Answer:
Since x is an exponent, y = 15 × 8ˣ represents an exponential function.
It is about 6.24 so it rounds to 6
U=2x+3, x=u/2-3/2
u^2+8u+11=0
u1=(-8+sqrt(64-44))/2=-4+sqrt(5)
u2=-4-sqrt(5)
x1=u1/2-3/2=-7/2+sqrt(5)/2
x2=u2-3/2=-7/2-sqrt(5)/2
Answer:
27 years
Step-by-step explanation:
21 × 2 = 42
42 - 15 = 27
The answer is 40. Hope this helped! Between 8 and 10, you can determine the least common multiple by multiplying. 8*5=40, and 10*4=40.
