7. The table below shows values of two continuous linear functions, �(�) and �(�). Unfortunately, the printer smudged a few of the values in the table.

Given the above information, what is the value of �(�) when �(� + 10) = 20?

A 17

B 20

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
