To answer this question, you would need a protractor, which is a device that measures angle. Because this is a picture, I cannot help you. I'm sorry....
What I can tell you is that the angle is less than 90 degrees.
Hopefully this helped! I used the substitution method
Question B) you want to take 0.75, divide it to both sides and you get m= 21 0.75m=15.75 m = 21 ___________ = 0.75
answer: -5x+12=20
-12 -12
-5x/-5= 8/-5
x= -1.6
Check: rewrite the orignal problem
plug your variable
Answer:
-4 ≤x≤1
Step-by-step explanation:
Increasing means that as x goes from left to right, the y value is getting larger
The graph is increasing from -4 to 1
-4 ≤x≤1
