Answer:

<h2>          x + 2y = - 6</h2>

Step-by-step explanation:

X-intercept:  (-6, 0)

Y-intercept:  (0, -3)    ⇒   b = -3

Slope:   m=\dfrac{y_2-y_1}{x_2-x_1}

m=\dfrac{0+3}{-6+0}=-\dfrac12

Slope-intercept form  y = mx + b

y=-\frac12x-3        {multiply both sides by 2}

2y = - x - 6          {add x to both sides}

x + 2y = - 6

Answer:

We'll need 2 points so we'll choose (-6, 0) and (0, -3).  

Let's calculate the slope (or 'm') using

Slope or m = (Y2 -Y1) ÷ (X2 -X1)

Slope ('m') = (-3 -0) / (0, - -6) = -3 / 6 = -1/2

Then we calculate the equation using:

(y - y1) = m • (x -x1)

(y - 0) = -1/2 * (x - -6)

y = -1/2 x -3

What does that equal
son4ous [18]

Answer:

3-\sqrt{10}

Step-by-step explanation:

We are given an expression and are asked to find what it equals. We can see that the two square roots are being multiplied, therefore they follow the same standard as any multiplication problem, do as followed :

\sqrt{5} *\sqrt{2}

\sqrt{10}

Since a square root and constant number are different terms, we cannot combine them together, therefore leave as is :

3-\sqrt{10}

Yaneev thinks of a number y. He subtracts three from the number, then doubles it. Then he subtracts three again, and doubles the
Sergio039 [100]

Answer: y=6

Step-by-step explanation:

The given number is y.

According to the question,

Step 1 . subtracts three from the number (y-3), then doubles it

i.e. Final number = 2(y-3)

Step 2 .  subtracts three again i.e. (2(y-3)-3), and doubles the number again

i.e. Final result  = 2(2(y-3)-3)

If the result is his original number y, then

2(2(y-3)-3) =y

⇒ 2(2y-6-3)=y   [ using distributive property]

⇒ 2(2y-9)=y

⇒ 2(2y)-2(9)=y [ using distributive property]

⇒ 4y -18=y

⇒ 4y -y= 18 

⇒ 3y= 18

⇒ y= 6    [Divide both sides by 3]

Hence,  y=6
