Solve the top equation to get on variable on one side
2x-y=6
-y=-2x+6
y=2x-6
then plug in the coordinate for x and y for both equations. if both equations are true then it’s a solution
2=2(2)+6
2=10
4+2=6
so it’s not a solution
Answer:
D
Step-by-step explanation:
the square root of 24 is 4.8 so it has to be D
3,806,000 is the correct answer.
There are three in the millions place and 806 in the thousands. There are no numbers in the hundreds so you place zeros.
A^2 + b^2 = c^2
a^2 + 9^2 = 18^2
a^2 + 81 = 324
a^2 = 243
a = 15.589 = 15.6 feet is the angle the ladder is at :)
