Answer:
y = x /2 - 1/2
Step-by-step explanation:
y = h(x)
y = 2x + 1 Interchange x and y
x = 2y + 1 Subtract 1
x - 1 = 2y Divide by 2
x/2 - 1/2 = y
y = x/2 - 1/2

Answer:
1/2 or 0.5
Step-by-step explanation:
Because there is only 6 sides, the probability of it landing on a number greater than 3 is 1/2. On a 6 sided die 4,5 and 6 are all greater than 3. 1,2, and 3 are all less than 3. So 1/2 is the probability.
Answer:
x = 5/3
Step-by-step explanation:
Solve for x:
7 x - 15 = -2 x
Add 2 x to both sides:
7 x + 2 x - 15 = 2 x - 2 x
2 x - 2 x = 0:
7 x + 2 x - 15 = 0
7 x + 2 x = 9 x:
9 x - 15 = 0
Add 15 to both sides:
9 x + (15 - 15) = 15
15 - 15 = 0:
9 x = 15
Divide both sides of 9 x = 15 by 9:
(9 x)/9 = 15/9
9/9 = 1:
x = 15/9
The gcd of 15 and 9 is 3, so 15/9 = (3×5)/(3×3) = 3/3×5/3 = 5/3:
Answer: x = 5/3
Answer:

Expression equivalent to - 8
Answer: 216 in
Step-by-step explanation: I used the formula A=1/2(b1+b1)h and I filled it in by doing A=1/2(6+12)6 and then I divided the height by 1/2 and i multiplied 72 by 3 which is 216 in.
