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
5+2=7 which means there will be 7 zeros so it is 10000000 times greater than
3 - x = 10
-x = 10 - 3
-x = 7
x = -7 <===
Answer:
7
Step-by-step explanation:
135 = 15*(x+2)
Can the numbers be repeted!!!!!!!!!!!!!!!!!!!!!!!!!
