Formula

The area of any triangle is

A = 1/2 * b * h


Givens

A = 10

b = 4

h = x + 3


Sub and solve

10 = 1/2 * 4 * (x + 3) Take 1/2 of 4

10 = 2 * (x + 3) Divide by 2

10/2 = 2( x + 3) / 2

5 = x + 3 Subtract 3 from both sides.

5 - 3 = x + 3 - 3

2 = x <<<<<<<<<<<<<< answer.

A = 1/2 b h where A = 10 b = 4 and h = x + 3

so

h = 2A/b

h = 2*10 / 4

h = 20/4

h = 5


h = x + 3

5 = x + 3

x = 2


Answer

x = 2

Ganezh [65]

Answer:

Y = 300 + 2X

Y( in dollars)

It is a functional relationship because a change in the value of X results in a corresponding change in the value of Y. And does not involve any uncertainty.

Step-by-step explanation:

Given:

Annual fixed due = $300

Variable cost = $2 per visit

X = number of visits in a year

Y = total yearly cost.

Y = annual cost + variable cost

Y = $300 + $2×X

Y = 300 + 2X

Y( in dollars)

It is a functional relationship because a change in the value of X results in a corresponding change in the value of Y. And does not involve any uncertainty.
