The standard form is 3x+4y=8
Answer:
19.1 feet
Step-by-step explanation:
Length of the ladder = 20 feet
Distance from the ladder to the wall = 6 feet
Height of the ladder on the wall = x
x² + 6² = 20²
x² = 20² - 6²
x² = 364
x = 19.1 feet (Rounded to nearest tenth)
Answer: -16
Step-by-step explanation:
f(g(x)) = 2(4(-2)) + 5
f(g(x)) = 2(-8) + 5
f(g(x)) = -16 + 5
f(g(x)) = -11
f(0) = 2(0) + 5
f(0) = 5
f(g(x)) - f(0) = -11 - 5
f(g(x)) - f(0) = -16
