Step-by-step Answer:
What is the solution to the system of equations?
y = –3x – 2 ..............(1)
5x + 2y = 15..............(2)
Substitute (1) in (2) to give
5x + 2(-3x-2) = 15
5x-6x-4 = 15
-x-4=15
solve for x:
-4-15 = x
x=-19
Now substitute x=-19 into equation (1)
y = -3x-2 = 57-2 = 55
Therefore the solution is (-19, 55)
Answer:
1.2761445e+16
Step-by-step explanation:
8*48=384/7"16=1.2761445e+16
X = number of tickets sold in advance, and thus cheaper.
x + 206 = number of tickets sold at the door.
now, the ones sold at the door, are more expensive and is more than the early sold tickets, as you know is x + 206.
now, if the early ones cost each one 6 bucks, then the cost for all of them is 6*x, or 6x.
the ones sold at the door are 10 bucks each, and therefore their total cost is 10(x + 206).
now, we know sales in total for both was 6828, therefore,
and surely you'd know what that is.
how many were sold at the door? well, x + 206.
I believe there is a 1/20 chance that Mrs. Galvan will pick a black pin. Since there are 20 pens, each pen has an equal chance of getting picked. For example, you have 2 pens and one of them is blue. The chance of me getting the blue pen is 1/2 or a 50% chance. So your answer will be 1/20 chance.
Answer:
2
Step-by-step explanation:
We can find the slope between two points by using
m= (y2-y1)/(x2-x1)
= (3 - -3)/(0 - -3)
= (3+3)/(0+3)
= 6/3
