Answer:
6. P, y=5x
5. P, y=2x
4. N, N
Step-by-step explanation:
If the graph is a straight line that goes through (0, 0), then it represents a proportional relation. The constant in the proportion (k) can be read from the graph as the y-value that corresponds to x=1.
__
6. P, y = 5x
5. P, y = 2x
4. N, N . . . . The y-intercept is not zero, so this is not a proportional relation.
Answer:

The answer is r= 1.666666667
1. You have that two sides of a triangle have lengths of 6 and 13. Then, by the <span>Triangle Inequality Theorem, you have:
a+b>c
a+c>b
b+c>a
3. Therefore, you have:
a=6
b=13
c<a+b
c<6+13
c<19
4. The difference between a and b should be lesser that c. Then
a-b<c
13-6<c
7<c
5. Therefore:
c=x
7<x<19
The correct answer is the option B: </span> B. 7<x<19<span>

Answer: y(t) = 600(0.921)^t
Step-by-step explanation:
Given:
Percentage yearly reduction = 7.9%
Initial mass m = 600 mg
time in years = t
An exponential function with yearly decay rate to determine the final mass of the substance is given as:
y(t) = m(f)^t
y(t) = final mass in milligram
m = 600
f = final mass fraction = 1 - 0.079 = 0.921
f = 0.921
Therefore, the exponential function is given as;
y(t) = 600(0.921)^t
