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

Mrs. Rivera has more pencils
Answer:
x=20
Step-by-step explanation:
3x - 10 + 5x + 30 = 180
8x + 20 = 180
8x = 160
x = 160/8
x = 20
check:
3(20) - 10 + 5(20) + 30 = 180
60 - 10 + 100 + 30 = 180
50 + 100 + 30 = 180
150 + 30 = 180
180 = 180 ✓
Answer:
36 units
Step-by-step explanation:
to do this you must first find the lengths of all the sides with pythagorean theorem
for a to b you use
3^2 + 4^2 = c^2
9 + 16 = c^2
25 = c^2
c = 5
5 is one of the lengths
b to c uses the same equation
so
5 is another one of the lengths
for d to c your equation is
5^2 + 12^2 = c^2
25 + 144 = c^2
169 = c^2
13 is another of the lengths
d to a has the same length as c to d so there is another 13 unit length
so
5 + 5 + 13 + 13 is your equation to find the perimeter
5 + 5 + 13 + 13 = 36
that is your answer
