Answer:
B) 5
Step-by-step explanation:
Multiply both sides by 5
2(10x + 15) = 130
Distributive property
20x + 30 = 130
Subtract both sides by 30
20x = 100
Divide both sides by 20
x = 5
Answer: No
Step-by-step explanation:
I believe there would only be one describing both if they were parallel lines, but they are going two different directions in this graph. Correct me if I am wrong!
1. 28.57
2. 16
Hope this is right.

Answer:
x^4- x^3- 4x^2-3
Step-by-step explanation:
Given
f(x)= x^4- x^2+9
And
g(x)= x^(3 )+ 3x^2+12
We have to find
(f-g)(x)= ?
The operations on functions are as easy as the operations on numbers or polynomials.
We have to subtract the functions to find the above mentioned operation.
=(f-g)(x)=f(x)-g(x)
(f-g)(x)=[x^4- x^2+9]-[x^(3 )+ 3x^2+12]
The minus will change the signs of function g.
= x^4- x^2+9- x^(3 )- 3x^2-12
= x^4- x^3- x^2- 3x^2+9-12
=x^4- x^3- 4x^2-3
