Identify the x- and y-intercepts for x = 3.
1 answer:
Answer:
D: x-int : (3, 0); y-int : None
Step-by-step explanation:
The concept is:
- The x-intercept is any point on the graph where the value of y is equal to 0.
- And, y-intercept is any point, where the value of x is equal to 0.
- Now, For the equation, x = 3, the x-intercept = 3 and the y - intercept = 0
- The graph of x = 3 is attached.
Hence, the correct answer is D: x-int : (3, 0); y-int : None

Given:
Point G is the centroid of triangle ABC.
FG = x + 8 and AG = 6x - 4
To find:
The value of the variable x.
Solution:
Using rule of centroid:
Multiply by 3 on both sides, we get
⇒ 3(6x - 4) = 2(7x + 4)
⇒ 18x - 12 = 14x + 8
Subtract 14x from both sides.
⇒ 4x - 12 = 8
Add 12 on both sides.
⇒ 4x = 20
Divide by 4 on both sides.
⇒ x = 5
The value of x is 5.
