Step-by-step explanation:
3x + y = 9
3x − 5y = 15
Solve with elimination. Subtract the second equation from the first.
6y = -6
y = -1
Plug into either equation to find x.
3x + -1 = 9
3x = 10
x = 10/3
Answer is answer
Step-by-step explanation:The number of newly reported crime cases in a county in New York State is shown in
the accompanying table, where x represents the number of years since 2007, and y
represents number of new cases. Write the linear regression equation that represents
this set of data, rounding all coefficients to the nearest hundredth. Using this
equation, find the projected number of new cases for 2016, rounded to the nearest
whole number

Answer:
Step-by-step explanation:
First off, you need to add up AB and BC. You would get the equation:
2(3x-4)=62, since there are two segments. Solve it/simplfy.
6x-8=62 => 6x=70 => x= 11.66666(forever)
Since you alreday solved one, you easily know the answer is c.
