Given:
The function is

To find:
The range value if the domain value is 1.75.
Solution:
Domain is the set of input values and range is the set of output values.
Here, range value if the domain value is 1.75. It means the value of function f(x) at x=1.75.
Substitute x=1.75 in the given function.



Therefore, the required range value is 4.5.
When multiplying binomials, one takes the first binomial and multiply each term by the first term of the second binomial, and then you do the same with the second term of the second binomial, to obtain:
4a^2+14a-2a-14
4a^2+12a-14
(fg)(x) = (x^3 -4x+2)(x^2+2)
(fg)(x) = x^5 - 4x^3 + 2x^2 + 2x^3 -8x + 4
(fg)(x) =x^5 - 2x^3 + 2x^2 -8x + 4
answer
x^5 - 2x^3 + 2x^2 -8x + 4
Answer:
D
Step-by-step explanation:
6x + c = k ( isolate the term in x by subtracting c from both sides )
6x = k - c ( isolate x by dividing both sides by 6 )
x = 
Answer:
1) A system of two linear equations to represent this problem
x+y=20 and x-y=12
2) The numbers are x=16 and y=4
Step-by-step explanation:
Let x and y be the two numbers
Given that the sum of the two numbers is 20
That is 
and the difference is 12
That is 
1) A system of two linear equations to represent this problem


2). Noe Solve the system to find the 2 numbers:
Adding the equations (1) and (2) we get


_____________
2x=32

Therfore x=16
Now substitute x=16 in equation (1) we get


Therefore y=4
Therefore the numbers are x=16 and y=4
