associative law of addition.
Associative law of addition doesn’t matter how you group the given numbers to
add.
a + (b + c) = (a + b) + c
=> 19 + (11 + 37) or ( 19 + 11) + 37
=> 19 + (48) or (30) + 37
=> 67 or 67</span>
Answer:120
Step-by-step explanation:
calculate the sum of the negetive numbers 3x-40
=120
1:10 is one thing that is equivalent
In equation 1, When x = 0, y = -3 ( 0, -3)
And when y = 0, x = -3....( 3,0)
In equation 2, when x = 1, y = -4(1,-4)
and when y = 2, x = 5....(5,2)
You have to plot the points on graph paper and the solutions are where the two lines intersect.
You can use any points for x and y.
(x+1, y-1)
Because if you look at the corresponding points 1 is added to the x-value of the original point and 1 is subtracted from the y-value of the original point
