Answer:
Step-by-step explanation:
kinda confusing but ill do my best :/
if what youre saying is m(x) = -4 like x = -4 then do this
plug in -4 for x and solve
= 2(-4) - 10
= -8 - 10
= -18
or are you saying like the whole equation is equal to -4 and we need to solve for x do this
plug in -4 for 'y'
-4 = 2x - 10
then solve for x
6 = 2x
3 = x
sorry if this is confusing but i hope this helps <3
6x+6=8x
-6x -6x
-----
6=2x
6 divided by 2
x=3

Answer:
56
Step-by-step explanation:
JT=CJ+CT
4×+2=8×+5+55
4×+2=60-2
-4×=58
x=58/-4
x=-29/2
x=-14.5
JT=4x+2=4(-14.5)+2=-58+2=-56
