Answer:
i have done the cutting of x's exponent
Step-by-step explanation:
= 3x - 30+9 =0
= 3x - 21 =0
= 3x= 21
= x = 21/3
x= 7 this the answer
Answer:
25
Step-by-step explanation:
If it gives a result of -4 then our equation will have .... = -4
If we subtract 9 from the quotient of a number and 5 we have x/5 - 9
Our equation is:
x/5 - 9 = -4 add 9 to both sides
x/5 = -4 + 9
x/5 = 5 multiply both sides by 5
x = 5(5)
x = 25
Check: 25/5 - 9 = 5-9 = -4
Answer checks as correct from information given
Answer:
slope is -2/5, y intercept is (0,5)
Step-by-step explanation:
The slope is the number in front of the x, or how steep the line is on the graph. In this case, it is -2/5.
The y intercept happens when x = 0, so if you make x = 0 in this equation, you find that you are left with y = 5. That gives you the point (0,5) as your y intercept.
Answer:
The answer to your question is 8649 persons
Step-by-step explanation:
Data
Equation y = 11.89x - 15345.2
Year = x = 2018
Process
1.- Just substitute x in the equation
y = 11.89 (2018) - 15345.2
2.- Multiply 11.89 by 2018
y = 23994.02 - 15345.2
3.- Subtract to find x
y = 8648.82
4.- Conclusion
There was 8649 persons in 2018.
