Enter the x coordinate of the solution to this system of equations.
- 2x + y = 5
– 5x + y = – 4
Answer:
x = 3
Step-by-step explanation:
Given the 2 equations
- 2x + y = 5 → (1)
- 5x + y = - 4 → (2)
Multiply (2) by - 1 then add to (1) to eliminate y
5x - y = 4 → (3)
Add (1) and (3) term by term to eliminate y
3x = 9 ( divide both sides by 3 )
x = 3
A plane leaves London where the tempretaure outside is 17 C.
The plane rises to a height where the tempreture outside is -43 C.
The tempreture decreases by 2 C with every increase of 300 m in height.
The maximum height of plane is
Answer:
First you find the difference in temperature. Final temperature minus initial temperature. -43-17=-60 So for every 300m temp will minus 2C.
There's a difference of -60, how many -2 is in -60? So -60÷(-2)= 30. 30 times 300m = 9000m or 9km.
Multiply: (√2x^3 +√12x)(2√10x^5 + √6x^2)

A florist currently makes a profit of $20 on each of her celebration bouquets and sells an average of 30 bouquets every week. She noticed that when she reduces the price such that she earns $1 less in profit from each bouquet, she then sells three more bouquets per week. The relationship between her weekly profit, P(x), after x one-dollar decreases is shown in the graph below.
Use the graph to complete each statement about this situation.
The maximum profit the florist will earn from selling celebration bouquets is $___.
The florist will break-even after___one-dollar decreases.
The interval of the number of one-dollar decreases for which the florist makes a profit from celebration bouquets is (__,__).
Given : A florist currently makes a profit of $20 on each of her celebration bouquets and sells an average of 30 bouquets every week . and graph
To Find : Maximum profit , breakeven point , profit interval
Solution:
The maximum profit the florist will earn from selling celebration bouquets is $ 675
peak of y from Graph
The florist will break-even after Selling 20 one-dollar decreases.

Enjal paid Rs 15,255 for smart phone with 10% discount and 13% vat. Find marked price of that smart phone.
Answer:
The marked price of the smart phone is Rs 15,000.
Step-by-step explanation:
We proceed to explain step by step how to determine the marked price of the smart phone:
1) Divide the resulting price by the VAR factor:
[tex]C' = \frac{C''}{1 + \frac{r}{100} }[/tex] (1)
Where:
[tex]C''[/tex] - Resulting price, measured in rupees.
[tex]C'[/tex] - Price of the product after discount, measured in rupees.
[tex]r[/tex] - VAT rate, measured in percentage.
If we know that [tex]C'' = 15,255\,INR[/tex] and [tex]r = 13[/tex], then the price of the product after discount is:
[tex]C' = \frac{15,255\,INR}{1+\frac{13}{100} }[/tex]
[tex]C' = 13,500\,INR[/tex]
2) Divide the price of the product after discount by the discount factor:
[tex]C = \frac{C'}{1-\frac{r'}{100} }[/tex] (2)
Where:
[tex]C[/tex] - Marked price of the product, measured in rupees.
[tex]r'[/tex] - Discount rate, measured in percentage.
If we know that [tex]C' = 13,500\,INR[/tex] and [tex]r' = 10[/tex], then the marked price of the product is:
[tex]C = \frac{13,500\,INR}{1-\frac{10}{100} }[/tex]
[tex]C = 15,000\,INR[/tex]
The marked price of the smart phone is Rs 15,000.

cosine of pi divided by three times cosine of pi divided by five plus sine of pi divided by three times sine of pi divided by five.
Answer:
cos(π/3)cos(π/5) + sin(π/3)sin(π/5) = cos(2π/15)
Step-by-step explanation:
We will make use of trig identities to solve this. Here are some common trig identities.
Cos (A + B) = cosAcosB – sinAsinB
Cos (A – B) = cosAcosB + sinAsinB
Sin (A + B) = sinAcosB + sinBcosA
Sin (A – B) = sinAcosB – sinBcosA
Given cos(π/3)cos(π/5) + sin(π/3)sin(π/5) if we let A = π/3 and B = π/5, it reduces to
cosAcosB + sinAsinB and we know that
cosAcosB + sinAsinB = cos(A – B). Therefore,
cos(π/3)cos(π/5) + sin(π/3)sin(π/5) = cos(π/3 – π/5) = cos(2π/15)

