Answer:
If a vertical line intersects the graph in all places at only one point, then the relation is a function.
If a vertical line intersects the graph in some places at more than one point, then the relation is NOT a function.
The simpliest way to do this is to turn both fractions into decimals
7/10 goes to 0.7 and 2/5 goes to 0.4
then the equation would be 0.7x + 20 = 0.4

Answer:3
Step-by-step explanation:easy 2 cups of pj plus cranberry juice is 3, get 6 by adding 3 again
X = 38
2x+20 = 96
2x+20 - 20
= 96 - 20
= 2x = 76
= 2x/2 = 76/2
x = 38
CHECKING:
2(38)+20
= 76+20
= 96
