Answer:
f(2/9) = 1
Step-by-step explanation:
f(x) = 3x + 1/3........find f(2/9)...so sub in 2/9 for x
f(2/9) = 3(2/9) + 1/3
f(2/9) = 6/9 + 1/3
f(2/9) = 2/3 + 1/3
f(2/9) = 3/3
f(2/9) = 1 <=====
17, 19, 22, 25, (27.) You can get this by plugging in numbers or seeing what needs to be on the other side of 22 to balance it out.
Only 35:28 is equivalent to 5:4
Further explanation:
Given
5:4
We have to check each ratio, if it can be simplified to be equivalent to 5:4
<u>1:2</u>
The ration cannot be simplified in any way to 1:2 so it is not equivalent.
<u>8:14</u>
Simplified to: 4:7 => Not equivalent to 5:4
<u>35:28</u>
It can be simplified to 5:4 by dividing by 7.
Only 35:28 is equivalent to 5:4

If your Main Street line has a couple of points that you can find the coordinates ( x1, y1) and (x2, y2) you could determine the slope of the Main Street line : m= (y2-y1)/(x2-x1). Or maybe you can determine what the slope is from the line being a particular line , horizontal, etc. The slope of your path line would be m1 = -1/m. Use some point on this path to write the equation of a line in point- slope from. Suppose ( x3,y3) would be a point , ( look for example for the entrance coordinates), write y= m1(x-x3)+ y3 and plug in then values of m1, x3, y3 to have your path line equation. ~Nesabug :3
Answer:
f^(-1)(x) = 4x + 48.
Step-by-step explanation:
Is suppose the function is f(x) = 1/4 x - 12
This is equivalent to the line y = 1/4 x - 12.
To get the inverse, change the x and y:
x = 1/4 y - 12
Now solve for y:
x + 12 = 1/4 y
y = 4x + 48
So the inverse f^(-1)(x) = 4x + 48.
