Solve the inequality: 9-4 r > 5

a. r > 1
b. r < - 4
c. r < 1
d. r < - 1

u what ?

step-by-step explanation:

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

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

yes   because as the functions are graphed they eventually will intersect unless otherwise
