Suppose that the functions and are defined for all real numbers as follows. r(x)=3x^(2) s(x)=2x write the expressions for (r-s)(
nirvana33 [79]
The expression for (r-s)(x) is found by subtracting s from r.  That difference is 3 x^{2} -2x.  The expression for (r+s)(x) is found by adding them, which is 3 x^{2} +2x.  Now we are told to evaluate (r*s)(x) which means they want us to multiply those and state the "new" expression that results.  (3 x^{2} )(2x)=6x^3.  There you go!

Answer:

  one solution is (0, -2)

Step-by-step explanation:

The line y = -x is the boundary of the solution space of the first inequality. The less-than symbol (<) tells you that the line will be dashed and the shading will be below it. The line has a slope of -1 and goes through the y-intercept point (0, 0).

The line y = x - 2 is the boundary of the solution space for the second inequality. The less-than-or-equal-to symbol (≤) tells you the line will be solid (or equal to) and the shading will be below it (less than). The line has a slope of +1 and goes through the y-intercept point (0, -2).

The area of the graph where the shadings overlap is the solution space for the system of inequalities. Any point in that area will do, including points on the solid line where y < -x. (0, -2) is one such point.

What is the solution to the system x+ y =4 and 2x - y = -1
Lostsunrise [7]

Answer:

Step-by-step explanation:

hello :

the system is :  x+ y =4 ...(*)

                       2x - y = -1...(**)

add(*) and (**) : 3x=3    so : x=1

put this value into (*) : 1+y=4     so : y=3

one solution : (1 , 3)
