1.3+-2.4= -1.1 hope I helped :)
It would be answer A because something in the negatives can not be greater than something in the negatives
Answer:
The price for one cone before tax is $2.26.
Step-by-step explanation:
The tax for each cone is $.17
Ronnie buys six cones. The total tax for the cones is 6 X $.17 = $1.02
Next, we subtract the total taxes from the total price $14.58 - $1.02 = $13.56
So Ronnie owed $13.56 for the six cones BEFORE taxes. We takes this amount and divide it by six to get the cost for one cone.
$13.56 / 6 = $2.26 per cone.
Check our work
Purchase one cone for $2.26 plus $.17 cents tax = $2.43 total cost per cone.
6 cones at $2.43 each would be 6 X $2.43 = $14.58.
This matches the total bill from the story problem.

41 squared (1681) minus 9 squared (81) is 1600. 40 is the square root of 1600.
Answer:
x = -5.6
Step-by-step explanation:
Using the given coordinates in the given slope formula, we have ...
(y2 -y1)/(x2 -x1) = -8/5 . . . . . using the given slope
<h3>Setup</h3>
(4 -x)/(3 -9) = -8/5 . . . . substituting (9, x) for (x1, y1) and (3, 4) for (x2, y2)
<h3>Solution</h3>
Multiplying by 30, we have ...
5(x-4) = -48
5x -20 = -48 . . . . eliminate parentheses
5x = -28 . . . . . . . . add 20
x = -5.6 . . . . . . . . divide by 5

<em>Additional comment</em>
In the attachment, we have written the point-slope equation of the line, then found the point on that line that has a x-coordinate of 9. We see the y-coordinate of that point is -5.6, as computed above.
If you swap the points (x1, y1) and (x2, y2), then the slope equation ends up with fewer minus signs to handle.
