Answer:
x=9 y=-4
Step-by-step explanation:
1) to eliminate a variable make sure they are the same so you can cancel them out
lets eliminate x
-3 and -2 share a GCF of 6 so
2(-3x-4y=-11)
-6x-8y=-22
3(-2x-6y=6)
-6x-18y=18
-6x-8y=-22
-
-6x-18y=18
--------------------------
10y=-40
y=-4
2)substitute y as -4 in the second equation
-2x-6(-4)=6
-2x+24=6
-2x=-18
x=9
Answer: 7.33980582 x 10^0
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. The sign of the exponent will depend on the direction you are moving the decimal.

On the left side, the graph is going closer to 0, that explains the first coordinate 0. On the right side, the graph approaches positive infinity, so that explains the infinity. I hope this helps!
Answer:
Population of bacteria at time 
is 
Step-by-step explanation:
The complete question is
If 
represents the number of bacteria in a culture at time t, how many will there be at time
Solution
Given
The population of bacteria after time t is equal to
Population when at time
We will substitute the value of time in above equation.
115% of the price is 270,25
115*x/100=270,25
x=270,25*100/115
x=235 $ is the price
270,25-235= 35,25 $ is the tax
