A 12 foot ladder leans against the side of a house, as shown in the figure above. The point of intersection between the ladder and the house is 9 feet 6 inches above the ground, and the base of the ladder is 2 feet 6 inches from the
base of the house.
To the nearest inch, what length of the ladder, x, extends above the point where the ladder meets the house?

А
1 foot 11 inches
B
2 feet 1 inch
С
2 feet 2 inches
D
2 feet 3 inches

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

so then what are you asking?
