There are 12 months in a yr so 12/3=4 then 1/3x4=4/3 so 1ft and 1/3 erode each yr. C is the correct answer<span />
Answer:
y = 3x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y - 3x = 4 ( add 3x to both sides )
y = 3x + 4 ← in slope- intercept form
with slope m = 3
Parallel lines have equal slopes, thus
y = 3x + c
The line crosses the y- axis at (0, - 3 ) ⇒ c = - 3
y = 3x - 3 ← equation in slope- intercept form
Answer:
216 ft
Step-by-step explanation:
you multiply 12 and 18
Step-by-step explanation:


5(a-3)(a-3)
5(a-3)^2

X^4(2x+1) - (2x+1)
(x^4-1)(2x+1)
(x^2-1)(x^2+1)(2x+1)
(x-1)(x-1)(x^2+1)(2x+1)
