Chana and Josiah started skating at the same time in the
same direction, but Josiah had a head start 10 meters past
the starting line. Chana skated 3 meters per second and
Josiah skated 2 meters per second.
Here's a graph that shows a system of equations for this
scenario where x is the number of seconds since Chana
and Josiah started skating and y is the distance in meters
from the starting line.
y (distance)
line b: y = 32
60+
line a : y = 10 + 23

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.

if x decreases by 4 then y increases by 10
