Which relation is a direct variation that contains the ordered pair (2, 7)?
Tasya [4]
Lets write equation of a function:

y = kx + n

Direct variation in simple is equation of a line which has n=0 or in other words which y to x ratio is k.

First option gets 7=7 but it isnt direct variation because n is not equal to 0

third option is indeed correct. once we implement coordinates (2,7) we get 7=7

Answer is 
y = 7/2x

Graph y=6x−7<br> Identify the x-intercept.
valina [46]

9514 1404 393

Answer:

  x-intercept: 7/6

Step-by-step explanation:

The x-intercept is found by solving for x when y=0.

  0 = 6x -7

  7 = 6x . . . . . add 7 to both sides of the equation

  7/6 = x . . . . divide both sides by 6

The x-intercept is 7/6 = 1 1/6 ≈ 1.167.

__

The y-intercept is the constant in the given equation: -7. The slope of 6 tells you the line rises 6 units for 1 unit to the right. So, the point (1, -1) is another point on the graph. The line through those two points, (0, -7) and (1, -1), will intersect the x-axis at x=7/6.

What is the selling price of an item if the original cost is $784.50 and the markup on the item is 6.5 percent?
JulijaS [17]

Answer:

Solution:

Given, cost price = $784.50

Profit = 6.5% of cost price

        = 6.5/100 × $784.50

        = $50.9925 [since, profit% is always on C.P.]

And selling price = cost price + profit

                      = $784.50 + $50.9925

                      = $835.4925

Hence, selling price = $835.4925
