Well, 3=2x+10, so that means -7=2x , to solve for x I will just divide, so x= -3.5
Honestly this makes no logical sense but you should take 43,118+6,549=49,667
The regression equation to predict the number of cans sold on a day that is 90°F will be 871.
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
A convenience store manager notices that sales of soft drinks are higher on hotter days, so he assembles the data in the table, shown above. Use technology to find the equation of the least-squares regression line.
Then the regression line will be passing through (55, 340) and (84, 780). Then we have
y - 340 = 15.17(x - 55)
Then the regression equation to predict the number of cans sold on a day that is 90°F will be
y - 340 = 15.17 (90 - 55)
y = 871

What are the options? But I think a good estimate is $700.
