Answer:

g(f(x)) = x² - 3

Step-by-step explanation:

g(f(x))=g(x²)

= x² - 3

Step-by-step explanation:

[tex]f(x) = {x}^{2} \\ g(x) = x - 3 \\ g(f(x)) = g( {x}^{2} ) = {x}^{2} - 3 \\ thank \: you[/tex]

Answer:

He was 16 years old.

Step-by-step explanation:

[tex] = (2021 - 5) - 2000 \\ = 2016 - 2000 \\ = 16[/tex]

Answer:

16 years old.

Step-by-step explanation:

Today's year is 2021

So,

[tex]2000 + 21 = 2021[/tex]

So, whoever's born in 2000, would be 21 years old in 2021. How old was Kollie five years ago?

[tex]21 - 5 = 16[/tex]

Kollie was 16 years old.

Answer:

2p - 1

Step-by-step explanation:

Answer:

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

hope this helps you

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.

Step-by-step explanation:

[tex]16a + {7}^{2} + 5 - 7a + c[/tex]

[tex]16a - 7a = (16 - 7)a = 9a[/tex]

[tex]\boxed{\green{= 9a + {7c}^{2} + 5 + c}}[/tex]

Answer:B 24 & 96

Step-by-step explanation:

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.

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.

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

Hope you got this.

[tex] \frac{5}{12} \: \: \: \frac{5}{8} \: \: \: \frac{5}{7} \: \: \: \frac{5}{6} [/tex]

Step-by-step explanation:

The trick to this is looking at the denominator. If the numerators are the same for all fractions you are comparing then things are going to be a bit easier for comparing them. The one that has the biggest denominator is small and the one with the smaller denominator is a bigger fraction.
