The equation of the line is: y=2/-5x + 3 3/5
Answer:
7
Step-by-step explanation:
the area of a triangle is base*height/2. so, if the area is 14 mm^2, we have to figure out how much the area would be without dividing by 2. the opposite of division is multiplication, so 14*2=28. now that we know how much the area would be if we didnt divide by 2, we have to figure out the base. the equation is:4x=28. we divide 4 on each side and we get x=7.
To find the inverse, we need to solve for x in term of f(x)
f(x) = 5x + 4
5x + 4 = f(x)
Solve for x
5x + 4 = f(x)
5x = f(x) - 4
x =
![\cfrac{f(x)-4}{5}](https://tex.z-dn.net/?f=%20%5Ccfrac%7Bf%28x%29-4%7D%7B5%7D%20)
x acts as the invers of f(x), and f(x) is the invers of x, so the inverse function will be
f⁻¹(x) =
