Answer:

D, F

Step-by-step explanation:

The mnemonic SOH CAH TOA can help you with this. It reminds you ...

Sin = Opposite/Hypotenus

sin(40°) = x/b . . . . matches D

Cos = Adjacent/Hypotenuse

<em> cos(40°) = a/b . . . . no match</em>

Tan = Opposite/Adjacent

tan(40°) = x/a . . . . matches F

What is the equation of the line that has a slope of 0 and passes through the point (6,-8)

Fofino [41]

$\bf (\stackrel{x_1}{6}~,~\stackrel{y_1}{-8})~\hspace{10em} slope = 0 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-(-8)=0(x-6)\implies y+8=0\implies y=-8$

Solve for 3(2x-1)+7=6x-3-2(-4x)

Svetllana [295]

Answer:

x = 1.14

Step-by-step explanation:

3(2x - 1) + 7 = 6x - 3 - 2(-4x) [Given Equation]

6x - 3 + 7 = 6x - 3 + 8x [Distributive Property]

6x + 4 = 14x - 3 [Combine like-terms]

-8x + 4 = -3 [Subtraction Property of Equality]

-8x = -7 [Subtraction PoE]

x = 1.14 [Division PoE]
