To find the inverse of the the function, it must be arranged in such a way that the independent variable be on the left side and the dependent variable on the right. So,f(x) = y = 3x/ (8 + x)y (8 + x) = 3x8y + xy = 3x8y = 3x - xy8y = x (3 - y)8y / (3-y) = xx = 8y / (3 -y)
Therefore,f-(x) = f(y) = x = 8y/ (3 - y)
Answer:
Yes, `18 of them wore a different costume
Step-by-step explanation:
49+36=85 which is not 103 children
So then you take 103 and subtract 85 (103-85= 18)
And your answer is 18, so 18 of the children wore a different type of costume.
Quadrant 3 should have coordinates of (-x,-y)....therefore, his x coordinate has the wrong sign
Time = 1,419/65 = about 21,8h
about 109 gallons of gas
the trip cost = $394,58 i guess
1. You can solve this problem like you would any other equation:
x-(y/7)=2
<em>*Subtract x from both sides*</em>
-y/7=2-x
<em>*Multiply both sides by 7*</em>
-y=14-7x
<em>*Divide both sides by -1*</em>
y=7x-14
2. This is the same as finding the slope. The equation for slope is (y2-y1)/(x1-x2).
(53-8)/(10-1)
45/9
5
3. The general formula for a linear equation is y=mx+b, where m is the slope and b is the y-intercept. The slope will remain the same because the lines are parallel. To solve for b, plug in the given coordinates:
4=0.5(6)+b
4=3+b
<em>*Subtract 3 from both sides*</em>
1=b
The equation is y=1/2+1
Hope this helps!!
