Answers
Answer:
There is no sign it should be unitless
Step-by-step explanation:
Answer and Step-by-step explanation:
Assuming that both values of a and b are positive, we get the result to be positive, so a + sign (though you don't have to put that in front of the value).
When you multiply 2 positive values, the result is always positive.
Multiplying a positive and a negative value results in a negative value.
Multiplying 2 negative values together results in a positive value.

Limits of a Function
If [tex]\displaystyle \lim_{x \to 1} \frac{f(x)-8}{x-1} = 10,[/tex] find [tex]\lim_{x \to 1} f(x).[/tex]
Answers
We are given the equation:
[tex]\lim_{x \to 1} \frac{f(x)-8}{x-1} = 10[/tex]
which can be rewritten as:
[tex]\frac{\lim_{x \to 1}[f(x)-8]}{\lim_{x \to 1}[x-1]} = 10[/tex]
[tex]\lim_{x \to 1}[f(x)-8] = 10*\lim_{x \to 1}[x-1][/tex]
[tex]\lim_{x \to 1}[f(x)-8] = \lim_{x \to 1}[10x-10][/tex]
which means that..
[tex]f(x) - 8 = 10x - 10[/tex]
[tex]f(x) = 10x - 10 + 8[/tex]
[tex]f(x) = 10x - 2[/tex]
Finding the limit:
[tex]\lim_{x \to 1} f(x) = \lim_{x \to 1} (10x - 2)[/tex]
[tex]\lim_{x \to 1} f(x) = 10(1) - 2[/tex]
[tex]\lim_{x \to 1} f(x) = 8[/tex]
Answer:
8.
Step-by-step explanation:
lim x --> 1 of 10x - 10 / (x - 1)
= lim x -->1 of 10/1 ( Because when x = 1 the function = 0/0 so we can apply
L'hopitals rule which states that that if f(x)/ g(x) = 0/0 when x = limit value, then the limit is = f'(x) / g'(x))
So f(x) - 8 = 10x - 10
f(x) = 10x - 10 + 8
f(x) = 10x - 2
- and the limit as x ---> 1 of this is
10(1) - 2
= 8.

if you are three years older than your cousin and both your ages sum to 25 how old are you and how old is your cousin
Answers
Answer:
You are 14 years old. Your cousin is 11 years old.
Step-by-step explanation:
Let x = cousin
Let x + 3 = you
x + x + 3 = 25
Solve out left side
2x + 3 = 25
Subtract both sides by 3
2x = 22
Divide both sides by 2
x = 11
11 + 3 = 14
Answer:
my age=14 years
my cousin's age=11 years
Step-by-step explanation:
x+3=my age
x =cousin's age
x+x+3=25
2x+3 =25
2x=25-3
2x=22
x=11
therefore cousin's age=11 years
my age =x+3
=11+3
=14 years

f(x) = 5x – 1
to find the inverse equate f(x) to y
That will be
f(x) = y
>>>>
Interchange the terms >>>
x = 5y - 1
then make y the subject
then we have
5y = x + 1
then if you divide both sides by 5
y = x+1/5
therefore f^-1(x)= x + 1/5

Also could someone please explain how to do this??
Answers
9514 1404 393
Answer:
x = -20
Step-by-step explanation:
First, simplify the equation. Eliminate parentheses and combine terms.
3(x -1) -8 = 4(1 +x) +5 . . . . . . . given
3x -3 -8 = 4 +4x +5 . . . . . . . . eliminate parentheses (distributive property)
3x -11 = 4x +9 . . . . . . . . . . . . combine like terms
We can put all the x-terms on the right by subtracting 3x from both sides.
3x -11 -3x = 4x +9 -3x
-11 = x +9
And we can get the x-term by itself by subtracting 9 from both sides.
-11 -9 = x +9 -9
-20 = x . . . . . . . . . . this is the solution
__
Check
3(-20 -1) -8 = 4(1 -20) +5
3(-21) -8 = 4(-19) +5
-63 -8 = -76 +5
-71 = -71 . . . . . . . . . true, the answer checks OK
_____
Additional comment
We observe that the two x-terms are 3x and 4x. The smaller of these is 3x, so when we subtract that from 4x we will have a positive result. That is why we chose to subtract 3x, even though it leaves the x-term on the right side of the equation. We could have subtracted 4x to get -x -11 = 9. I find it easier not to make a mistake if the variable has a positive coefficient.
