RM = x + 3 and MS = 2x –1 x=

and RM =

HELP

Step-by-step explanation:

Given RM = x+3 and MS = 2x-1, if M is on between R and S, then RM = MS

x+3 = 2x-1

collect like terms;

x - 2x = -1-3

-x = -4

Divide both sides by -1

-x/-1 = -4/-1

x = 4

Since RM = x+3, substitute x = 4 into the expression to get the lrngth of Rm.

RM = 4+3

RM = 7

Hence x = 4, RM = 7

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
