Answer:
this is not enough information
Slope: (y2-y1)/(x2-x1)
(-13-(-7)) = -6
-6/3 = -2
x - 3 = 3, x = 6
The solution: x = 6
The answer is 21.5 or in a fraction its 43/2
Answer:
51 and 42
Step-by-step explanation:
Use
x + y = 93
x - y = 9
Add those two equations together and you get 2x = 102
*y is not in the equation anymore because y + -y = 0*
Divide both sides by 2
x = 51
plug x into one of the equations; let's use x + y = 93
Then you get, 51 + y = 93
Subtract both sides by 51 and you get y = 42
Plug both in the other equation to make sure the numbers work.
51 + 42 = 93; true
51 - 42 = 9; true
Answer is $330.63 because 15% of 287.5 is 43.125 then you add 47.125 to 287.5 and get 330.63
