(2,3). The vertex of a parabola is the highest or lowest point of the graph
Answer:
D: (0, 8) and (8, 8)
Step-by-step explanation:
Line y = 8. So doesn't matter what x values are, y is always equal 8
Answer
D: (0, 8) and (8, 8)
The value of x is 8 when y = 12 if variables x and y have proportional relationship.
According to the given question.
Variables y and x have proportional relationship.
⇒ y ∝ x
Let k be the constant of proportionality.
⇒ y = kx
Also, it is given that
y = 21 when x = 14
Substitute the value of y = 21 and x = 14 in y = kx to find the value of k.
21 = k(14)
⇒ k = 21/14
⇒ k = 3/2
Therefore, the value of x when y = 12
y = kx
⇒ 12 = (3/2)x
⇒ 12 × 2 = 3x
⇒ 24 = 3x
⇒ x = 24/3
⇒ x = 8
Hence, the value of x is 8 when y = 12.

Answer:
y= 3cb/ 5t
Step-by-step explanation:
combine 5 and t/4
5t/4 times y= 3(b/4) times c
combine 5t/4 and y
5ty/4=3(b/4) times c
combine 3 and b/4
5ty/4= 3b/4 times c
combine 3b/4 and c
5ty/4=3bc/4
multiply each term in 5ty/4=3bc/4 by 4/5t to eliminate the fractions
y=3bc/4 times 4/5t
simplify
y=3cb/5t
