Switch up the equation by subtracting.

       9-(8*n)=0

Solve  :    -8n+9 = 0  

Subtract  9  from both sides of the equation :  

                     -8n = -9  

Multiply both sides of the equation by (-1) :  8n = 9  

Divide both sides of the equation by 8:

                    n = 9/8 = 1.125

Subtract 9 from both sides

9=8n
-9 -9

So the 9 cancels itself out

Then do 8-9=-1

-1n

Then -1/-1 to cancel out the -1 and get the n alone

n=1 or leave it as -1/-1

She had 18 to start with because when you multiply 4 by 2 it’s 8, so then you add 8 to 10 which is 18.

Answer:

  (i) x° = 70°, y° = 20°

  (ii) ∠BAC ≈ 50.2°

  (iii) 120

  (iv) 300

Step-by-step explanation:

(i) Angle x° is congruent with the one marked 70°, as they are "alternate interior angles" with respect to the parallel north-south lines and transversal AB.

  x = 70

The angle marked y° is the supplement to the one marked 160°.

  y = 20

__

(ii) The triangle interior angle at B is x° +y° = 70° +20° = 90°, so triangle ABC is a right triangle. With respect to angle BAC, side BA is adjacent, and side BC is opposite. Then ...

  tan(∠BAC) = BC/BA = 120/100 = 1.2

  ∠BAC = arctan(1.2) ≈ 50.2°

__

(iii) The bearing of C from A is the sum of the bearing of B from A and angle BAC.

  bearing of C = 70° +50.2° = 120.2°

The three-digit bearing of C from A is 120.

__

(iv) The bearing of A from C is 180 added to the bearing of C from A:

  120 +180 = 300

The three-digit bearing of A from C is 300.

If dy/dx = x^2 + 4 what is the value of y
ad-work [718]

Answer:

  y = (1/3)x^3 +4x + c . . . . . for some constant c

Step-by-step explanation:

The anti-derivative of x^n is (x^(n+1))/(n+1). Applying this rule to each of the terms in dy/dx, we get ...

  y = (1/3)x^3 + 4x

There may be an added constant as well, conventionally represented by "c".

  y = (1/3)x^3 +4x +c
