Pre-cal I don’t understand much

33

Step-by-step explanation:

f(x) = 4x-3

Let x= 9

f(9) = 4*9 -3

     36-3

     33

Step-by-step explanation:

f(x) = 4x - 3

f(x) = 9

Substituting.

9 = 4x - 3

Adding 3 to both sides.

12 = 4x

Dividing both sides by 4.

3 = x

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

well, you see here, jamal was born to 2 parents, his mother who he lives with and his father who left at a young age and who happens to be younger than him. he stole cookies because he has to steal food due to the fact that he spends his government poverty checks on pot and women.
