Answer:
Step-by-step explanation:
<u>Given vertices of triangle:</u>
- A(1, 2), B(3, 4), C(5, 0)
<u>The centroid is found as the average of x- and y- coordinates of three vertices:</u>
- C = ((x₁ + x₂ + x₃)/3, (y₁ + y₂ + y₃)/3)
<u>Substitute the coordinates into formula:</u>
- C = ((1 + 3 + 5)/3, (2 + 4 + 0)/3) = (3, 2)
Correct choice is B
Answer:
B
Step-by-step explanation:
First distribute the 2x to get:
4x² + 10x
Then distribute the -5 to get:
-10x - 25
Then combine
4x² + 10x - 10x - 25
The 10x's will cancel leaving you:
4x² - 25
Answer:
y=5*3^x
Step-by-step explanation:
y=5*3^(-1) =5/3
y=5*3^0=5*1=5
y=5*3^1=5*3=15
