Answer:
x= -4
Step-by-step explanation:
Step 1: Simplify
2x-3+3x=-23 turns into
5x-3=-21 -- combined like terms
Step 2: Start Solving
5x-3 = -23
+3 +3 -- Getting x alone by adding 3 to cancel it out
5x = -20
/5 /5 -- getting x alone by dividing by 5 to again cancel it out
Step 3: The answer
x = -4
Answere:
x=-4
Step-by-step explanation:
well, if you have the equation 2x-3+3x=-23, The first thing you wanna do is add up the X's so 2x+3x=5x, and then you put the 5x in the equation instead of 2x+3x:
-3+5x=-23
Then you since you have a -3, you should add 3 on BOTH sides of the equal sighn. And when you add 3 and -23 you get -20, so the new equation is:
5x=-20, from there you can tell X=-4

Caitlyn has a credit card with a spending limit of $1500 and an apr (annual percentage rate) of 18%. during the first month, caitlyn charged $375 and paid $250 of that in her billing cycle. which expression will find the amount of interest caitlyn will be charged after the first month? (0.18) (250 dollars) (0.015) (375 dollars) (0.18) (375 dollars) (0.015) (125 dollars)
The amount of interest Caitlyn will be charged after the first month is $1.875.
Annual percentage rate(APR) of the credit card = 18%
What will be the Monthly Percentage Rate of the credit card?The monthly percentage rate will be 1/12th of APR.
The Amount charged in the first month =$375
Amount paid in billing cycle = $250
So, the amount on which interest will be levied = $375 - $250 = $125
The interest levied on $125 = 125* (18/12)* (1/100)
The interest levied on $125 = $1.875
Therefore, the amount of interest Caitlyn will be charged after the first month is $1.875.

can someone please help me with number 2 and 3? i just have to put them in a sentence
it’s something like this I think
An airline sells all the tickets for a certain route at the same price. If it charges 200 dollars per ticket it sells 10,000 tickets. For every 15 dollars the ticket price is reduced, an extra thousand tickets are sold. This if the tickets are sold for 185 dollars each then 11,000 tickets sell. It costs the airline 100 dollars to fly a person. (a) Express the total profit P in terms of the number n of tickets sold. (b) Express the total profit P in terms of the price p of one ticket.
The function that gives the amount of profit at a given price and number
given are obtained from the relationship between the variables.
a) The profit in terms of the number of tickets sold, P = -0.015·n² + 250·n
(b) The profit in terms of ticket price, is P = -66.[tex]\overline 6[/tex]·p² + 3000·p + 2,333,333.[tex]\overline 3[/tex]
Reasons:
Number of tickets sold at x = $200, is y = 10,000 tickets
Number of extra tickets sold for every $15 price reduction = 1,000 tickets
Number of tickets sold at $185 = 11,000
The cost to fly a person = $100
(a) The rate of change, [tex]\frac{\Delta y}{\Delta x}[/tex], of the number of ticket sold wit price is given as
follows;
[tex]\dfrac{\Delta y}{\Delta x} = \dfrac{11,000 - 10,000}{185 - 200 } = -66. \overline 6[/tex]
The equation in slope and intercept form is therefore;
n - 11,000 = -66.[tex]\overline 6[/tex]·(p - 185)
n = -66.[tex]\overline 6[/tex]·p + 12,333.[tex]\overline 3[/tex] + 11,000 = -66.[tex]\overline 6[/tex]·p + 23,333.[tex]\overline 3[/tex]
Number of tickets sold, n = -66.[tex]\overline 6[/tex]·p + 23,333.[tex]\overline 3[/tex]
[tex]Price \ per \ ticket, \ p = \dfrac{23,333.\overline {3} - n}{66. \overline{6}}[/tex]
The revenue, R = n·x
Therefore;
[tex]R = \dfrac{23,333.\overline {3} \cdot n- n^2}{66. \overline{6}}[/tex]
The profit = Revenue - Cost
The cost = 100·n
[tex]Profit, P = \dfrac{23,333.\overline {3} \cdot n- n^2}{66. \overline{6}} - 100 \cdot n = -0.015 \cdot n^2 + 250 \cdot n[/tex]
Total profit, P = -0.015·n² + 250·n(b) The total profit, P, in terms of the price p, for one ticket
Number of tickets sold, n = -66.[tex]\overline 6[/tex]·p + 23,333.[tex]\overline 3[/tex]
The revenue, R = n·p
∴ R = -66.[tex]\overline 6[/tex]·p² + 23,333.[tex]\overline 3[/tex]·p
Cost = 100·n
∴ Cost = 100·(-66.[tex]\overline 6[/tex]·p + 23,333.[tex]\overline 3[/tex])
Therefore, the profit is given as follows;
Profit = -66.[tex]\overline 6[/tex]·p² + 23,333.[tex]\overline 3[/tex]·p - (100·(-66.[tex]\overline 6[/tex]·p + 23,333.[tex]\overline 3[/tex]))

