$7865 put 5 in for t times 411 is 2055 + 5810
Answer:
f(x) = - 2x - 1
Step-by-step explanation:
Let the linear function f(x) is given by f(x) = ax + b where a and b are unknown constants.
Given that f(0) = -1 and f(2) = -5
Hence, a(0) + b = - 1, ⇒ b = - 1
Again from the condition given
a(2) + b = -5, ⇒ 2a - 1 = - 5, ⇒ 2a = - 4, ⇒ a = - 2.
Therefore, the linear function is f(x) = - 2x - 1 (Answer)
The side length has to be between 2 (=9-7) and 16 (=9+7). In both these corner cases the triangle will have collapsed to a line.
So the correct answers are B,C,D and E, and F is a corner case. Theoretically I suppose you have to count F in as a valid answer.
Answer:
B.
Step-by-step explanation:
y = x^2 - x - 12
y = (x-4)×(x+3) that means x it either 4 or -3
y = x + 3
for x = 4 ➡ y = 3+4 ➡7
for x = -3 ➡ y = -3 + 3➡0
(the answer key is most probably faulty there's no way for y to be 0 in both scenarios)
