Y=mx+c
1) FIND M
Perpendicular lines formula
m1 x m2 = -1
- gradient of the lines multiplied together equals to -1
Substitute
m1 x m2 = -1
12 x m2 = -1
m2 = -1/12
m2 = -0.083
2) FIND C
Now we know m, y and x, so we can find c.
(x,y) -> (10,-5)
y=mx+c
-5=-0.083*10+c
-5=0.83+c
-5-0.83=c
c=-5.83
So the equation would be
y=-0.08x+5.83
Inverse is used to find the value of an angle. The inverse of a trigonometric function gives you the angle instead of the ratio. Commonly, these are denoted with the prefix "arc-". So, the inverse of the tan function is the arctan function.
The reciprocal of a trigonometric function is simply its algebraic reciprocal--that is, 1 over the function.
The Nswer is c because im tired and bored

Left to right: Zoe, Johana, Kami, Craig
Step-by-step explanation:
The values of x can be found by solving each of the equations.
A) x/-12 -2 = -22 ⇒ x = -12(-22 +2) = 240 . . . (first step: add 2)
B) 3x -21 = 15 ⇒ x = (15 +21)/3 = 12
C) -12x +2 = -22 ⇒ x = (-22 -2)/-12 = 2 . . . (first step: subtract 2)
D) 1/2x +66 = 126 ⇒ x = 2(126 -66) = 120

Zoe's equation requires adding 2 as the first step. It is equation A.
Craig's equation's solution is half that of Zoe's. 240/2 = 120. Craig's is equation D.
Kami's equation requires subtracting 2 as the first step. It is equation C.
Johana's equation's solution is 6 times that of Kami's. 6·2 = 12. Johana's is equation B.

Answer:
1 / q^3 = 1 / q^n
n = - 3
Step-by-step explanation:
1/r^-4 = r^4
p^3 * q^2 * p^4 * q^n * r^3 * r^4 = p^7 q ^5 r^7
(p^3 * p^4 *q^2 * r^3 * r^4 ) / ( p^7 * q^5 * r^7) = 1/q^n
(p^7 * q^2 * r^7) / (p^7 * q^5 * r^7) = 1/q^n
q^2 / q^5 = 1/q^n
1 / q^3 = 1 / q^n
