PLS HURRY The number f of miles a ship is from its destination x hours after starting a voyage is given by f(x) = 120 - 30x. The

nadezda [96]

Answer:

120 miles in 4.8 hours

75 miles in 5 hours

Step-by-step explanation:

Ship:

The number f(x) of miles a ship is from its destination x hours after starting a voyage is given by f(x) = 120 - 25x. This means, initially the ship is 120 miles away from its destination.

If the ship traveled 120 miles, then f(x)=0 (the ship will be 0 miles away from its destination) and

0 = 120 - 25x

25x = 120

x = 4.8 hours.

Submarine:

At x = 0 hours the submarine was 75 miles away

At x = 5 hours, the submarine was 0 miles away.

So, in 5 hours the submarine traveled 75 miles

Which expression is equivalent to 1/2x+(−7)−2 1/4x−(−2

Lynna [10]

The equivalent expression to the given expression is $\mathbf{=-(\dfrac{7}{4}x+5)}$

<h3>What is an algebraic expression?</h3>

Algebraic expressions are mathematical expressions. They usually consist of one or more variables with their coefficients and arithmetic operators such as: (division, multiplication, addition, and subtraction).

From the given expression, we are to determine an expression that is equivalent to:

$=\dfrac{1}{2}x + (-7) -2 \dfrac{1}{4}x -(-2)$

To do this, we are going to simplify the above-given expression to its lowest term since we are not given any options to choose equivalent expressions from.

By doing so, we have:

$=\dfrac{1}{2}x -7 -\dfrac{9}{4}x +2$
