Answer:
28
Step-by-step explanation:
Cross multiply
18k = 12 x 42
18 k = 504
k = 504/18
k = 28
The standard form of the equation of circle is:
(x – h)^2 + (y – k) ^2 = r^2
Where the center being at the point (h, k) and the radius
being r
Substituting the values to the equation:
<span>(-15 - (-7)) ^2 + (y – (-1)) ^2 = 13^2 </span>
64 + (y +1) ^2 = 169
(y +1) ^2 = 105
y + 1 = 10.247
<span>y = 9.247</span>
Two mountain bikers are riding on a 35-mile trail. Abel started at the beginning of the trail and is riding at a rate of 14 miles per hour. Neal started 6 miles ahead of Abel and is riding at a rate of 11 miles per hour. When will the boys be at the same point on the trail?
If Abel’s journey is represented by the equation d = 14t, where d represents the total distance and t represents time in hours, what equation represents Neal’s journey?
d = <u>11</u>t + <u>6</u>
