M is the midpoint of line segment LN. Find the length of LN
Answer:
Step-by-step explanation:
Here is the complete question;
M is the midpoint of line segment LN. If LM= 3x + 5 and LN= 5x + 40, find the length of LN.
Since M is the midpoint of LN, hence LM + MN = LN and LM = MN
LM + LM = LN
2LM = LN ..... *
Given;
LM= 3x + 5
LN= 5x + 40
Substitute into the eqn *
2(3x+5) = 5x+40
6x+10 = 5x+40
6x-5x = 40-10
x = 30
Get the length LN
LN= 5x + 40
LN = 5(30)+40
LN = 150+40
LN = 190
Hence the length of LN is 190
Answer:
190

The list of ordered pairs below represents a function
(12, 6), (3, 1), (2,-2), (5, 10), (-8, -4) (_,_)
Which of the following could be the missing ordered pair?
A. (2,1)
B. (12,7)
C. (-8,8)
D. (-3,-4)
Answer:
D. (-3,-4)Step-by-step explanation:
GivenOrdered pairs
(12, 6), (3, 1), (2,-2), (5, 10), (-8, -4) (_,_) To findThe missing pairSolutionSince it is a function, the missing pair can't repeat input values with different output, therefore only option D is unique so is the correct choice
1. Explain how a function may be reflected about the x-axis.
2. Explainhowafunctionmaybereflectedaboutthey-axis.
3. What is the difference between a slope change and a translation?
Answer:
If the function is reflected across the x-axis, the negative sign will be like this -f(x)
If the function is reflected across the y-axis, it will be lie this f(-x)
Translation is the movement of an object without any change of size, whereas change of slope is the difference in steepness.

Factor the expression completely. 5 - 45x^5
Answer:
5(9x-5)
Step-by-step explanation:
9x^2-4
F.(3x + 2)(3x - 2)
G.(3x + 2)2
H. (3x - 2)2
J.prime
Answer:
Step-by-step explanation:
I'm not entirely sure what the question is, but I suspect the answer is not prime.
9x^2 - 4
factors into two factors (3x + 2)(3x - 2)
Suppose x = 11 which is prime.
9*121 - 4
1085 which ends in a 5 so the expression is not prime.
In fact, the two factors are 3*11 + 2 = 35 and 3*11 - 2 = 31
31*35 = 1085
9514 1404 393
Answer:
F. (3x +2)(3x -2)
Step-by-step explanation:
The given expression is the difference of two squares, so can be factored accordingly.
9x^2 -4 = (3x)^2 -2^2 = (3x +2)(3x -2) . . . . . matches F
Three students have started a fence-painting business. Working together,
Pragnesh and Qazi can paint the fence in 2 hours. Similarly, Pragnesh and Ronghui can paint the
fence in 3 hours when they work together. Finally, when Qazi and Ronghui work together, they can
paint the fence in 4 hours. How long would it take if all three students worked together to paint the
Answer:
4 1/2 hours
Step-by-step explanation:
Pragnesh = 30 minutes
Qazi = 1 1/2 hours
Ronghui = 2 1/2 hours
add them and that gets you 4 1/2 hours. You can also check this yourself by putting this in the number problem. :)

In a three-digit number, the tens digit is the same as the hundreds digit. The ones digit of this number is equal to 1/3 of the sum of the other two digits. Find the number if the sum of all its digit is equal to 24.
Answer:
996
Step-by-step explanation:
the three digit number is;
996
Step-by-step explanation:
The three digit can be written xyz
ones digit is equal to 1/3 the sum of the two other digits
z = 1/3(x + y)
x + y + z = 24
Tens digit is same as hundreds digit
That means x = y
z = 1/3 (x + x) = 2x/3
So;
2x/3 + x + x = 24
Multiply through by 3
2x + 3(2x) = 72
8x = 72
x = 72/8
x = 9
x = y = 9
z = 1/3(18)
z = 6

Farmer Jones wants to make a circular corral for his horses. If the diameter is to be 500 m,
how many meters of fencing is needed? Round to the nearest whole number? Use 3.14 for .
Answer:
1571mStep-by-step explanation:
Step one:
given data
the diameter of the farm= 500m
the radius will be d/2
= 500/2
r=250m
Step two:
Required
The perimeter fence for the farm
this is also the same as the circumference of the farm
C=2πr
C=2*3.142*250
C=1571m
Hence the needed length of fence is 1571m

Use the graph to fill in the blank with the correct number.
f(-2)=?
Answer:
2
Step-by-step explanation:
In function notation, f(x) equals the y value and the x equals the x value. So this question is asking you to find the value of y when x=-2. To do this find -2 on the graph and find the point with the same x value, then find what value of y it is on. In this case, f(-2)=2.

Answer:
23
Step-by-step explanation:
First, we can rearrange the equation to make it look simpler.
2+y+11 ---->
y+2+11
Then, we can combine like terms, thus
y+13
Then, we can plug in 10 for y
(10)+13
Combine like terms again, and the answer is:

Answer:
she charges 20 dollars per photo
for every photo it goes up by 20. you could say that the slope is 20 also.
Answer:
She charges 20 dollars per photo
Step-by-step explanation:
Pick any price on the y axis and divide by the corresponding x-value. For example, the line has a point at (60,3) so we can divide 60 by 3 to give us 20. 20 is therefore the slope of the line.

A game is played using ne die. If the die is rolled and shows 3, the player wins $45. If the die shows any number other than 3, the player wins nothing. If there is a charge of $9 to play the game, what is the game's expected value?
Answer:
-$13.5
Step-by-step explanation:
Let x be a random variable of a count of player gain.
- We are told that if the die shows 3, the player wins $45.
- there is a charge of $9 to play the game
If he wins, he gains; 45 - 9 = $36
If he looses, he has a net gain which is a loss = -$9
Thus, the x-values are; (36, -9)
Probability of getting a 3 which is a win is P(X) = 1/6 since there are 6 numbers on the dice and probability of getting any other number is P(X) = 5/6
Thus;
E(X) = Σ(x•P(X)) = (1/6)(36) + (5/6)(-9)
E(X) = (1/6)(36 - (5 × 9))
E(X) = (1/6)(36 - 45)
E(X) = -9/6 = -3/2
E(X) = -3/2
This represents -3/2 of $9 = -(3/2) × 9 = - 27/2 = -$13.5
Find the mean of 3, 11, 6, 13, 14
Answer:
9.4
Step-by-step explanation:
To find the mean, add the values up and then divide them by the number of values there are:
3 + 11 + 6 + 13 + 14 = 47
47/5 = 9.4
The mean is 9.4

If DG = 60ft, solve for GO
35
7
None of the other answers are correct
25
6
Answer:
A: 35
Step-by-step explanation:
DG is the combined segments DO and OG. In other words:
[tex]DG=DO+OG[/tex]
We know that DG is 60. DO is (4x-3) and OG is (2x+21). So, substitute:
[tex]60=(4x-3)+(2x+21)[/tex]
Solve for x. Combine like terms:
[tex]60=6x+18[/tex]
Subtract 18 from both sides:
[tex]42=6x[/tex]
Divide both sides by 6. Hence, the value of x is:
[tex]x=7[/tex]
GO is defined as (2x+21).
So, to find GO, we can now substitute 7 for x and evaluate. Therefore:
[tex]GO=2(7)+21=14+21=35[/tex]
Hence, our answer is A.
