Answer:
Step-by-step explanation:
Let x represent his average walking speed.
If the average speed on the bike is 8 mph faster than his walking speed,it means that his biking speed is (x + 8) mph
Distance = speed × time
Alex returns a bike to a friends house from his own house in 1/2 hour. This means that the distance covered is
0.5(x + 8)
He walks back over the same route in 1.5 hours. This means that the distance covered is
1.5x
Since the distance covered is the same, then
1.5x = 0.5(x + 8)
1.5x = 0.5x + 4
1.5x - 0.5x = 4
x = 4 mph
Therefore, the distanceof Alex's house from his friend's house is
4 × 1.5 = 6 miles

Answer: 3log5(2) - 1 or ~0,29203
Step-by-step explanation:
2log5(4) - log5(10)
log5(4^2) - log5(10)
log5(4^2/10)
log5(16/10)
log5(8/5)
Log5(8) - log5(5)
log5(2^3) - 1

Answer:
(2, - 3 )
Step-by-step explanation:
Given the 2 equations
y = - 3x + 3 → (2)
y = - 9x + 15 → (2)
Substitute y = - 3x + 3 into (2)
- 3x + 3 = - 9x + 15 ( add 9x to both sides )
6x + 3 = 15 ( subtract 3 from both sides )
6x = 12 ( divide both sides by 6 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (1)
y = - 3(2) + 3 = - 6 + 3 = - 3
solution is (2, - 3 )
