Answer:
y = 112
Step-by-step explanation:
If y varies directly as the square of x
mathematically;
y ∝ x²
y = kx² where 'k' is the constant of proportionality
let u know the value of k for this equation by making k the subject of the formular from y = kx²
divide both sides by x²
k = y / x²
given that y = 567 x = 9
k = 567/(9)²
k = 567/81
k = 7
now to get the value of y when x = 4
from the equation conneting x, y,
y = kx²
y = 7 × (4)²
y = 7 × 16
y = 112
Answer:
the answer is 9
Step-by-step explanation:
Let n be the amount of points earned in round 5
the goal of the game is to get zero when you add up the point value from all the rounds.
this means
-9 +3 + (-8)+ 2 +n =0
add up all the given numbers, then see which number(n) is required in order to get zero
