What is the intersection (x, y) of the two lines generated by the 2 equations: y= x+3
y=-x +7

x=2

y=5

Step-by-step explanation:

y= x+3...(1)

y= -x+7...(2)

(1) + (2):

y+y= (x+3) + (-x+7)

2y= (x-x) + (3+7)

2y= 10

y= 5

By substituting y=5 into (1),

we have

5= x+3

x+3=5

x= 5-3

x= 2

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
