Answer:
YES PLEASE!!! Can you solve this problem?
Explanation:
June is driving from brookline, massachusetts to brooklyn, new york. The cities are 200 miles apart. Pretend june lives in a world in which she encounters no traffic jams and can drive at a constant speed of 50mph the entire way. Consider the following function. the distance june has traveled, c, is a function of her driving time, t.
write a formula that describes this function
D. Prefix “pseudo” means “false” or “unreal”
Answer:
4/3
Explanation:
For xy-plane coordinates, points are written as (x, y).
This question gives us two points and two line equations to solve this. Let's start with the first one.
Since p is the x value of the point and r is the y value of the point, we can place these values in our equation y = x + b as follows:
r = p + b
Now we do the same with our second point and line equation. We will substitute 2p for x and 5r for y in the equation y = 2x + b. So we get this:
5r = 2(2p) + b
5r = 4p + b
Since we have this two equations with the same two variables, now we can solve them using the elimination method.
In this case I eliminated b as it is constant in both equations. To do this I subtract the equations in order to cancel the b variable.
5r = 4p + b
r = p + b
_______ -
5r - r = 4p + b - p - b
4r = 3p
4/3 = p/r
The answer is B because the rest can not be adaptions!
