Answer:
12. 3:12
Step-by-step explanation:
that is 12
Answer:
Let's define the variables:
A = price of one adult ticket.
S = price of one student ticket.
We know that:
"On the first day of ticket sales the school sold 1 adult ticket and 6 student tickets for a total of $69."
1*A + 6*S = $69
"The school took in $150 on the second day by selling 7 adult tickets and student tickets"
7*A + 7*S = $150
Then we have a system of equations:
A + 6*S = $69
7*A + 7*S = $150.
To solve this, we should start by isolating one variable in one of the equations, let's isolate A in the first equation:
A = $69 - 6*S
Now let's replace this in the other equation:
7*($69 - 6*S) + 7*S = $150
Now we can solve this for S.
$483 - 42*S + 7*S = $150
$483 - 35*S = $150
$483 - $150 = 35*S
$333 = 35*S
$333/35 = S
$9.51 = S
That we could round to $9.50
That is the price of one student ticket.
Answer:
-3 < x ≤ 13
Step-by-step explanation:
the filled circle is the less/greater than or equal to sign and the open circle is a less/greater than sign.
The correct answer is a.
Inside the function it says x+2, and a +2 means it is to the left (direction is opposite of the sign)
The 3 on the outside of the function shows how the steepness, or slope will change. The first is correct because slope is rise over run, and if you go from one point to another, you'll see that it is up 3 and over 1, or 3/1, or 3.
