Use sum and difference formulas, where difference is positive.
Larger number = (sum+difference)/2 = (54+10)/2 = 32
Smaller number = (sum-difference)/2 = (54-10)/2 = 22
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
6x + x = 49
7x=49
x=7
Substitution:
6x=6X7=42
