Answer:
x = 55 or x = 15
Step-by-step explanation:
Solve Absolute Value.
We know that either 1/5x - 7 = 4 or 1/5x - 7 = -4.
1/5x - 7 = 4
1/5x - 7 + 7 = 4 + 7
1/5x = 11
1/5x (5) = 11 (5)
x = 55 (one possibility)
1/5x - 7 = -4
1/5x - 7 + 7 = -4 + 7
1/5x = 3
1/5x (5) = 3 (5)
x = 15 (second possibility)
Answer:
2x+9 is the equation
x = 10.5
Step-by-step explanation:
2x + 9 = 30
2x = 30 - 9 = 21
x = 21 ÷ 2 = 10.5
Hope this helps!
Answer:
the function f(x) = x + 1 adds 1 to any value you feed it. You give it a 5, this function will give you a 6: f(5) = 5 + 1 = 6. Functions do have a criterion they have to meet, though. And that is the x value, or the input, cannot be linked to more than one output or answer.
Step-by-step explanation:
we could define a function where the domain X is again the set of people but the codomain is a set of number. For example , let the codomain Y be the set of whole numbers and define the function c so that for any person x , the function output c(x) is the number of children of the person x.
hop u get it
