There are 1000 Times more people on earth right now than there was in 4,000 BCE. It's just 7billion divided by 7million.
Answer:
-18
Step-by-step explanation:
Left Hand Side = -2(7a + 9b) = -14a - 18b
Comparing it with Right Hand Side, ? = -18
Answer:
g(x) = 
Step-by-step explanation:
From the picture attached,
Given function is,
f(x) = x + 1
We have to find the value of g(x) if the composite function has been given as,
f[g(x)] = g(x) + 1 = 
g(x) = 
= 
= 
Therefore, g(x) = will be the answer.
Let s = northbound train
Then
2s = southbound train
:
Distance = time * speed
4s + 4(2s) = 600
:
4s + 8s = 600
:
12s = 600
:
s = 600/12
:
s = 50 mph is the northbound train
Then
2(50) = 100 mph is the southbound train
:
:
Check:
4(50) + 4(100) = 600
-3x^2-2x (+-)6=0
ax^2+bx+c
a=-3
b=-2
c= either positive or negative 6 (there is no plus or minus in your question.)
What are the answer choices? It might help.
