Answer:


Step-by-step explanation:
Given
Let x represent years and V represents the value.
So, we have:


Solving (a): The linear function
First, we calculate the slope (m)

This gives:



The linear function is calculated using:

Where:


So, we have:

Open bracket


Make v the subject


So, the function is:

Solving (b): When x = 8
Substitute 8 for x in 



Take LCM




<em>Hence, its value after 8 years is 1313.3</em>
Answer:
(A) 10
Step-by-step explanation:
Let age of Marco's be "x" years
then according to question
Yolanda age will be "2x - 5"
Also in the question it is given that age Yolanda is 15 years.
then, 2x - 5 = 15
Adding 5 both sides of the equation, we will get
2x = 20
Dividing both sides of the equality by 2, we get
x = 10
therefore, Age of Marcus will be 10years
Option (A) is the correct option.
Given:
Rectangle: 320 x 190
triangle: base: 305
I'm assuming that the unit measure is in miles.
I found a map of Nevada and I figured that the length of the rectangle is serving as the height of the triangle.
Area of the rectangle = Length * width
A = 320 mi x 190 mi
A = 60,800 sq. mi.
Area of a triangle = (height * base) / 2
A = (320 mi x 305 mi) / 2
A = 97,600 sq. mi / 2
A = 48,800 sq. mi.
Total Area = 60,800 + 48,800 = 109,600 square miles.
Answer:
Step-by-step explanation:
m = 5 ; (3, -4)
y - y₁ = m (x - x₁)
y - [-4] = 5 (x - 3)
y + 4 = 5x - 15
y = 5x - 15 - 4
y = 5x - 19
