Answer:
x=8/9
Step-by-step explanation:
5x+2(x-3)=-2(x-1)
5x+2x-6=-2x+2
7x-(-2x)-6=2
7x+2x=2+6
9x=8
x=8/9
Answer:
B
Step-by-step explanation:
y = (x + 1)/x
xy = x + 1
xy - x = 1
x(y - 1) = 1
x = 1/(y - 1)
Interswitch variables
f^-1(x) = 1/(x - 1)
Step-by-step explanation:
0 = sqrt(x - 4) + 3 Set equation equal to 0
-3 = sqrt(x - 4). Subtract 3 from both sides
the principle square root will only output positive values, since if it every outputted a negative value it would not be a function since a function cannot have 2 outputs for the same input.
no x-intercept
To find the value of your expression, you could use the following steps;
First lets substitute the value of x in the equation;
7 + 2(-3 - 9) - (-3+ 2)
Next, simplify the parenthesis;
7 + 2(-12) - (-1)
7 - 24 + 1 = -16
So your final answer would be; -16
