Ax+by=c
y+4= -1/3(x-12)
remove ( )
y+4= -1/3x+4
subtract 4
y=-1/3x+0
add 1/3x
1/3x+y=0
hope this helps
Simplify the expression.
2x^3-10x^2+22x-14
Answer:
12 ft
Step-by-step explanation:
You have a right triangle with the hypotenuse = 13 and one leg = 5
Let x = distance above the ground that the ladder touches the wall
Now use the Pythagorean theorem
It looks like none of the choices are correct, because the answer is 12 ft.
By the way, it is impossible for the ladder to reach up the wall a distance longer the the length of the ladder. Think about it. OK?
