Solutions to Systems and Solving By Graphing Determine whether each of the following points is a solution to the given system. Justify your answer.

a) (-10,-1) y= 1/2x+4, y=4x+30
b) (2, 3/2) y= 8-x/4, y= 5/4x-1

step-by-step explanation:

here's what happens:

1) the graph of f   = x^2 is shifted 2 units to the right.

2) the resulting graph is reflected in the x-axis, so that the parabola now opens down.

3) this final result is transformed up by 5 units.

first one is a: renaming a fraction. second one is c: de-c

my explanation is that these were the answers on edg : )

i dont know sorry

step-by-step explanation:

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
