If dy/dx = x2 + 4, what is the value of y? a. x3/2 +4x + c b. x3/2 +2x2 + c c. 2x + c d. x3/2 + 4x + c

1) Given dy / dx = x^2 + 4 = y is the function whose derivative is x^2 + 4.

2) y = x^3 / 3 + 4x + constant

Prove d y / dx = 3x^2 / 3 + 4 + 0 = x^2 + 4

x^3 / 3 + 4x + C

B. because the 7 represents "seven times", x represents "a number", 12 represents "plus twelve", and -4 represents "minus four"

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
