0)
y changes by -4 (from 0 to -4).
the slope m is then
-4/+4 = -1
and the y-intercept is -4 (as explained).
so, the line is
y = -x - 4
and the graphic says that all values greater than our equal to the line values are valid, so
y >= -x - 4
