8:15 is the answer assuming the clock is at PM.
Answer:
D
Step-by-step explanation:
To obtain f(g(x)) substitute x = g(x) into f(x), that is
f(10 - 5x)
= (10 - 5x)² + 5 ← expand (10 - 5x)²
= 100 - 50x - 50x + 25x² + 5 ← collect like terms
= 25x² - 100x + 105 → D
C because 180-230 would be negative b as well as three quarters of seven
Answer:
37.2 mph
Step-by-step explanation:
They are going 0.60 times the speed that converts to 62 mph. Their speed is approximately ...
0.60 × 62 mph = 37.2 mph
2+(-3) = -1
2- 3 = -1
-1=-1
The question is why though ?
It is because you keep the negative exponent which is with the biggest number. So this is how its look like +2 -3, so 3 is bigger then 2 so for that reason you keep the negative sign.
I hope that's help:)