We want to express the total profit in two different ways.
The answers are:
a) P(n) = n*[n - 23,333.3]*(-15/1,000) - n*100
b) P(p) = n(p)*p - n(p)*100 = [ (-1,000/15)*p + 23,333.3]*(p - 100)
The given information is:
If the ticket price is $200, they sell 10,000 tickets.If the ticket price decreases $15, they sell 1,000 tickets more.It costs $100 to fly a person, then the cost of each ticket is $100.a) We want to get the profit in terms of the number n of tickets sold.
The number of tickets sold depends on the price, we know that it is a linear relation like:
n(p) = a*p + b
where p is the price.
we know that:
n(200) = 10,000
n(185) = 11,000
If this is a linear relation, the slope is known:
a = -1,000/15$
Then the line is something like:
n(p) = (-1,000/15)*p + b
We know that if k = 200, then n = 10,000
Replacing that we have:
n(200) = 10,000 = (-1,000/15)*200 + b
10,000 + (1,000/15)*200 = b = 23,333.3
Then the number of tickets sold as a function of the price is:
n(p) = (-1,000/15)*p + 23,333.3
Then the revenue is given by the number of tickets sold times the price, this is:
r(n) = n*p
We can write k in terms of n as:
k = [n - 23,333.3]*(-15/1,000)
Then the revenue as a function of the number of tickets sold is:
r(n) = n*[n - 23,333.3]*(-15/1,000)
The profit is the difference between the revenue and the cost, then the profit function is:
P(n) = n*[n - 23,333.3]*(-15/1,000) - n*100
Where n*100 is the cost.
b) now we want to write the same equation, but this time as a function of the price.
now the revenue is:
r(p) = n*p = [ (-1,000/15)*p + 23,333.3]*p
Then the profit is:
P(p) = n(p)*p - n(p)*100 = [ (-1,000/15)*p + 23,333.3]*(p - 100)

what is the property of equality of 2y − 40 = -18?
Answer:
Given the equation 2y-40=-18 to simplify the equation further we need to first add 40 to both sides of the equation thereby justifying the addition property as shown;
2y-40 + 40 =-18+40
2y = 40-18
2y = 22
We will also apply the division property here. Division property is used when both sides of an equation is divided by a number without affecting the equality rule.
Dividing the resulting equation by 2:
2y/2 = 22/2
y = 11

PLEASE HELP! WILL CROWN!! I need statements and reasons on DC and EF!!! plzzz
Answer:
DC⊥EF as the 2 angles in smallest triangle are 30 and 60 degrees, so the last one is 90 making Line DC perpendicular to Line EF.
Step-by-step explanation:
DC⊥EF means that Line DC is perpendicular (90 degrees) to EF.
To prove this, we can use the two angles of the small triangle created by the intersection of the triangles AEF and DCB.
The remaining angle of triangle AEF is 60, as all angles of triangles add up to 180 (so 180 - 12 = 60). This angle at F is shared with the little triangle.
Now we will get the angle at D using the triangle DCB. Since we are given two angles 90 and 60, angle D has to be 30.
So of our little triangle, we have angles 30 and 60, meaning the last one is 90 degrees and hence, DC⊥EF
