Mean = sum/no. *of observations
Initially, number of people = 5 & let the sum of their ages be S.
=> 31 = S/5
=> 155 = S
When one more entered, number = 6. Let his age be 'a'.
Sum of ages = S + a = 155 + a
=> 30 = (155 + a)/6
=> 180 = 155 + a
=> 25 = a

Which graph represents the solution for the equation 3x + 2 = 5x?
**+
(x - 12y = -4
( x - 9y = 7
9514 1404 393
Answer:
(x, y) = (40, 11/3)
Step-by-step explanation:
The variable x can be eliminated by subtracting the first equation from the second.
(x -9y) -(x -12y) = (7) -(-4)
3y = 11 . . . . . . .simpify
y = 11/3 . . . . . .divide by 3
x -9(11/3) = 7 . . . . substitute for y in the second equation
x = 40 . . . . . . . add 33
The solution is (x, y) = (40, 11/3).

find the y-coordinate of the y-intercept of the polynomial function defined below f(x)=2x(x^2+3)
Answer:
y-intercept is (0,0). Mark brainliest?
Answer:
Step-by-step explanation:
2x([tex]x^{2}[/tex] + 3)
when x = 0 then we have a y intercept
2[tex]x^{3}[/tex] +6x
so b/c both terms have an x in them
we know the only time this function hits the y intercept is when y is zero
got it?
answer y = 0

A bird can lay either white or brown eggs. Three white eggs
and
two brown eggs have a mass of 13 grams, while five white eggs
and four brown eggs have a mass of 24 grams. Find the mass
of a brown egg and of a white egg.
Answer:
Mass of brown egg = 3.5 grams
Mass of white egg = 2 grams
Step-by-step explanation:
Let
Mass of brown eggs = x
Mass of white eggs = y
3y + 2x = 13 (1)
5y + 4x = 24 (2)
Multiply (1) by 5 and (2) by 3 to eliminate y
15y + 10x = 65 (3)
15y + 12x = 72 (4)
Subtract (3) from (4)
12x - 10x = 72 - 65
2x = 7
x = 7/2
x = 3.5
Substitute x = 3.5 into (1)
3y + 2x = 13 (1)
3y + 2(3.5) = 13
3y + 7 = 13
3y = 13 - 7
3y = 6
y = 6/3
y = 2
Mass of brown egg = 3.5 grams
Mass of white egg = 2 grams
If two lines have the same y intercept and the same slope will they intercept at exactly one point?
True or false or partly true
Answer:
False because the lines would be going somewhat in this direction // both lines would be like that so they wouldnt intercept unless the lines were to go like /\ then they would intercept

9.17f(x)=4x-3, g(x)=10-x
Work out gf(x)?
Step-by-step explanation:
Given
f(x) = 4x - 3
g(x) = 10 - x
So Now
gf(x) = g( 4x - 3)
= 10 - 4x + 3
= 13 - 4x

Help I need to do that I don’t even know what it is I’ll
Give brianliest
Answer:
Step-by-step explanation:
1. f(x) = 5x² + 3x - 1
a. f(0) = 5·0² + 3·0 - 1 = -1
b. f(-1) = 5(-1)² + 3(-1) - 1 = 1
Do the same for f(2), f(√2), f(a+2), and f(a).
Then do the same thing for the next function.
2. f(x) = x/(1-x)
a. f(0) = 0/(1-0) = 0
Do the same for f(-1), f(2), f(√2), f(a+2), and f(a).

Answer:
Disney The Jungle Book (the first one): Mowgli (played by Neel Sethi) is a young boy that was raised by a family of wolves. One day he has to leave his home when the fearsome tiger, named Shere Khan (voiced by Idris Elba) unleashes a powerful roar.
