Answer:
is a function
Step-by-step explanation:
Any linear relation involving both x and y is a function.

<em>Additional comment</em>
A line of the form x=constant is the only sort of line that is not a function. As you can see, it does not involve y, which is why I put the restriction in the above statement.
Answer:
A = 846 in²
Step-by-step explanation:
The area (A) of a rhombus is calculated as
A = 
× d₁ × d₂ ( d₁ and d₂ are the diagonals ) , then
A = × 36 × 47 = 18 × 47 = 846 in²
Decompose each velocity in its i and j - coordinates.
1) River's velocity
3.5 m/s, west fo east = 3.5i + 0j
2) Luke's velocity
5m/s, 60° east of north
5* sin(60°) i + 5*cos(60°) j = 4.33 i + 2.5 j
3) Resultant velocity
[3.5i + 0j] + [4.33i + 2.5j] = 7.83i + 2.5j
resultant speed = √[ (7.83)^2 + (2.5)^2 ] = 8.22 m/s
angle = arctan(2.5 / 7.83) = 17.7° north of east (equal to 72.3° east of north).
Answer:
3.1 kilometers
Step-by-step explanation:
Mark me as brainliest if this helps!
Passes through (4,3) slope = 2
y - y1 = m(x - x1)
y - 3 = 2(x - 4)
y - 3 = 2x - 8
y = 2x - 5
