Decide whether the relation defines a function.
diamong [38]

Answer:

A

Step-by-step explanation:

Lets first solve the relation for "y". Shown below:

3x=9-4y\\4y=-3x+9\\y=-\frac{3}{4}x+\frac{9}{4}

This is clearly an equation of a line in the form  y=mx+c

It will be a negatively sloped line, when graphed.

We can use vertical line test to determine function or relation. If a vertical line passes through only 1 point in the graph, we say that it is a function.

Think of a negatively sloped line. No matter where you draw a vertical line, it will only cut the line at 1 point.

So, this is definitely an equation of a function

Correct answer is A

A rectangular swimming pool measures 14 feet by 30 feet. The pool is
Zolol [24]

Answer:

The total cost of resurface the path is \$600

Step-by-step explanation:

step 1

Find the area of the path

The area of the path is equal to the area of the path plus the swimming pool minus the area of the swimming pool

A=(14+3+3)(30+3+3)-(14)(30)

A=(20)(36)-(14)(30)

A=300\ ft^{2}

step 2

Find the cost of resurface the path

Multiply the area of the path by $2 per square foot

300*2=\$600
