Answer:
Slope is 3/2
Step-by-step explanation:
If you're going from point (1,4) to point (-3,-2), then your answer slope = -3/2.
If you're going from -3, -2 to 1,4 then it's 3/2 because you are going up 3, over 2 each time.

Answer:
b). 16.
Step-by-step explanation:
x^2 = 4
We can write this as
x^2 + 0x - 4 = 0
The discriminant (b^2 - 4ac) =
0^2 - 4 * 1* -4
= 16.
The <em><u>correct answer</u></em> is:
A) 300-70h = 30
Explanation:
The variable h represents the number of hours.
The distance between Mobile and Orlando is 300 km; the bus is traveling at 70 km/h, and for h hours, this gives us the expression 70h for the distance the bus travels.
300-70h gives us the difference between the total distance between the cities and the distance the bus has traveled. Since the bus is 30 km from Orlando, there will be 30 km left; this gives us 300-70h = 30.
