What is the solution for the system of equations? y=−x+4 y= x−2

Mathematics
1 answer:
MissTica3 years ago
6 0

Answer:

(3, 1 )

Step-by-step explanation:

Given the 2 equations

y = - x + 4 → (1)

y = x - 2 → (2)

Substitute y = x - 2 into (1)

x - 2 = - x + 4 ( add x to both sides )

2x - 2 = 4 ( add 2 to both sides )

2x = 6 ( divide both sides by 2 )

x = 3

Substitute x = 3 into either of the 2 equations and solve for y

Substituting into (2)

y = 3 - 2 = 1

solution is (3, 1 )

George had one sheet of paper. He cut it into 6" x 5", and 3" x 6". What were the dimensions and total area of his original shee
Deffense [45]

Answer:l={8}'' ,b={6}'',l={6}'' ,b={8}''

and area is=48 inch square

Step-by-step explanation:

area of sheet=l\times b

area of sheet first={6}''\times {5}''

=30 inch square

area of sheet second={3}''\times {6}''

=18 inch square

total area of both sheet=30+18

=48 inch square

area of sheet=l\times b

=48 inch square

l={6}'' ,b={8}''

or

l={8}'' ,b={6}''

perimeter of sheet

=2\left ( l+b \right )

=2(6+8)

={28}''

Instructions: Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.
Morgarella [4.7K]

Answer:

y = 3x - 13................slope= 3, point= (5,2)

y = 3x + 11.................slope= 3, point= (2,17)

3y = x + 11................slope= 1/3, point= (-5,2)

3y = x - 13................slope= 1/3, point= (19,2)

Step-by-step explanation:

To match each equation to its slope and point, remember that an equation in y = mx + b has slope m. The point must also satisfy or make true the equation when substituted for (x,y).

y=3x-13  has slope 3. The point (2,17) make it false. But (5,2) makes it true.

17 = 3(2) - 13                 2 = 3(5) - 13

17 = 6-13                       2 = 15 - 13

17 = - 7  False              2 = 2 True

y=3x+11  has slope 3. This means (2,17) must be true.

3y=x+11  can be converted to y = 1/3x + 11/3. It has slope 1/3. Test each point.

2= 1/3(19) + 11/3                 -2 = 1/3(17) + 11/3        2 = 1/3(-5) + 11/3

2 = 19/3 + 11/3                    -2 = 17/3 + 11/3          2 = -5/3 + 11/3

False                                    False                        2 = 6/3    True

3y=x-13 can be converted to y = 1/3x - 13/3. It has slope 1/3. Test each remaining point.

2= 1/3(19) - 13/3                 -2 = 1/3(17) - 13/3        

2 = 19/3 - 13/3                    -2 = 17/3 - 13/3          

2 = 6/3                                -2 = 4/3

True                                   False
