Answer:
x/2 +14
Step-by-step explanation:
X=number of senior tickets
y=number of student tickets
1st day
7x+1y=101
2nd day
7x+12y=134
easy, we can eliminate the x's
multiply first equation by -1
-7x-1y=-101
<u>7x+12y=134 +</u>
0x+11y=33
11y=33
divide by 11 both sides
y=3
sub back
7x+y=101
7x+3=101
minus 3 both sides
7x=98
divide both sides by 7
x=14
senior tickets cost $14
student tickets cost $3
that sounds unfair
It is the second function:
y=(1/2)^(x-3)
When x=0, the exponent is -3. (1/2)^-3 is 8.
y = 8+1 = 9
Answer:
answer is c
Step-by-step explanation:
i know cus i took the test
You would use PEMDAS so that means you would start by multiplying 3 with the parentheses 3(2+6d) on both sides then you would combine like terms so you would add 18d+18d. Then you would subtract 6- -5 on both sides then solve for a one-step equation
3(2+6d)-5=3(2+6d)-5
6+18d-5=6+18d-5
6+36d-5=6-5
1+36d=1
-1. -1
36d/36. 0/30
D=0
