By instead of the ax "a number" v a variable favor x, friend can acquire the equation 7x - x = -48. Then, additional simplify the equation by combining favor terms to equal 6x = -48. After that, divide both sides by six to obtain x alone, making your last ptcouncil.net x = -8.Hope this help :)
Lucas scored 9 goals in 4 soccer games last season. Roughly how plenty of points go Lucas typical per game?
It can be found by integral.
You are watching: Seven times a number minus the number is -48. find the number.
First let"s discover the intersection points.
Only intersection allude is x = 2.
And that is request to find the area in the interval (2, 4).

We will usage integration through parts.
Looking in ~ the graph, we"ll notice that there is a neighborhood maximum at x=0 and it looks similar on both sides of the y axis, because of this making it symmetric about the y axis provided the options
see the attached figure to much better understand the problem
we recognize that
Triangles JKL and also MNP are similar by AA Similarity Theorem
If two numbers are comparable then the proportion of its equivalent sides is proportional
substitute the provided values
solve for x
