Answer:
18
Step-by-step explanation:
9 + 18 = 27
9 x 2 = 18
Answer:
Josh has 29 coins.
Step-by-step explanation:
Let Terry have x coins then Josh has x + 12 coins.
Together they have x + x + 12 coins so we can form the equation:
x + x + 12 = 46
2x + 12 = 46
2x = 46 - 12 = 34
x = 17, so Terry has 17 coins and Josh has 17 + 12 = 29 coins.

Answer:
y = 5x -2
Step-by-step explanation:
The slope is given by the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (8 -3)/(2 -1) = 5
The y-intercept is given by the formula:
b = y -mx
b = 3 -5(1) = -2
Then the slope-intercept form equation is ...
y = mx +b
y = 5x -2 . . . . . . . . using the m and b we found above
Answer:
B
Step-by-step explanation:
The y-axis shows the number of gallons of water left (with respect to time).
The x-axis shows the time.
Domain is the set of x-values that is allowed. Looking at the graph, we see that the water drains within 0 to 12 minutes. After 12 minutes there is no water left, so that's not feasible. Hence, the domain would be from 0 to 12.
Looking at the choices, that is B, 0 ≤ x ≤ 12
