Answer:
E. 500
Step-by-step explanation:
.3x=150
150/.3=500
Take the second equation and solve for y.
y - 3 = x
y = x + 3
Substitute this back into the first equation and solve for x.
x + 3 = x^2 + 3.
x = 0.
Plug this into either equation to get y.
This will be give a solution of...
x=0, y=3

Answer:
3 hours.
Step-by-step explanation:
Since they are heading away from each other, their relative velocity is 60+55 = 115 mph. 345 miles/115 mph = 3 hours.
Check by plugging in. In 3 hours, Max travels 3 * 60 mph = 180 miles from the starting point. Min travels 3 * 55 mph = 165 miles in the other direction from the starting point. The total distance is 165 + 180 = 345 miles.
Answer:
Step-by-step explanation:
Equation of a line giving 2 points is
y-y1=m(x-x1) where m is the slope and (x1,y1) is one of the points.
First we have to find the slope using formula
(y2-y1)/(x2-x1) where (x1,y1) and (x2,y2) are the points given
Slope m is (4-13)/(8--4) =-9/12 = -3/4
Looking at the answer choices, the only slope intercept equation that use the slope -3/4 is answer choice A
