Answer: 130
Step-by-step explanation:
Find the height of the triangle by using the pythagorean theorem
So the height is sqrt(100 - 25) = 5sqrt(3)
The area of the triangle is 30 * 5sqrt(3) / 2 = 75sqrt(3) = 129.9 = 130

Answer:
A coefficient number is a number multiplied by a variable.
Step-by-step explanation:
Answer:
D) -3
Step-by-step explanation:
Slope of a linear function:
The slope of a linear function is the amount by which y changes when x increases by 1.
In this question:
When x = 1, y = 12
When x = 2, y = 9
When x = 3, y = 6
When x = 4, y = 3
So each time x increases by 1, y decreases by 3, which means that the slope is -3, and the answer is given by option D.
