Answer:
1/3x - 3
Step-by-step explanation:
To find the inverse, we exchange x and y and then solve for y
y =3x+9
Exchange x and y
x = 3y+9
Then solve for y
Subtract 9 from each side
x-9 =3y+9-9
x-9 = 3y
Divide by 3
1/3(x-9) = 3y/3
1/3(x-9) = y
Distribute
1/3x-3 = y
The inverse is 1/3 x -3
So she had one Board and she cut it in two parts. I part is 1 7/8 feet long and the other part is 3 1/2 feet long
Answer: what’s the assignment and what are the questions?
The Correct choices are :
- The rate of change is not constant
- This is a negative relationship
- The relationship is non - linear
- The dependent variable is selling price
- The independent variable is age
So because it’s parallel you’re gonna have the same slope. You need to use point slope formula to find the equation of the line
y-y1=m(x-x1). Here, x1= -1 and y1=3. Your m is the slope which is parallel which means you’re gonna have the same slope. Our equation is given in y=mx+b form so our m is 2 so the parallel slope is 2. So m=2, x1=-1, y1=3
Plugging all of these in you have
y-3=2(x-(-1))
Simplifying we have
y-3=2(x+1)
Applying distributive property we have
y-3=2x+2
adding 3 to each side we get
y=2x+5
Hope this helps!!!
