Which expression is equivalent to 6m + (m – 2)(m + 7) + 3?
LuckyWell [14K]

Hello from MrBillDoesMath!

Answer:

m^2 + 11m - 11, which is the first choice


Discussion:

6m +  (m-2)(m+7) +3 =

6m  + (m^2 + 7m - 2m -14) + 3 =

(6m + 7m - 2m) + m^2 + (-14 + 3) =             combine similar terms

11m + m^2 -11 =

m^2 + 11m - 11


which is the first choice


Thank you,

MrB

Can somebody number the problem and work it out for me thanks and btw it’s solving system by graphics
adoni [48]

Answer:

Solutions are (3,1) and (4,2)

Step-by-step explanation:

Graph is shown in the attached sheet

Given are two systems of equations and we have to solve them using graph

For graphing let us first prepare table for x and y.

1) y=\frac{-2x}{3} +3:\\y=2x-5

I line                                                             II line

x     0   4.5    3                              x       0      2.5     3

y      3   0       1                              y       -5      0        1

The two lines intersect at (3,1)

Hence solution is (3,1)

--------------------------------------------

2) y=\frac{x}{2} \\-6x+3y=-18

I line                                                             II line

x     0    2    4                              x       0      6     4

y      0   1      2                             y       3      0     2

The two lines intersect at (4,2)

Hence solution is (4,2)
