Answer:
Step-by-step explanation:
The shop sold 70 ice cream cones. It means that x + y = 70Small cones cost 3.95 and large cones cost 5.75. The total sales made from the selling 70 ice creams is $370.10. It means that 3.95x + 5.75y = 370.1 - - - - - - - - - -1Substituting x = 70 - y into equation 1, it becomes3.95(70 - y) + 5.75y = 370.1276.5 - 3.95y + 5.75y = 370.1- 3.95y + 5.75y = 370.1 - 276.51.8y = 93.6y = 93.6/1.8y = 52x = 70 - 52x = 18

The equation of the line passing through the points (2,-1) and (4,5) is 3x-y = 5
Step-by-step explanation:
Given:
Points are (2,-1) and (4,5)
To find the equation of the passing through the given points.
Formula
The equation of the line passing through () and () is
Now, putting,
we get,
or,
or, 2(y+1) = 6(x- 2)
or, y+1 = 3(x-2)
or, 3x-y=5
