E^2x - e^x -56 =0
(E^x - 8) (e^x + 7) = 0
E^x - 8 = 0
E^x +7 = 0
X = ln8 or x = 2.07944154...
(I) The 15 represents the money earned for each ticket sold
In other words the 15 is the cost of each ticket.
(II) The 700 represents the costs inquired when organizing the dance
In other words...how much it costs to throw the dance.
<u>Explanation</u>
Since t is the number of tickets and the function shows profit we know that every step on the left has some aspect to do with the profit....for ever ticket (t) sold there is an addition of 15 dollars...or for every 1 ticket sold $15 is earned....or each ticket costs 15 dollars
The -700 shows that 700 dollars must be subtracted from the total income from selling tickets....since this is looking for profit which is income-costs and we have already determined that 15t represents the income we know that the 700 must represent the costs of throwing the dance.
Answer:
I got -8m+24-32n
Step-by-step explanation:
8 and m equals 8m and since its negative 8 you add a negative sign: -8m
A negative and a negative equals a positive so its a positive sign and it equals +24:+24
A negative and a positive equals a negative so its minus 32n since the 4 includes an n:-32m
Hello,
answer D (-2,3)
Indeed
y=4x+11
y=-2x-1
==>4x+11=-2x-1
==>6x=-12
==>x=-2
And y=4*(-2)+11=3
For this case we must simplify the following expression:
Simplifying the numerator, dividing all the terms by 4, we have:
We factor by looking for two numbers that when added together give -8 and when multiplied by 12. These are: -6 and -2
So, we have to:
Simplifying the denominator:
We rewrite -17x as -18x + x:
We factor the highest common denominator of each group:
We factor the polynomial by factoring the highest common denominator (x-6):
So, we have to:
Substituting in the original expression we have:
