The answer is 3x.
Step-by-step explanation:
I used a calculator
Answer:1,875
Step-by-step explanation:15,000 ÷ 8 = 1,875
1. The information given in the problem is:
- <span>Each arrangement uses 1 vase and 11 orchids.
- </span><span>Each case cost Marco $4.00.
</span> - C: the <span>total cost of the arrangement.
- r: </span><span>the cost of 1 orchid.
2. Therefore, you must multiply the cost of 1 orchid by the 11 orchids that he uses in e</span><span>ach arrangement,</span><span> and then, you must add the cost of 1 vase, as below:
C=11r+4
3. Finally, you can conclude that the</span> correct answer is the last option:
D)C=11r+4
X=5, for the first one
Y= -9 for the second one
Just substitute the ordered pairs in the equation of y = x²+k
(3,-2)
-2=9+k
k= -11
Therefore, the value of k is - 11