Answer:
3
Step-by-step explanation:
"Find a number which, when added to 3, yields 7"
may be written as:
3 + ? = 7, 3 + n = 7, 3 + x = 1
and so on, where the symbols ?, n, and x represent the number we want to find. We call such shorthand versions of stated problems equations, or symbolic sentences. Equations such as x + 3 = 7 are first-degree equations, since the variable has an exponent of 1. The terms to the left of an equals sign make up the left-hand member of the equation; those to the right make up the right-hand member. Thus, in the equation x + 3 = 7, the left-hand member is x + 3 and the right-hand member is 7.
SOLVING EQUATIONS
Equations may be true or false, just as word sentences may be true or false. The equation:
3 + x = 7
will be false if any number except 4 is substituted for the variable. The value of the variable for which the equation is true (4 in this example) is called the solution of the equation. We can determine whether or not a given number is a solution of a given equation by substituting the number in place of the variable and determining the truth or falsity of the result.
Example 1 Determine if the value 3 is a solution of the equation
4x - 2 = 3x + 1
Solution We substitute the value 3 for x in the equation and see if the left-hand member equals the right-hand member.

Marcy needs to make 5 lb of a cashew/raisin mixture for a party. Her local grocery store sells raisins for $4.50/lb and cashews for $9.50/lb. How many pounds of raisins and cashews should she buy if she wants to spend $40? Enter your answers in the boxes. raisins: lb cashews: lb
Answer:
Pounds of raisins = 1.5 lb
Pounds of cashew = 3.5 lb
Step-by-step explanation:
Let
Pounds of raisins = x
Pounds of cashew = y
x + y = 5 (1)
4.50x + 9.50y = 40 (2)
From (1)
x = 5 - y
Substitute x = 5 - y into
4.50x + 9.50y = 40
4.50(5 - y) + 9.50y = 40
22.50 - 4.50y + 9.50y = 40
- 4.50y + 9.50y = 40 - 22.50
5y = 17.5
y = 17.5 / 5
= 3.5
y = 3.5lb
Substitute y = 3.5 into
x + y = 5
x + 3.5 = 5
x = 5 - 3.5
= 1.5
x = 1.5lb
Pounds of raisins = 1.5 lb
Pounds of cashew = 3.5 lb

The principal amount, $5500, earns 3.75% interest compounded continuously.
a. Write the function that represents the value of the account at any time, t.
b. What will the value be after 6 years?
Answer:
a)
The function that represents the value of the account at any time, t
[tex]\:\:A=Pe^{rt}[/tex]
b)
The total amount accrued, principal plus interest, from compound interest on an original principal of $ 5,500.00 at a rate of 3.75% per year compounded continuously over 6 years is $ 6,887.77.
Step-by-step explanation:
a. Write the function that represents the value of the account at any time, t.
The function that represents the value of the account at any time, t
[tex]\:\:A=Pe^{rt}[/tex]
where
A represents the Future Value
P represents the Principle (Initial Value)
r represents the Interest rate
t represents the time
b) What will the value be after 6 years?
Given
The principal amount P = $5500
Annual Rate r = 3.75% = 3.75/100 = 0.0375
Time Period t = 6 years
To Determine:
The total amount A = ?
Using the formula
[tex]\:\:A=Pe^{rt}[/tex]
substituting the values
[tex]A\:=\:5500\left(2.71828\right)^{\left(0.0375\right)\left(6\right)}[/tex]
[tex]A=5500\cdot \:2.71828^{0.225}[/tex]
[tex]A = $ 6,887.77[/tex] $
Therefore, the total amount accrued, principal plus interest, from compound interest on an original principal of $ 5,500.00 at a rate of 3.75% per year compounded continuously over 6 years is $ 6,887.77.

The bids in an online auction are represented by the arithmetic sequence shown below: right on explicit formula to represent the bids as an arithmetic sequence. What is the tenth bid
Answer:
10th bid is 292
Step-by-step explanation:
Here, as we can see, we have an arithmetic sequence and we want to calculate its 10th term
From the question, we can see that the first term a is 193
The common difference is 204-193 = 11
The formula for the nth term of a sequence is;
a + (n-1)d
In this case, n = 10
so we have ;
193 + (10-1)11
= 193 + 99 = 292

Step-by-step explanation:
Jean drove 64 miles per hour for a total of 448 miles on a trip. She used the equation below to calculate the time, t, it would take her to complete the trip.
Answer:
Step-by-step explanation:
since there is no given formula I'm guessing that's what we want to find?
use the dist. = rate * time formula for this kind of problem
or d = r*t ( this looks like the word "dirt" to me so I call this the dirt formula partly b/c it's dirt simple, and it's generally about moving across some give dist. of dirt :P )
so Jean's rate is 64 MPH
her total distance is 448 miles
rearrange the d = rt formula so that you are solving for the thing you don't know.. yet.... t (time) for this case
soooo...
d/r = t
plug in number
448 / 64 = t
7 = t (in hours)
