Answer:
x = 3
Step-by-step explanation:
(4/5)^x = 64/125 means that 4^x / 5^x = 64/125
x can only be 3 because 4^3 = 64 and 5^3 = 125
Please mark Brainliest :)
Y - y1 = m(x - x1)
m = -2 (1, -5)
y - (-5) = -2(x - (-5)
y + 5 = -2(x + 5)
y + 5 = -2x - 10
y = -2x - 15 <<< answer
hope this helps, God bless!
From information given, we know
208 miles was at rate of 65 mph. so divide total mileage by speed to get time spent.
208 ÷ 65 = 3.2 hours
So the rest of the trip took 6 - 3.2 = 2.8hours to travel another 348 total miles minus the 208 miles driven at 65mph is 140 miles.
140 miles divided by 2.8 hours gives speed
140 ÷ 2.8 = 50 miles per hour
Um I think it is 2,1 count over 2 then go up1
50 miles apart
if 1 = 10 then 5 = 50 using the tens rule
