Answer:
62.8318530718
Step-by-step explanation:
Answer: 56
y =0
From the equation;
8³ × 8⁻⁵×8^y = 8⁻²= 1/8²
From the laws of indices;
aⁿ×aⁿ = a^2n
Therefore;
8³ × 8⁻⁵×8^y = 8^(3+-5+y)
8^(-2+y) = 8^-2 ; but the bases are the same and thus the exponents are the same;
-2 + y = -2
y = 0
y-intercept = 9 → (0, 9)
x-intercept = -7 → (-7, 0)
Look at the picture.
