Step-by-step explanation:
x = the number
2x - 25 = x
2x = x + 25
x = 25
3. The answer is 18 because 12➗4= 3 so 6*3=18
Answer:
simplified in the exact form: 8/3
simplified in decimal form: 2.6
simplified in mixed number form: 2 2/3
Answer:
f^-1(x) = ( x + 6 )/4
Step-by-step explanation:
f(x) is the same as...y = 4x + 6....and then try to make x the subject of formula
y + 6 = 4x
x = (y + 6)/4....then when writing f^-1(x)...replace y with x
f^-1(x) = ( x + 6 )/4
