The y-intercept of the equation that represent the relationship between x and y in the table is -6

<h3>How to determine the y-intercept?</h3>

From the table, we have the following highlight:

As the x values increase by 2,
The y values increase by 3

This means that:

As the x values decrease by 2,
The y values decrease by 3

From the table, we have:

x = 2 when y = -9

Decrease the values of x and y

x = 0 when y = -6

Hence, the y-intercept is -6

Simplify 6(x+y)+(x-y)

MakcuM [25]

When you have something multiplied by more than one term in parentheses, you multiply that something (in this case 6) by both terms (x and y).
6x+6y+x+y. Add like-terms. 7x+7y

How do I solve <br><img src="https://tex.z-dn.net/?f=%20%20%5Csin%28%20a%20%29%20%20%3D%20.8325" id="TexFormula1" title=" \sin(

Serga [27]

Answer:

$a=56.4\degree$

Step-by-step explanation:

Let $a$ be an acute angle.

To solve: $\sin(a)=0.8325$ , we take the sine inverse of both sides to obtain:

$\sin^{-1}(\sin(a))=\sin^{-1}(0.8325)$

Recall composition property of a function and its inverse function.

$f^{-1}(f(x))=x$

We apply this property to the left hand side to obtain;

$a=\sin^{-1}(0.8325)$

We now use our scientific calculator to obtain;

$a=56.3564115\degree$

We round to the nearest tenth to obtain;

$a=56.4\degree$
