Answer:
i think the answer is, A...
A. Blue: y = -3x + 8
Black: y = 3x + 2
B. You find the ordered pair (x, y) that is a solution for both functions ( find the point where the two lines cross)
C. There’s two ways you can solve algebraically (using the equations); substitution and elimination. I don’t know which you need to use to answer but feel free to use my notes on how to do substitution for help. I don’t really have any on elimination ( it’s so easy you don’t even really need notes) or I would use them to explain.
Answer:
make25 men
Step-by-step explanation:
20 assembled 8 so divide 4 into 20 = 5
Divide 4 into 8 =2.
So it take 5 men to assemble 4
20 +5=25
X1 = 3-(square root of 64) divided by 14
X2 =3+(square root of 64) divided by 14
Answer:
25,132.74 miles
Step-by-step explanation:
Hello!
We are basically asked to find the circumference of the Earth's cross-section.
Circumference: 
We can replace 2r with the diameter, because the diameter is 2 times the radius.
Multiply the Diameter by pi:
It is around 25,132.74 miles around.
