Answer:
<u>The correct answer is </u>
<u>C. k+d=130
</u>
<u>7k = 3d</u>
<u>Number of kids Dr. Irvine see in a week is 39.</u>
Step-by-step explanation:
1. Let's review the information given to answer the question correctly:
Number of patients Dr. Irvine see in a week = 130
Radio of kids to adults = 3:7 or 3/7
Number of Kids = k
Number of adults = d
2. Let's find the equations system that should be set up to find out how many kids Dr. Irvine see
k + d = 130 (Number of patients Dr. Irvine see in a week)
Including the ratio:
7k = 3d
Replacing d:
d = 130 - k
Now substituting:
7k = 3 * (130 - k)
7k = 390 - 3k
10k = 390
k = 390/10
<u>k = 39</u>

i dont know hope it helps
Y=-x^2 is just an inverted parabola, opening downward, with a vertex, its absolute maximum at (0,0) and decreasing without bound as x approaches ±oo
The answer is 2(x + 3)(x^2 + 1).
Steps:
2x^3 + 6x^2 + 2x + 6
2x^3 + 2x + 6x^2 + 6
2x(x^2 + 1) + 6(x^2 + 1)
(2x + 6)(x^2 + 1)
2(x + 3)(x^2 + 1)
