The solutions you get when you solve the formula are the corresponding y coordinates to your x value. So say a point on your graph is (2,3). The first number is x and the second is y. (x,y). The number you plug into your function is x,or in this case: 2. The solution to the equation when the x value is plugged in is y, or 3. Therefore, giving you a point on your graph.
Since C is 2mi east of A and 2mi south of B, the shortest distance from A to B would be a straight line which is equal to the hypotenuse of a right triangle with a base of 2mi and a height of 2mi..
d^2=x^2+y^2
d^2=2^2+2^2
d^2=4+4
d^2=2*4
d=√(2*4)
d=2√2 mi (exact)
d≈2.83 mi (to nearest hundredth of a mile)
Answer:
70% = 7/10
Step-by-step explanation:
The fraction is given in the problem statement as 70%. It can be expressed as 7/10, 0.7, 0.70, and many other ways. Take your pick.
Other number: x
one number: 5x - 2
x (5x - 2)=72
5x^2 - 2x = 72
Answer:
13x^2+2x+5
