Answer:
I may be wrong, but I learned that the first slot would be "terms". 4:3 would be an example of a ratio so it couldn't be ratio and a difference is subtracting.
The second slot would not be a geometric sequence because it is not correctly placed on the number line.
Therefore, the answers would be "terms" and "is not"
We have that
<span>x - y = 4-------> multiply by -1-----> -x+y=-4-----> equation 1
x+ 2y = 4------> equation 2
add equation 1 and equation 2
-x+y=-4
x+2y=4
-----------------
0+3y=0-----> y=0
x+2y=4------> x+0=4------>x=4
the solution is the point (4,0)</span>
Well, we want to find how much it would cost for 1 gallon, the easiest way to do that is subtract 21 from 18.
21 - 18 = 3
So, it's 3 dollars per gallon. Now that we know that we multiply it by 8 to find how much it would cost.
8 x 3 = 24
Eight gallons of gas would cost 24$ :D
Answer:
9
Step-by-step explanation:
3² = 3 x 3 = 9
