What are the coordinates of the point on the directed line segment from
(-4,-9) to (1, 1) that partitions the segment into a ratio of 3 to 2?
Answers
Answer:
(- 1, - 3 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) partitioned in the ratio m : n
Then using the Section formula the coordinates of the point are
( [tex]\frac{nx_{1}+mx_{2} }{m+n}[/tex], [tex]\frac{ny_{1}+my_{2} }{m+n}[/tex] )
Here (x₁, y₁ ) = (- 4, - 9), (x₂, y₂ ) = (1, 1) and m : n = 3 : 2 , then
( [tex]\frac{2(-4)+3(1)}{3+2}[/tex] , [tex]\frac{2(-9)+3(1)}{3+2}[/tex] )
= ( [tex]\frac{x}{y} \frac{-8+3}{5}[/tex], [tex]\frac{-18+3}{5}[/tex] )
= ( [tex]\frac{-5}{5}[/tex], [tex]\frac{-15}{5}[/tex] )
= ( - 1, - 3 )

A subway ride for a student costs $1.25. A monthly pass costs $35.
a. Write an inequality that represents the number of times you must ride the
subway for the monthly pass to be a better deal.
b. You ride the subway about 45 times per month. Should you buy the monthly
pass? Explain.
Answers
A: 29 times
B: Yes
Explanations:
A: You do 35/1.25 and get 28, but thats not a better deal that's the same, so you go up one and make it 29.
B: Yes, 45(1.25) is 56.25 which is well over 35
Answer:
a. x(1.25) > $35
b. 45(1.25) = 56.25. Yes you should buy the monthly pass opposed to paying $1.25 each time you ride the subway.
Step-by-step explanation:
a. x = (number of subway rides) 1.25 = (cost per subway ride)
> = the cost of paying individual subway rides surpasses the cost of the monthly pass therefore making it a better deal.
b. If you ride the subway 45 times, 45 x 1.25 = 56.25 which is $21.25 more than the $35 monthly subway pass, which makes the monthly pass more practical.
Juelle had $25,000 to invest. She invested part of that amount at 3% interest and part at 5% interest for one year. The amount of interest she earned for both investments was $1100. How much was invested at each rate?
Answers
Answer:
The first amount invested at 3%= x = $7500
The second amount Invested at 5% = y = $17500
Step-by-step explanation:
Juelle had $25,000 to invest.
She invested part of that amount at 3% interest and part at 5% interest for one year.
The amount of interest she earned for both investments was $1100.
The formula for Simple Interest =
Principal × Rate × Time
Let us represent
The first amount invested at 3%= x
The second amount Invested at 5% = y
x + y= $25,000....... Equation 1
x = 25,000 - y
3% × x + 5% × y = $1100...... Equation 2
0.03x + 0.05y = 1100...... Equation 2
We substitute 25000 - y for x in Equation 2
0.03x + 0.05y = 1100
0.03(25000 - y) + 0.05y = 1100
750 - 0.03y + 0.05y = 1100
Collect like terms
- 0.03y + 0.05y = 1100 - 750
0.02y = 350
y = 350/0.02
y = 17500
Solving for x
x = 25,000 - y
x = 25000 - 17500
x = 7500
Therefore:
The first amount invested at 3%= x = $7500
The second amount Invested at 5% = y = $17500

A clothing company charges a 15% shipping fee on orders under $50 and a 12.5% shipping charge on orders of $50 or more. How much more would the company charge for shipping on a $49 order than on a $50 order? *
Answers
Answer:
$1.10
Step-by-step explanation:
order of $49 would result in a $7.35 shipping charge (49 x .15)
order of $50 would result in a $6.25 shipping charge (50 x .125)
difference is $1.10
The company will charge $1.1 for shipping on a $49 order than on a $50 order.
What is equation modelling? What is a mathematical equation and expression? Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is a clothing company charges a 15% shipping fee on orders under $50 and a 12.5% shipping charge on orders of $50 or more.
Now, for $49, the shipping charge will be -
[x] = 15% of 49
[x] = (15/100) x 49
[x] = 7.35
now -
[y] = 12.5% of 50
[y] = (12.5/100) x 50
[y] = 6.25
Now -
[x] - [y] = 7.35 - 6.25 = $1.1
Therefore, the company will charge $1.1 for shipping on a $49 order than on a $50 order.

2 questions,Neeed helpppp assssaaaappp!!!
Answers
Answer:
(i) (x + 3) is a factor of p(x)= x⁴ + 4x³ + 4x² + 4x + 3 and the remaining factors are (x + 1) and ( x² + 1).
(ii) (x + 1) is not a factor of p(x)= 2x⁴ - 5x² - 2 and the remainder is -5.
Step-by-step explanation:
(i) Given;
Polynomial, p(x)= x⁴ + 4x³ + 4x² + 4x + 3
Factor, = x + 3
x = -3
if (x + 3) is a factor of the polynomial, then p(-3) = 0
p(-3) = (-3)⁴ + 4(-3)³ + 4(-3)² + 4(-3) + 3
= 81 -108 + 36 - 12 + 3
= 0
(x + 3) is a factor of the given polynomial and the remainder is 0.
The remaining factors can be obtained as follows;
x³ + x² + x + 1
--------------------------------
x + 3 √x⁴ + 4x³ + 4x² + 4x + 3
- ( x⁴ + 3x³)
--------------------------------
x³ + 4x² + 4x + 3
-(x³ + 3x²)
----------------------------------
x² + 4x + 3
-(x² + 3x)
---------------------------------------
x + 3
-(x + 3)
---------------------------------------
0
Further divide x³ + x² + x + 1 by x + 1
x² + 1
---------------------
x + 1 √x³ + x² + x + 1
-(x³ + x²)
------------------------
x + 1
-( x + 1)
-----------------
0
Thus, the factors of x⁴ + 4x³ + 4x² + 4x + 3 = (x + 3)(x + 1)( x² + 1)
(ii) Given;
Polynomial, p(x)= 2x⁴ - 5x² - 2
Factor, = x + 1
x = -1
if (x + 1) is a factor of the polynomial, then p(-1) = 0
p(-1) = 2(-1)⁴ - 5(-1)² - 2
= 2 - 5 - 2
= -5
Thus, (x + 1) is not a factor of the given polynomial and the remainder is -5.

1) Solve the following equations : a)x/5 + 10 =15 b) 25x + 26 = 101
2) Four less than a number is 10 . b)The product of three and a number equals 12
Answers
Answer:
1a) 25, 1b) 3, 2a) 14, 2b) 4
Step-by-step explanation:
1a)
x/5 + 10 = 15
Subtract 10 from both sides:
x/5 = 15 - 10
x/5 = 5
Multiply both sides by 5:
x = 5 * 5
x = 25
1b)
25x + 26 = 101
Subtract 26 from both sides:
25x = 101 - 26
25x = 75
Divide both sides by 25:
x = 75/25
x = 3
2a)
Four less than a number is 10.
Let's call the number x. This means:
x - 4 = 10
Now add 4 to both sides:
x = 10 + 4
x = 14
2b)
The product of three and a number equals 12.
Let's call the number x. This means:
3 * x = 12
Now divide both sides by 3:
x = 12/3
x = 4
