X^2^4 = x^8
Just multiply then 2 and 4 to get 8
Let's do the math, 2.5+2.5+2.5+2.5( 4times) is 10hrs+2.5= 12.5hrs
Answer: 42
Step-by-step explanation
Switch x out with 3
using Pemdas do the exponent first
3^2 is 9
then multiply
5*9= 45
then subtract
45-3=42
Plug the values into point slope and simplify
y-4= 4(x-(-2))
y-4= 4x+8
y= 4x+12
Final answer: y=4x+12
