Taking algebra (9th grade) pls helpp

f(n) = -7+3n

Step-by-step explanation:

I plugged the values into the equation and they work.

f(n) = -7 + 3(10) = 27

f(n) = -7 + 3(12) = 26

f(n) = -7 + 3(16)= 32

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
