g(x) = 3x-1
f(x) = x + 5.
find g (f (4)
Answer:
g(x)=3
Step-by-step explanation:
Answer:
26
Step-by-step explanation:
g(x) = 3x-1
f(x)= x+5
g(f(4)
plug 4 into f
f(4)
now apply x+5
f(4)=4+5=9
plug 9 into g
g(9)
now apply 3x-1
g(9)=3(9)-1
3 ×9= 27
27-1=26
hence the answer is 26

Step-by-step explanation:
Given M ,N find the value of x
Answer:
x = 59 , y = 44
Step-by-step explanation:
(2x + 18) and (x - 15) are adjacent angles on a straight line and sum to 180°
2x + 18 + x - 15 = 180 , collect like terms
3x + 3 = 180 ( subtract 3 from both sides )
3x = 177 ( divide both sides by 3 )
x = 59
Then
x - 15 = 59 - 15 = 44
y and (x - 15) are corresponding angles and are congruent , then
y = 44

Answer:
b = 12
Step-by-step explanation:
hi! so this looks like a right triangle because it has a right angle which is 90 degrees! that means we can use the Pythagorean theorem to solve for the missing leg.
The Pythagorean theorem: [tex]a^{2} + b^{2} = c^{2}[/tex]
a and b will be the two shorter legs, so it does not matter which of the two legs are which! in this problem, 5 and b (the missing leg) are the two shorter legs! c is always the hypotenuse, which is the sloped-looking line. in this problem, 13 is the hypotenuse! this line is the longest side on every right triangle!Let's solve for the missing leg now!
1) first, we need to plug in the missing numbers into the equation
[tex]5^{2} + b^{2} = 13^{2}[/tex]
2) next, let's simplify the problem
[tex]25 + b^{2} = 169[/tex]
3) now, let's isolate the variable, b
[tex]b^{2} = 144[/tex]
4) finally, we have to take the square root of b so it will be b not [tex]b^{2}[/tex]
b = 12
Let's plug in our answer to the equation to check if it is correct!
[tex]5^{2} + 12^{2} = 13^{2}[/tex]
25 + 144 = 169
169 = 169 hooray!
you do not have to do all of this work if you memorize the Pythagorean triples!
(3, 4, 5), (5, 12, 13), (7, 24, 25), (8, 15, 17) , (9, 40, 41)these are automatic matches! for example: [tex]3^{2} + 4^{2} = 5^{2} --> 9 + 16 = 25 --> 25 = 25[/tex]comment or message if you have any questions :)

Does anybody know the answer to this question f(x)=x^3-x^2-10x-8
Answer:
(X+1) (x - 4) (x+2)
Step-by-step explanation:
All the coefficients are integers so apply the rational zeros theorem.
The coefficient of x^3 is 1.
Divide (x^3-x2-10x-8)(x+1) = x^2-2x-8 with remainder = 0
The remainder is 0. (x+1) is a factor.
(x + 1) ( x^2 - 2x - 8)
x^2 - 2x - 8 (-4 * 2= 8) and -4 + 2 = -2)
= (x -4) (x+2)

Rate of change = change in distance ÷ change in time
= (3126 ft - 1735 ft) ÷ (120 s - 45 s)
= 1391 ft ÷ 75 s
≈ 18.55 ft/s
∴ the rate of change is 18.55 ft/s.Find the elapsed time of 8:45AM to 1:10 PM
Answer:
the answer would be 11 hours and 25 minutes
Step-by-step explanation:
Answer:
4.42 hours
The reason why is by adding, 8:45 can round up to 9, and 1:10 can round down to 1, this make it simpler. 8:45+15 1:10-10
9AM to 1PM
9AM+3=12PM, add 1 and you get 1 pm=4 hrs, add 15+10, and you get somewhere close to it.

Step-by-step explanation:
[tex] (\dfrac{10^{-2}}{10^3})^{-1} = [/tex]
When you divide powers with the same base, subtract the exponents.
[tex] = (10^{-2 - 3})^{-1} [/tex]
[tex] = (10^{-5})^{-1} [/tex]
To raise a power to a power, multiply the exponents.
[tex] = 10^{-5 \times (-1)} [/tex]
[tex] = 10^5 [/tex]
[tex] = 100,000 [/tex]
Han is multiplying 10x^4 by 5x^3 and gets 5x^7. He says that 0.5x^3 is not a polynomial because 0.5 is not an integer. What is the error in Han’s thinking? Explain your reasoning.
The result of the product with [tex]5x^7[/tex], we can see that Han neglected the zero taking 50 the same as 5 which is wrong
Given the polynomial functions
r(x) = [tex]10x^4[/tex]
t(x) = [tex]5x^3[/tex]
Taking the product of both functions:
P(x) = r(x) * t(x)
P(x)= [tex]10x^4\times 5x^3[/tex]
P(x) = [tex](10\times 5) \times(x^4\times x^3) = 50x^7[/tex]
Comparing the result of the product with [tex]5x^7[/tex], we can see that Han neglected the zero taking 50 the same as 5 which is wrong.

Answer:
length = x+6
width = x-6
Step-by-step explanation:
The area of rectangle is:
[tex] \displaystyle \large{ A= l \times w}[/tex]
where A is area, l is length and w is width.
We know the area of this rectangle or table since we are given A = x^2-36.
First, substitute A = x^2-36 in.
[tex] \displaystyle \large{ {x}^{2} - 36 = lw}[/tex]
Then we factor x^2-36, use the difference of two squares:
[tex] \displaystyle \large{ (x + 6)(x - 6) = lw}[/tex]
Compare the terms.
First, we have to understand that length is always longer or greater or have more values than width.
Hence length cannot be x-6 and width cannot be x+6 either.
Thus:
[tex] \displaystyle \large{length = x + 6} \\ \displaystyle \large{width = x - 6}[/tex]
In how many ways can a committee
of 5 men and 3 women be selected
from 9 men and 7 women ?
Answer：
use the same method
Step-by-step explanation:
Men=5
Women=3
Available Strength:
Men=7
Women=6
Objective:Finding no of such committees where particular 2 women are never together.
So initially ,Total possible number of commitee=7c5×6c3=420.
Now we need to find total committes where two particular women say(Sita and Gita ) are never together.
Approach—->
As the commitee requires 5 men and 3 women.
Let us first find number of committees where Sita and Gita are always together.
Hence we reserve 2 women seats for them.
Now we need one women out of remaining 4 women.
So possible number of such commitees 7c5×4c1.
=84.
Hence number of committees where Sita and Gita are never together
=420–84
=336.
