Answer:

-66, 80

Step-by-step explanation:

Let x represent the first number. Then the second number is 14-x, and the difference is ...

x - (14-x) = -146

2x = -132 . . . . . . add 14, collect terms

x = -66 . . . . . . . . the first number

14-x = 14-(-66) = 80 . . . . . . the second number

Answer:

-66 & 80

Step-by-step explanation:

Let the two numbers be x and y

x + y = 14 (1)

x - y = -146 (2)

Adding (1) & (2),

2x = -132

x = -66

y = 14 - x = 14 - (-66) = 14 + 66

y = 80

Answer:

Step-by-step explanation:

You input will always be your x so you just substitute x with 10 and simplify. Which is 30 minus 6, thus 24. :)

What is the value of 9(n+2)−5n for n=14? 3 9 10 19

Murrr4er [49]

If you want to know the value of a function, you need to substitute the variable (here n) for the value:

so in the function

9(n+2)−5n

we substitute n with 14:

9(14+2)−5*14

first calculate the inside of the bracket:


9*16−5*14

9 times 16 is 144

144-5*14

5*14 is 70, so we have

144-70=74

so the answer should actually be 74!
