Answer:
y ≤-1/2 x-1
y < -4x+25
Step-by-step explanation:
The y intercept is -1
The slope is negative since the line goes down from left to right
The line is y = -1/2 x -1
The line is solid so there is an equals in the inequality
The graph is shaded below the line
y ≤-1/2 x-1
Question 5
The y intercept is 25
The slope is negative since the line goes down from left to right
The slope is (y2-y1)/ (x2-x1) = (49-25)/(-6-0) = 24/-6 = -4
The line is y = -4 x +25
The line is dotted so there is NOT an equals in the inequality
The graph is shaded below the line
y < -4x+25
22^4=22x22x22x22
22^7=22x22x22x22x22x22x22
This means that 22^7 is greater and by the amount of 22^3
