Let x be the number of hours she jogs, and y be the number of hours she bikes.
The total time would then be x + y = 5
The total distance (based on the given speeds) would be 6x + 12y = 50
Multiply the first equation by 6 to get 6x + 6y = 30
Subtract this from the second equation to get 6y = 20
y = 10/3 or 3 1/3
Substitute this value back into the first equation to get x = 5/3 or 1 2/3
Therefore, Yolanda will have to jog 1 2/3 hours and bike 3 1/3 hours.

Answer:
the length of the longer piece of cable is 24 ft
Step-by-step explanation:
shor piece = s
Long piesce = s+9
s + s+9= 39
2s = 30
s = 15
short = 15
15 +9 = 24
long = 24
15+24 = 39
Answer:
B. −2
C. −1
E. 1
Step-by-step explanation:
He have been given a polynomial function 
. We are asked to find the zeros of our given function.
To find the zeros of our given function, we will equate our function with zero and solve for x as:
Now, we will factor our equation by grouping method.
Now, we will use difference of squares 
Using zero product property, we will get:
Since the zeros of our given function are 
, therefore, options B, C and E are correct choices.
