Shelma has an 80 in her math class and plans to increase her grade 5 percent per week. darian also has an 80, but plans to increase his grade 10 percent every 2 weeks. how many weeks before both shelma and darian have the same grade?

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

9 x 8 divided by (5-3)=36

47 - 90 = 43

43 - 180 = x

x = 137

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
