Answer:
-11x+6
Step-by-step explanation:
Answer:
x=6/11
Step-by-step explanation:
2(- 3х + 4) = 5х + 2
(- 6х + 8) = 5х + 2
+6x +6x
8=11x+2
-2 -2
6=11x
6/11=11x/11
6/11=x
Graph the line that passes through the points ( 0 , − 4) and (−5,2) and determine the equation of the line.
i am highly sorry but there is no graph for me to help you with on this site :(
but to help you the X line always comes first for example the (-5,2) the -5 would be on the X line. I really hope that this help. :)
Hailey wants to brighten up her front yard by adding some flowers. She decides on zinnias and marigolds. She wants more than 3 trays of marigolds, which cost $12.00 each, and at least 5 trays of zinnias, which cost $10.00 each. How many of each can she buy if she has a budget of $150.00? Let the number of zinnias = and the number of marigolds = .
Answer:
5 Marigolds and 9 Zinnias
Step-by-step explanation:
5x12=60
9×10=90
90+60=150
So that is your answer
Hailey can buy at least 5 trays of marigolds and 9 trays of zinnias with a budget of $150.00.
Let's solve the problem step by step. Let the number of trays of zinnias that Hailey buys be represented by the variable 'Z', and the number of trays of marigolds be represented by the variable 'M'.
Each tray of marigolds costs $12.00, so the total cost of the marigolds would be 12M. Hailey wants more than 3 trays of marigolds, so M > 3.
Similarly, each tray of zinnias costs $10.00, so the total cost of the zinnias would be 10Z. Hailey wants at least 5 trays of zinnias, so Z ≥ 5.
Hailey has a budget of $150.00, so the total cost of the flowers cannot exceed $150.00. Therefore, we can write the following inequality:
12M + 10Z ≤ 150
To find the possible values of M and Z that satisfy the given conditions, we can use trial and error or a systematic approach. Let's check a few values that satisfy the given conditions:
For M = 4 and Z = 5:
12(4) + 10(5) = 48 + 50 = 98, which is less than $150.00, so this is a valid solution.
For M = 5 and Z = 9:
12(5) + 10(9) = 60 + 90 = 150, which is equal to $150.00, so this is also a valid solution.
Other possible combinations could be M = 6 and Z = 5, M = 6 and Z = 6, and so on.

Bridgette has $1,000 to invest. She has two different investment options, shown in the table below. Each option would give her a different value over three years.
Number of Years 1 2 3
Option A (amount in dollars) 1100 1200 1300
Option B (amount in dollars) 1100 1210 1331
Part A: What type of function, linear or exponential, would be best to describe the value of the investment over a fixed number of years using Option A? Explain your answer.
Part B: Write a function, a(t), to describe the value of the investment, in dollars, of Option A after t years.
Part C: What type of function, linear or exponential, would be best to describe the value of the investment over a fixed number of years using Option B? Explain your answer.
Part D: Write a function, b(t), to describe the value of the investment, in dollars, of Option B after t years.
Part E: Bridgette wants to invest in whichever option would increase her investment value by the greatest amount in 20 years. Will there be any significant difference in the value of Bridgette's investment after 20 years if she uses Option A over Option B? Explain your answer, and show the investment value after 20 years for each option.
Answer:
Part A:
Option A is a linear function
Part B:
a(t) = t × 100 + 1000
Part C:
Option B is an exponential function
Part D
[tex]b(t) = 1000 \times (1 + 0.1)^t[/tex]
Part E:
There will be a significant difference in the value of Bridget's investment after 20 yeas if she uses Option A over Option B
Step-by-step explanation:
The given parameters are;
The amount Bridgette has to invest = $1,000
The value of each investment option is given as follows;
Number of years [tex]{}[/tex] Option A [tex]{}[/tex] Option B
1 [tex]{}[/tex] 1100 1100
2 [tex]{}[/tex] 1200 1210
3 [tex]{}[/tex] 1300 1331
Part A:
Given that the first difference between subsequent data values are 2 - 1 = 1 and 1200 - 1100 = 100, 3 - 2 = 1 and 1300 - 1200 = 100 both of which are constant, the type of function that would be best to describe option A is a linear function
Part B:
The function a(t) for Option A is given as follows;
The rate of change of the function amount with time is (1300 - 1200)/(3 - 2) = 100
Therefore, comparing with the general form of a linear function, y = m·x + c, we have;
m = The rate of change of the function = 100
The y-intercept, the value of the amount a 0 time (the start of the investment) = c = 1000
The function in terms of t, a(t) = t × 100 + 1000
Part C:
The first difference of Option B are different but the first ratio given as follows;
1210/1100 = 1331/1210 = 1.1 = Constant which is the characteristics of an exponential variable
Therefore, the equation to describe the value of the investment in dollars, of Option B is an exponential function
Part D
We, have for an exponential function;
[tex]b(t) = 1000 \times (1 + r)^t[/tex]
When t = 1, we have;
[tex]b(1) = 1000 \times (1 + r)^1 = 1100[/tex]
∴ 1 + r = 1100/1000 = 1.1
r = 1.1 - 1 = 0.1
We check for t = 2, to get;
[tex]a(2) = 1000 \times (1 + 0.1)^2 = 1210[/tex]
We check for t = 3, to get;
[tex]b(3) = 1000 \times (1 + 0.1)^3 = 1331[/tex]
The function b(t) to describe the value of the investment in dollars, of Option B after t years is [tex]b(t) = 1000 \times (1 + 0.1)^t[/tex]
Part E:
The investment value after 20 years is given as follows;
For Option A, we have;
a(20) = 20 × 100 + 1000 = 3000
For Option B, we have;
[tex]b(20) = 1000 \times (1 + 0.1)^{20} \approx 6727.5[/tex]
Therefore, the difference in the investment value after 20 years for Option B and Option A is approximately $6727.5 - $3000 = $3727.5 which is significant.

