When solving an equation, Carmen's first step is shown below. Which property justifies Carmen's first step? \text{Original Equation:}
Original Equation:
-2(7x^2-1)+6 =
−2(7x
2
−1)+6=
\,\, 8x^2-10
8x
2
−10
\text{First Step:}
First Step:
(7x^2-1)-3 =
(7x
2
−1)−3=
\,\, -4x^2+5
−4x
2
+5

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
