Answer:
0.4
Step-by-step explanation:
x = -4/5 or -0.8
y = 1/3 or 0.333333
2(-0.8) + 6( 0.333333)
-1.6 + 2 = 0.4
To check the answer, sub in 67 for x and 25 for y in both equations...because for it to be a solution, it has to satisfy both of the equations.
(67,25)...x = 67 and y = 25
x + y = 92
67 + 25 = 92
92 = 92 (correct)
y = 3x - 4
25 = 3(67) - 4
25 = 201 - 4
25 = 197 (incorrect)
so (67,25) is NOT a solution to this system of equations because it does not satisfy both of the equations
Answer:
The quotient is : x+9
The remainder is : 13
Step-by-step explanation:
The question requires you to perform the long division method;
This will be;
![x-2\sqrt{x^2+7x-5}](https://tex.z-dn.net/?f=x-2%5Csqrt%7Bx%5E2%2B7x-5%7D)
start with the x term in x-2 and the first term in the function, x², to get x then multiply the x with x-2 to get x²-2x and perform the operation below;
x-2√x²+7x-5 -----------to first get x and then multiply x*[x-2]⇒x²-2x
- x²-2x+0 ------------perform subtraction of like terms
---------------------
9x-5 ----now divide this answer by x-2 ,starting with x and 9x
----------------------This will give , 9 then multiply 9 by x-2 to get 9x-18 and perform the subtraction operation as;
9x-5
- 9x-18
------------------------
13
So the answer will be; x+9 remainder 13
