Answer: (43) 16
(44) y = -(9/4)x = 6
(45) parallel: y = 2x - 4
perpendicular: y = -(1/2)x - 5/2
<u>Step-by-step explanation:</u>
43) f(x) = (1/3)x + 8
f(-12) = (1/3)(-12) + 8
= -4 + 8
= 4
3f(-12) = 3(4)
= 12
3f(-12) + 4 = 12 + 4
= 16
44) slope (m) =
45) parallel is same slope → m = 2
perpendicular is opposite reciprocal slope →
parallel
perpendicular
Answer:
relationship between hypotenuse and perpendicular is given by sin angle
sin60=p/h
√3/2=a/16
√3/2×16=a
8√3=a
option C is your answer
Sylvia is correct. This is because the sum of angles in a triangle is 180° and a triangle has 3 angles. If it had 2 right angles (90° each) it would already equal 180° and that's not possible because a thrid angle has to exist.
Hope I helped!
