Answer:
The constant of porportionality is k = 12.5; the equation that describes the relationship is y = 12.5x.
Step-by-step explanation:
When you divide the miles by the hours, it's always 12.5, meaning that k must be 12.5.
If x is the hours and k is 12.5, the equation that describes the relationship is y = 12.5x.
Answer:
$345
Step-by-step explanation:
$69 a day for 5 days that means 69 x 5 then that’s $345 hope this helps
42 degrees. Since the Ray is the angle bisector, that means it divides angle DEF into two angles with equal measure. So, divide 84 by 2 to get 42.

Answer: 4^15</h3>
Explanation:
The rule used is
a^b*a^c = a^(b+c)
Basically you add the exponents. This only applies if the bases are both the same. In this case, they're both 4 so the rule works out.
Using the rule, we get
a^b*a^c = a^(b+c)
4^5*4^10 = 4^(5+10)
4^5*4^10 = 4^15
Check the picture, notice the domain in red.
recall that the domain is the values for the x-coordinate, whilst the range is the values for the y-coordinate.
