Ur output value is f(x).....so to do this problem u need to sub in 2/3 for f(x) and solve for the input value which is x
f(x) = -1/3x + 7
2/3 = -1/3x + 7 ...multiply everything by 3
2 = -x + 21
2 - 21 = - x
- 19 = -x
19 = x <== ur output
Answer:
-10
Step-by-step explanation:
1. First, let's simplify both sides of the equation.
2. To find the missing value to make the equation have infinitely many solutions, we need to make both sides of the equation equal.
3. Given that information, means that 4x - 10 has to equal 4x + (-10) because:
4. Now, with the information in #2, let's see if it's true:
-

-

- (0 = 0 means that the equation has infinitely many solutions)
Therefore, the missing number is -10.
To convert fractions to decimals, divide the denominator into the numerator
3/9= .333333
123/999=.123123
hope this helps
