Answer:
no solution
Step-by-step explanation:
5 + 2(3 + 2x) = x + 3(x + 1) ← distribute parenthesis on both sides
5 + 6 + 4x = x + 3x + 3 , simplify both sides
11 + 4x = 4x + 3 ( subtract 11 from both sides )
4x = 4x - 8 ( subtract 4x from both sides )
0 = - 8 ← false statement
This indicates the equation has no solution
Answer:
Step-by-step explanation:
Mode is the number that appears most often in a set, so for this one the mode would be 3 since it appears the most often
I’m assuming ‘dives further’ means to go directly down
the angle of elevation of the ship from the submarine is equal to the angle of depression of the submarine from the ship, if we assume the sea level is perpendicular to ‘directly down’.
let both of these angles to be = $ when the submarine is at A and ¥ when the submarine is at B (excuse the lack of easily accessible variables as keys)
then this become a simple trig problem:
A)
Let O be the position of of the ship, and C be the original position of the submarine.
therefore, not considering direction
|OC| = 1.78km = 1780m
|CA| = 45m
these are the adjacent and opposite sides of a right angled triangle.
But tan($) = opp/adj = |CA|/|OC| = 45/1780
therefore $ = arctan(45/1780) which is roughly 1.45 degrees,
B)
similarly, noting that |CB| = |CA| + |AB| = 45 + 62 = 107m
tan(¥) = 107/1780
¥ = arctan(107/1780) which is roughly 3.44 degrees

Answer:
-2x + 4y - 2z
Step-by-step explanation:
as you can see, the graph indicates which axis belongs to x, y, and z and also gives information on the positive and negative directions of each axis.
to get the answer, all you have to do is find each coordinate,
x is at -2, y is at +4, and z is at -2.
