answer: 1st train = 364 mph, 2nd train = 356.2

step-by-step explanation:

train 1: x + 7.8

train 2: x

train 1 + train 2 = sum

x + 7.8 +     x       = 720.2

            7.8 + 2x = 720.2

                    2x = 712.4

                      x = 356.2

train 1: x + 7.8

  = 356.2 + 7.8

  = 364

answer:

for -12 and -5, it is 7. for -12 and -7 it is 5

hope this ! brainliest appreciated!

hello from mrbilldoesmath!

answer:

y = 2x + 11

discussion:

slope-intercept from is   y = mx + b. rewrite the point-slope equation as follows:

y - 3         = 2(x+4)                   =>   add 3 to both sides

y - 3 + 3 =   2(x+4) + 3             =>

y = 2x + 8 + 3                         =>   combine like terms

y = 2x + 11
