Let y=total monthly income
Let x=each time app is opened
y=25+(.003x)
The answer is 8x.
You are combining like terms as 5 and 3 both have x so you are simply adding 5+3= 8
Answer:41550
Step-by-step explanation:
30000×.07=2100
2100×5.5=11550
11550+30000=41550

Ok so, based on the graph lets say that x = seconds and y = depth of dolphin. the interception in both points is when they are at 0 i.e when x is equals 0 and y equals 0. So At 0 seconds, the dolphin is 42 feet below the surface. So we say that x = 0, y = -42 and then the y intercepts = -42 so the point of interception is(0 (seconds),-42(depth of the dolphin)) When the clock says it's 14 seconds, the dolphin is even with the surface (0 below the surface this time). So we say that x = 14, y = 0. In this case The x intercept = 14 (14,0). But we need to calculate The slope with the formula= (y2 - y1)/(x2 - x1) = 42/14 = 3. Therefore, the formula for this line is y = 3x - 42.
