Sholpan [36]

Answer:

12 times 5=60 not 70

Step-by-step explanation:

60+24y=-5y-5

29y+60=-5

29y=-65

y=-65/29 or y= about -2.38

Addition Property of Equality
Subtraction Property of Equality

Algebra I

Factoring

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle 10 = ax + bx$

Step 2: Solve for x

Factor: $\displaystyle 10 = ax + bx \rightarrow 10 = x(a + b)$
[Division Property of Equality] Divide a + b on both sides: $\displaystyle 10 = ax + bx \rightarrow x = \frac{10}{a + b}$

What’s the value of tan (3arc cos 3/4)

Volgvan

<h2>Answer: -1.469</h2>

This trigonometric function can be written as:

$tan (3 cos^{-1} (\frac{3}{4}))$ (1)

Firstly, we have to solve the inner parenthesis:

$cos^{-1} (\frac{3}{4})= 41.409$ (2)

Substituting (2) in (1):

$tan (3(41.409))=tan(124.228)$ (4)

Finally we obtain the value:

$tan(124.228)=-1.469$
