ikadub [295]3 years ago
8 0

Answer:

y=-2x-12

Step-by-step explanation:

Make the equation into slope intercept form

-2y=-4x-12

divide by -2

y=2x+6

since the line is parallel the slope is the same

y=2x+b

plug in (4,-4)

-4=8+b

b=-12

y=-2x-12

The top of a mountain is 2,450 feet above sea level a shipwreck was discover 310 feet below sea level what is the distance betwe
arlik [135]

Answer:

d=2,760\ ft

Step-by-step explanation:

Let

x ----> the height of the top of a mountain above sea level

y ----> the deep of a shipwreck below the sea level

we know that

The sea level represent the height equal to zero

In this problem we have

x=2,450\ ft ---> is positive because is above sea level

y=-310\ ft ---> is negative because is below sea level

To find out the distance between the mountain top and the ship wreck, determine the absolute value of the difference between the two values

d=\left|x-y\right|

substitute the values

d=\left|2,450-(-310)\right|

d=\left|2,450+310\right|

d=\left|2,760\right|

d=2,760\ ft

The length of a rectangle is 6 more than twice its width. The
Whitepunk [10]

Answer:

The answer is option (C). The width of the rectangle=6 inches

Step-by-step explanation:

<em>Step 1: Determine the dimensions of the rectangle</em>

width=w

length=w+6

<em>Step 2: Determine the perimeter of the rectangle</em>

P=2(L+W)

where;

P=perimeter

L=length

W=width

In our case;

P=36 inches

L=w+6

w=w

replacing;

2(w+w+6)=36

2(2 w+6)=36

4 w+12=36

4 w=36-12=24

4 w=24

w=24/4=6

W=6 inches

L=6+6=12 inches

The width of the rectangle=6 inches

A teacher writes a simple computer program where she can type students name and computer tells her the students birthday.
Vikki [24]

Considering that each student has only one birthday, each input will be related to only one output, hence this relation is a function.

<h3>When does a relation represent a function?</h3>

A relation represents a function when each value of the input is mapped to only one value of the output.

For this problem, we have that:

  • The input is the student's name.
  • The output is the student's birthday.

Each student has only one birthday, hence each input will be related to only one output, hence this relation is a function.
