X=23 First, you have to subtract 12 by 12 to cancel it out. Next, you have to do the same thing to 20.05. 20.05 minus 12 is 8.05. All you have left is .35x. To get rid of the this you have to divide .35x by .35. Now all you have left is x. Finally you have to do the same thing to 8.05. 8.05 divided by .35 is 23. So, x=23
F(x) is another way of saying y
Y=2x-4
For the inverse you trade the x and y
X=2y-4
Then get y by itself
Add 4 to both sides
X+4=2y
Divide both sides by 2
X+4/2Z
Answer:
See answers below
Step-by-step explanation:
The equation for slope-intercept form is y=mx+b where m is the slope and b is the y-intercept. Solving for y will change the original equation into slope-intercept form:
We can do the same thing for the second equation:
Answer:not true
Step-by-step explanation:
To say not true we need only one example so we can take x as -5
[-5]= [-5+1]
5 not equal with 4
Answer:
Step-by-step explanation:
x^2 + 12x + 32 = 0
(x + 4)(x + 8) = 0
x + 4 = 0 x + 8 = 0
x = -4 x = -8
smaller x = -8
larger x = -4
