Given that cos (x) = 1/3, find sin (90 - x)

drek231 [11]

$\sin{(A - B)} \equiv \sin{A}\cos{B} - \cos{A}\sin{B} \\\\
\therefore \sin{(90 - x)}\\
 = \sin{(90)}\cos{(x)} - \cos{(90)}\sin{(x)} \\
= (1)\cos{(x)} - (0)\sin{(x)} \\
= \cos{x} - 0 \\
= \cos{x} \\
= \frac{1}{3}

Identify the properties used for the first two steps in simplifying 6ab2 + 4a2b – 3ab2 + 3a2b – 2a2b2.

Kryger [21]

The expression $6ab^2+4a^2b-3ab^2+3a^2b-2a^2b^2$ has two similar pairs of conjunctions.

1. Rewrite this expression as
$6ab^2+4a^2b-3ab^2+3a^2b-2a^2b^2=$
$=(6ab^2-3ab^2)+(4a^2b+3a^2b)-2a^2b^2$
and then
2. add the similar conjunctions

 $(6ab^2-3ab^2)+(4a^2b+3a^2b)-2a^2b^2=3ab^2+7a^2b-2a^2b^2$ .

Three students are working to find the solution set of this system of equations: y = 3x + 10 2y = 6x – 4

ivanzaharov [21]

Answer:

Step-by-step explanation:

Since this is a system with two equations, we can easily use a graphing calculator to find the solution

The intersection between the graphs of the equations

y = 3x + 10

2y = 6x – 4 (if we divide by two)

y = 3x - 2
