The picture is too blurry to read.
-7 because when it’s +(-) it’s always the same as the outside sign
-4 same thing explained above
-4
hope this helps
14-6y=44
-14 Both sides
-6y=30
÷-6 both sides
Y=-5
the answer is
-10 times- 5
Y = √8x³
dy/dt = 2√2 * 3/2 * √x * dx/dt
⇒ 5 = 2√2 * 3/2 * √2 * dx/dt
⇒ 5 = 6 dx/dt
⇒dx/dt = 5/6 cm/s
x coordinate is changing at 5/6 cm/s
Hope it helps!
