Answer: 19 ft
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the Pythagorean Theorem:
c^2 = a^2 + b^2
Where c is the hypotenuse of the triangle (in this case the length of the ladder) and a and b are the other sides.
Replacing with the values given:
20^2 = (4 1/2)^2 + x^2
400=20.25 + x ^2
400-20.25 = x^2
379.75 = x^2
√379.75 = x
x = 19.48
x= 19 ft
Feel free to ask for more if needed or if you did not understand something.
50 + (3x - y) = x + (2x - 16). Combine like terms to change the 2nd part to get 3x - 16. 50 + 3x-y = 3x - 16. Subtract 3x from both sides to get 50 - y = -16. Subtract 50 from both sides to get -y = - 66, or y = 66. 90 - 50 = 40 = 3x - 66. Add 66 to both sides to get 3x = 106, or x = 35 1/3.

Answer:
Step-by-step explanation:
y is NOT a function of x because there is not a unique y for each x.
The vertical line through these three points is
x = 3