Your parents gave you $20 to spend at the book fair. You are getting the new Diary of the Wimpy kid book that costs $8.99/ If pencils and erasers cost $0.79 each, what is the maximum you can buy with the money provided?
Answer:
You can buy a maximum of 13 erasers/pencils.
Step-by-step explanation:
Your total is 20 dollars. The book cost 8.99, so you take away that amount from 20, getting you 11.01. You have $11.01 left. Then you divide your total (11.01) by the price of each eraser (0.79). This gets you 13.9367088608. Since thats not an even number, you have to round down because you don't want a broken pencil?eraser.

Least common denominator of 9/4 and 5/6
Answer:
12
Step-by-step explanation:
We want the smallest possible number that can be divided by both 4 and 6 with no remainders.
12 is the least common multiple (LCM) of both 4 and 6, meaning it's the smallest number that 4 and 6 both divide into evenly.
24 could be used as a common denominator, but it isn't the least common denominator. It has more prime factors than is necessary to be the LCD.
12, when its prime factorization is written out, is 2² • 3.
24, when its prime factorization is written out, is 2³ • 3.
9/4 → (9•3)/(4•3) → 27/12
5/6 → (5•2)/(6•2) → 10/12
Write 8 1/3 as a proper fraction
Answer:
divde 81/3 to find 27
Step-by-step explanation:
The mixed fraction 8( 1/3 ) in the form of the proper fraction will be ( 25 / 3 ).
What is a fraction?Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction can also be an ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
A mixed fraction is one that has both a quotient and a remainder. A mixed fraction is, for instance, 2 1/3, where 2 is the quotient and 1 is the remainder.
Given mixed fraction is 8 ( 1 / 3 ). The fraction will be solved by multiplying the whole number with the denominator and adding the numerator.
8 ( 1/3 ) = ( 24 + 1 ) / 3
8 ( 1/3 ) = ( 25 ) / 3
Therefore, the mixed fraction 8( 1/3 ) in the form of the proper fraction will be ( 25 / 3 ).

Answer:
2 x ? = 7 1/2 and ? x 2 = 7 1/2
Step-by-step explanation:
This is the answer because it didn't show the answer so all you have to figure out is the multiplication problem that goes with the division problem. So 2 x ? = 7 1/2 and ? x 2 = 7 1/2 you don't have to include the answer all you have to include is where the answer will do if you DID have the answer. These two are correct because the multiplication number can go in any order.

Step-by-step explanation:
The ratio 68:84 in its simpliest form is;
68:84 (Since it can divided by 2 perfectly);
34:42 (We also divide this by 2 )
17:21
17:21 is the final answer and it can be divide any further. Since 17 is a prime number, it can't be divided and also 21 can be divided by 3 but 17 can't be divided by 3 so we leave the final answer like that.
