Answer:
i'll answer the question after you clarify for me, if f(x) =-2x +3
then f (this is what you need to clarify for me please, theres 2 end parenthesis, but no start parenthesis and 2 numbers and 2 equal signs. what needs solved?)

Answer:
200 N/m
Step-by-step explanation:
Rearranging the formula F = kx, you find that k = F/x. For the first spring,
F = 36 N and x = 0.06 m (6 cm). So the spring constant, F/x, is 36N/0.06m = 600 N/m
For the second spring, F = 36 N and x = 0.09 m. F/x = 36N/0.09m = 400 N/m
The difference between these values is 200 N/m, and that's the answer.
I believe it is:
(−16/9, 1/9)
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
843
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 24 and d = - 7 - (- 24) = - 7 + 24 = 17, thus
= - 24 + (51 × 17) = - 24 + 867 = 843
Answer:
13
Step-by-step explanation:
7 packs x 5 cards in each pack given away = 35
there were 56 cards left
56 + 35 = 91 total cards
91 / 7 = 13 cards in each pack
