f(x) = -5x - 15
Let y = f(x)
y = -5x - 15
Switch the x and y places, and solve for y:
x = -5y - 15
-5y = x + 15
y = (x + 15)/-5
y = -(x/5) - 3
So the inverse of : f(x) = -5x - 15 is
-x/5 - 3
Answer: x = cost of games
y = cost of console
---
x + y = 540
x = 3y
---
put the system of linear equations into standard form:
---
x + y = 540
x - 3y = 0
solution:
x = cost of games = $405
y = cost of console = $135
12 I think because its half 24 and 3 x4 =12
Answer:
11.5847..
Step-by-step explanation:
Answer:
x = 145
Step-by-step explanation:
x and 35 are adjacent angles and are supplementary, sum to 180° , then
x + 35 = 180 ( subtract 35 from both sides )
x = 145
