You already know that y equals -4. It says that x equals 3, so multiply the -4 by 3 and because it has a negative number and a positive number it will equal -12. Remember anytime you see a letter after a number it means multiply. The complete problem should be -10 because 2 is a whole number you subtract it from -12. Hope that helped you out some.
Answer:
-914
Step-by-step explanation:
f(n)=-5f(n-1)-n
f(2)= -5f(1) -2 = -5(7) - 2 = -37
f(3) = -5f(2) - 3 = -5(-37) - 3 = 182
f(4) = -5f(3) - 4 = -5(182) - 4 = -914
Answer:
4/57
Step-by-step explanation:
Prob=DC/SS
=4/53+4
=4/57
Answer:
(-2, 8) and (5, -1)
slope: (y² - y¹) / (x² - x¹)
(-1 - 8) / (5 + 2) = -9/7
y = -9/7x + b
8 = -9/7(-2) + b
8 = 18/7 + b
8 = (2.57) + b
b = 5.43
y = -9/7x + 5.43
parallel = same slope
y = -9/7x
perpendicular = reciprocated slope
y = 7/9x
