A system of equations is shown below. y=-x+3 y=3-/2 Does the ordered pair (-4, 6) satisfy the system? Justify your answer.

(2.5, 5.5)

Step-by-step explanation:

The system of equation is not well written

Let the system of equations be;

y = x+3

y = 3x - 2

Equate both expressions to get x;

x + 3 = 3x - 2

x - 3x = -2-3

-2x = -5

x = 5/2

x = 2.5

Get the value of y;

y = x+3

y = 2.5+3

y = 5.5

Hence the required coordinate point is (2.5, 5.5)

Note that the second equation was assumed but the same steps can be taken to solve the given equation

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

multiple all that
