Answer: C
Step-by-step explanation:
Given
Nancy bought the bag with 1100 beads to make necklaces
She found another bag with 700 beads
So, the total number of beads is the sum of two i.e. 1800 beads
It takes 50 beads per necklace
The number of necklaces that can be formed is
Answer: Option D: R = {3, 9, 12}
Step-by-step explanation:
The range of a function is the set of the possible outputs of a function:
if we have the function f(x) = y, the values of x are the domain, and the values of y are the range.
In the image, the set at the right is the output, so the set in the right is the range.
such that we have the pairs (-2,3) (2, 3) (3, 9) (4, 12)
So the range will be R = {3, 9, 12}

======================================================
Explanation:
The piecewise function f(x) changes based on what the input is.
We have two cases:
- Case A) if x > 4, then f(x) = 3x-1
- Case B) If , then f(x) = 2x
The input x = -3 satisfies the inequality , so we go with case B for this input
f(x) = 2x
f(-3) = 2(-3)
f(-3) = -6
In contrast, the input x = 7 satisfies the inequality x > 4. So we go for case A this time.
f(x) = 3x-1
f(7) = 3(7)-1
f(7) = 21-1
f(7) = 20
----------------------
Side note: It might be better to let g(x) = 3x-1 and h(x) = 2x. Then we could further say "If x > 4, then f(x) = g(x) OR if , then f(x) = h(x)". Though this might be a more wordy definition.
