Answer: -1 so -1x
Step-by-step explanation:
You use the y1-y2/x1-x2 formula. so 9-7 is 2 and 5-7 is -2 you you have 2/-2 that simplifes to be -1
60 degree angle.
Hope this helps
Step-by-step explanation:
x= -2,
(x - 5) / 2= -6
( (-2) - 5) / 2= -6
(-7) / 2 = -6
-3.5 = - 6
right hand side not equal to left hand side of this equation.so,x= -2 cannot exist for this equation.
x=2,
(x - 5) / 2= -6
(2 - 5) / 2= -6
(-3) / 2= -6
-1.5 = - 6
right hand side not equal to left hand side of this equation.so,x= 2 cannot exist for this equation.
x= -17
(x - 5) / 2= -6
( ( -17) - 5) / 2= -6
(- 22) / 2= -6
-11 = -6
right hand side not equal to left hand side of this equation.so,x= -17 cannot exist for this equation.
x= -7,
(x - 5) / 2= -6
( ( -7) -5) / 2= -6
(-12) / 2= -6
-6= -6
right hand side equal to left hand side of this equation.so,x= -7 exist for this equation.
firstly chain rule is dy/dx = dy/du * du/dx
a) y = 5u² + u - 1 hence dy/du = 10u +1
u = 3x +1 hence du/dx = 3
so dy/dx = 3(10u +1) {sub in u and expand}
b) y= u^-2 hence dy/du = -2u^-3
u=2x+3 hence du/dx = 2
so dy/dx= 2(-2u^-3) {sub in u}
The square root of 96 is the same thing as the square root of (16 x 6),
and that in turn is (√16) times (√6) .
We know the square root of 16 right away, so we can write
√96 = 4 √6 .
You have asked what goes into that 3 times. "Goes into..." is just
another way of stating division.
What goes into 4√6 three times is <em>(4/3) √6 </em>.
That number is about 3.266 (rounded) .
