this makes no sense, so imma guess for u.
C
We can simplify across between the 5 and the 50 and also between the 42 and the 3.
Answer:
4 x minus 5 y = negative 5 and 3 x + 10 y = negative 20
Step-by-step explanation:
The equations
4 x - 5 y = 5 (red)
3 x + 10 y = 20 (blue)
4 x - 5 y = -5 (green)
3 x + 10 y = -20 (purple)
are shown in the picture attached. As we can see there, the point (–2.7, –1.2) is on the intersection of the purple and green lines. Therefore is the solution of the system:
4 x - 5 y = -5
3 x + 10 y = -20
Answer:
The midpoint of points
is
.
Step-by-step explanation:
Given points are
. We need to find the midpoint of the line segment.
The formula of finding midpoints between the point
is

W have points
. And 
Let us plug the value in Equation (1)


So, the midpoint of points
is
.
Answer:
Step-by-step explanation:
This is the associative property for addition. In informal language, it says under addition, the order of the addition is not critical.
