Y = 5.5x is a linear equation (i.e. the highest power of the variables is 1). Therefore, the line will be a straight line with a slope of 5.5
75.6%
78 - 19 = 59
59 / 78 = .75641
.75641 x 100 = 75.641
The percentage that the store has taken off would be 30%.
Answer:
x = 4/5
Step-by-step explanation:
The x-intercept looks like (x, 0); the coordinate 0 indicates that the point lies on the x-axis. If we start with 4/5x + 1/3 y= 1 and let y = 0, we will get an equation for the x-intercept:
(4/5)x + (1/3)(0) =1
Then 4/5x = 1, and (5/4)(4/5)x = (1)(4/5).
Thus, x = 4/5, and the x-intercept is (4/5, 0).

Cross multiply.
5.4x=9*25.8
5.4x=232.2 Divide both sides by 5.4
x=43
