F(5) = -4(25) - 3 = -100 -3 = -103
answer
f(5) = -103
g(-5) = 3(-5) - 1 = -15 -1 = -16
answer
g(-5) = -16
Answer : The equation could you use to find p is, 
Step-by-step explanation :
Let the cost of 1 pen be, 'x'
and the cost of 1 pencil is, 'p'
As we are given that total cost of 1 pen and 1 pencil is $2.10. The equation will be:
............(1)
And we have also given that the pen costs twice as much as a pencil. The equation will be:
............(2)
Now put the equation 2 in equation 1, we get:


Thus, the equation could you use to find p is, 
Answer:
The answer is .9.
Step-by-step explanation:
Steps Ex. 1 Ex. 2
Round a number to the nearest tenth 3.14 .883
Find the hundredths' place. 3.14 .883
Less than 5, round the tenth down. 3.1
If it is 5 or more, round the tenth up. .9
That is your explanation. The answer is .9
D: (-infinity, 0) U (0, infinity) because you cant have a zero in the bottom of the fraction
