Answer:
x= -9/11
or alternative form:
x= 0.81
Step-by-step explanation:
2x4-3x3-20x-21=x-3
Cracked:all=3:4
3/4=x/28
cross multiply or times both sides by 28
3*7=x
21=x
21 are cracked (bad deal)
<span>Find the inverse function of f.
f(x)=(1+3x)/(5-2x)
Interchange x and y to get:
x=(1+3y)/(5-2y)
Solve for y as follows:
5x-2xy=1+3y
3y+2xy=5x-1
y(3+2x)=5x-1
y=(5x-1)/(2x+3)
this is the inverse function</span>
Answer:
you are correct
Step-by-step explanation:
since there is a box in the angle, it means it's 90°, so if the 1rst angle is 30°, the other one has to be 60°
