Answer:
y=4/5x+3
Step-by-step explanation:
1. 1/a^8 (Sorry I can't find out what the others are)
Answer:
1. b=√56
Step-by-step explanation:
1. Pythagorean therom states a²+b²=c² and in number 1 we are given the c or the hypotenuse so plugging in the values we know 13²+b²=15²
which equals 169+b²=225 subtract 169 from both sides and we get b²=56
square root both sides and we get b=√56
The value of x is 
Explanation:
The expression is
Adding
to both sides of the equation, we get,

Using log definition, if
then
, we have,

Using exponent rule,
,

Simplifying, we have,

Dividing both sides by 9, we have,

Simplifying,

Thus, the value of x is 
I believe 62 because it it’s closer to an hour
