In your point, y is 3 and x is 2. You have to fill in these values for x and y into each equation in A-D to see which one is "true". Let's start with A. y = -3x. Filling in 3 for y and 2 for x gives us 3 = -3(2). Does 3 equal -6? Of course not. So let's try B. y = x - 1. 3 = 2 - 1. Does 3 = 1? Of course not! Let's try C. y = 3x...3 = 3(2). 3 doesn't equal 6 either, so...last one. y = x + 1 is 3=2+1. Does 3 = 3? Yes! Finally! So the point on the coordinate plane is one the line represented by D.
Answer: x = -1/2y + 2
Step-by-step explanation:
12x + 6y = 24 To solve for x first start by subtracting 6y from both sides
- 6y -6y
12x = 24 - 6y Now divide each side by 12
x= 2 - 1/2y

Answer:
t = [0.493,4.2]
Step-by-step explanation:
The height of the rocket straight up into the air is given by :
We need to find the interval the rocket be at least 43 feet above the ground.
So, the required interval during which the rocket is at least 43 feet above the ground is [0.493,4.2].
