Answer:
1. f(x)=3
-12x-7
number three is really hard for me though sorry hope this first one helps though.
Step-by-step explanation:
You have to know what x is to completely solve but you can simplify it to, 20x^-40x -23
Answer:

Step-by-step explanation:
Let be
, then we must solve for
by means of the following expression:
(1)
Since it is an inverse trigonometric function, it can be solved only by numerical methods such as application of infinite series such as Taylor series. This approach is used for current scientific calculators. According to scientific calculator we have the following result:

Solve your equation step-by-step.
5(2y−2)+4=4
Simplify both sides of the equation.
5(2y−2)+4=4
(5)(2y)+(5)(−2)+4=4(Distribute)
10y+−10+4=4
(10y)+(−10+4)=4(Combine Like Terms)
10y+−6=4
10y−6=4
Add 6 to both sides
.
10y−6+6=4+6
10y=10
Divide both sides by 10.
10y/10 = 10/10
