Answer:
19/20
Step-by-step explanation:
7/10+1/4
LCM of 10 and 4 is 20,
denominator is 20
10 x 2 is 20 and 4 x 5 is 20
so we have to do 7 x 2 and 1 x 5
14/20 + 5/20 = 19/20
1/6 x = 2/3 |multiply both sides by 6
x = 12/3
x = 4
Functions:graph B,mapping A, Table B
Grape B is a function because it passes the vertical line test ( meaning when I draw a vertical line any where on the graph the line only touched one point),mapping A is a function because each x value has only one y value same with table.
Non function: graph A, mapping B, Table A
Graph A does not pass vertical line test so it is not a function, mapping B and Table A both have an x value that has two y values and that is not a function.
