Answer:

1. a=3

2. a=3

3. a=9

Step-by-step explanation:

1. 9/a+9-4=12-56/8+3

We move all terms to the left:

9/a+9-4-(12-56/8+3)=0

Domain of the equation: a=0

a∈R

We add all the numbers together, and all the variables

9/a+9-4-8=0

We add all the numbers together, and all the variables

9/a-3=0

We multiply all the terms by the denominator

-3*a+9=0

We add all the numbers together, and all the variables

-3a+9=0

We move all terms containing a to the left, all other terms to the right

-3a=-9

a=-9/-3

a=+3

1) h(x)=3x3<br>g(x)= - 4x+1<br>Find (h+g)(10)

Aleksandr-060686 [28]

Answer:

$(h+g)(10) = 2691$

Step-by-step explanation:

$h(x) = 3x^3\\g(x) = -4x+1$

Adding both equations will make it:

$(h+g)(x) = 3x^3-4x+1$

Putting x = 10 will make it:

$(h+g)(10) = 3(10)^3-4(10)+1$

= 3(1000)-40+1

= 3000-39

= 2961
