Answer:
-9x +6
Step-by-step explanation:
The usual statement of the distributive property tells you how this works:
a(b + c) = ab + ac
-1(9x -6) = (-1)(9x) +(-1)(-6) = -9x +6
As always, distance = rate times time. Here, distance is unknown, but we have the speed 88 mph and the time 0.25 hour. Thus,
distance traveled during chase = (88 mph)(0.25 hr) = 22 miles.
You need to solve this "system of linear equations." In other words, find a point (x,y) that satisfies both 4x-3y=17 and 2x-5y=-11.
Try solution by elimination. Multiply the 2nd equation by -2 to obtain -4x+5y=22. Add this result to the 1st equation. I'd suggest you write this out to see what is happening.
4x-3y=17
-4x+10y=22
----------------
7y=39. Solving for y, we get y=39/7 (a rather awkward fraction).
Now find x. To do this, substitute 39/7 for y in either of the given equations. Solve the resulting equation for x.
Write your solution in the form (x, y): ( ? , 39/7).
3 > 14
? > 10
Cross Multiply
? = 30/14
