Answer:
Step-by-step explanation:
a) sub in 600 for 6
600-25/40 =14.375
b) switch x and y
x=y-25/40
Solve for y
40x=y-25
y=40x+25
c)Plug in 2.5 for z(x)
2.5= x-25/40
100=x-25
x=125
Answer:
x - 2, if x > 5
Step-by-step explanation:
The vertical lines either side of the expression mean absolute value.
The absolute value of a number is its <u>positive numerical value</u>.
if x > 5 then as 5 > 2, the values inside the vertical lines will always be positive. Therefore, we can disregard the absolute value.
Therefore:
x - 2, if x > 5
To find the range (output values) of the expression, substitute x = 5 into the expression:
⇒ 5 - 2 = 3
Therefore, |x - 2| > 3, if x > 5
