The y-intercept for f(x)=|x|-5 is (-5). Just look at the function as slope-intercept form and find the number that is not being multiplied by x. That number will usually be your y-intercept.
Answer:
The exact value of the function for the given x-value is of -5.
Step-by-step explanation:
In this question, we compute the numeric value of the function f(x) for x = -1, that is, we replace every instance of x in the function by -1.
f(x) = 5x for x = -1
The exact value of the function for the given x-value is of -5.
The simplified expression for the total amount in dollars Dave has in his pocket is $(6n+50) and when n = 5 then he has $80.
According to the question,
We have the following information:
Dave has one $20 bill, three $10 bills, and the same number of $5 bills and $1 bills in his pocket.
The number of $5 and $1 bills are n.
a) So, we will have the following expression for the total money he has:
1*20+3*10+5n+n
20+30+5n+n
Now, adding the numbers together and the terms with the same variable together:
$(6n+50)
b) Now, when n = 5:
$(6*5+50)
$(30+50)
$80
Hence, the simplified expression for the total amount in dollars Dave has in his pocket is $(6n+50) and when n = 5 then he has $80.
