Answer:
The two that are blank are 2 and 7
Step-by-step explanation:
graph B ( the lower one )
for a function to be defined there can only be one value of y for each value of x
graph A has more than 1 value of y for given values of x
for example ( - 1, 4 ) and ( - 1, - 4 ) thus is not a function
graph B only has 1 value of y for a given value of x thus is a function

<span>In order to determine the value of the numbers, we can set up algebraic equations to solve. For this case, we need to set up two equations since we have two unknown numbers. We do as follows:
let x = first number and y = second number
From the problem statement, we set up equations.
Equation 1 - the numbers have a difference of 0.7
x - y = 0.7
Equation 2 - the numbers have a sum of 1
x + y = 1
Solving for x and y via substitution method,
x - y = 0.7
(1-y) - y = 0.7
1 - 2y = 0.7
-2y = 0.7 - 1 = -0.3
y = 0.15 or 3/20
x - 0.15 = 0.7
x = 0.85 or 17/20
Thus, the two numbers are 0.15 and 0.85.</span>
