Answer:
x = 19.325
Step-by-step explanation:
You have: x - 4.225 = 15.1
Isolate x by adding 4.225 to both sides
x - 4.225 + 4.225 = 15.1 + 4.225
x = 15.1 + 4.225 = 19.325
x = 19.325
3(6x+2) <9
Use distributive property:
18x + 6 < 9
Subtract 6 from both sides
18x < 3
Divide both sides by 18
X < 3/18
Simplify:
X < 1/6
First, remove the parentheses
-7+2x+7=-7
Cancel the equal terms.
2x+7=0
Subtract 7
2x= -7
Divide both sides by 2
Final answer is:
X= -3.5
There are 1000 Times more people on earth right now than there was in 4,000 BCE. It's just 7billion divided by 7million.
Looking at the data it looks like a line. So the answer will be in y+mx+b format.
Knowing it is a line eliminates answers b and c.
looking at options a is says it starts at about .1 when x is zero. We can see this looks pretty close as the left-most dot is below 1 already.
The slope on a is 1/2--> increasing 1 vertically for every 2 horizontally. The pattern mostly follows that rule.
Therefore a (y=1/2x+.1) would be the correct answer
