What is the solution of the system defined by y = -x + 5 and 5x + 2y = 14? a. `x= (1)/(3)`, `y= (11)/(7)` b. `x= (4)/(3)`, `y= (11)/(3)` c. `x= (5)/(11)`, `y= 0` d. `x= (4)/(3)`, `y= 1`

Ineed i been stuck on this question since yesterday

Select the correct answer from each drop-down menu. consider the following polynomials equations. 3x^2(x-1) and -3x^3+ 4x^2-2x+1 perform each operation and determine if the result is a polynomial. is the result of a + b a polynomial? yes or no is the result of a - b a polynomial? yes or no is the result of a · b a polynomial? yes or no

Will give brainliest for correct answer 8. use the distance time graph to answer these questions: a. what does the graph tell us about the velocity of the car? b. what is the average velocity of the car? (show work) c. is the velocity reflected in the graph positive or negative?d. is there any point on the graph where the car is not moving? how do we know?
