Answer:
6.1 units²
Step-by-step explanation:
area of a triangle= 0.5b*h
b=2
h=6.1
6.1*2=12.2
12.2*0.5= 6.1

Answer:
1.1
Step-by-step explanation:
slope = (-4-7)/(-6-4)= -11/-10 = 1.1
Hello there, and thank you for posting your question here on brainly.
To find mean absolute deviation, (MAD) you have to add all the numbers together, and then divide by how much numbers are in the set.
So we have to do 10 + 11 + 15 + 16 + 18, and then divide by 5.
10 + 11 + 15 + 16 + 18 ===> 70
Now, divide by 5.
70 / 5 ===> 14
The mean absolute deviation is 14.
Hope this helped! ☺♥
Answer:
Step-by-step explanation:
Use substitution, y=3x+18 so -12x+4(3x+18)=-24. From here you can try to solve for x
-12x+12x+72=-24
The xs cancel, which leaves you with 72=-24
Since 72 cannot equal -24 there is no answer to this system of equations
