Answer: a=-1

Step-by-step explanation:

-11-5a=6(5a+4)

-11-5a=30a+24

-11-5a-30a=24  

-5a-30a=24+11

-35a=35            

a=-1

-11-5a=6(5a+4) .... Distribute the 6 to 5a and 4
-11-5a=30a+24 .... Subtract 30a from both sides
-11-5a-30a=24  .... Add 11 from both sides
-5a-30a=24+11 .... Add like terms
-35a=35            .... Divide -35a from both sides
a=-1                  .... Final answer

Find the slope of the line passing through the points of (3,-5) and (-9,-6)
slavikrds [6]

Answer:

1

m = ---

12

Step-by-step explanation:

The formula is y2-y1

---------

x2-x1

(x1,y1) (x2,y2)

(3,-5) (-9,-6)

You get the 2 Y's and subtract them

Do the same with the X's

Y's above , X's below

(y2- y1)

⬇

-6-(-5) -1 1

--------- = ---- = ---- = m

-9-(3) -12 12

⬆

(×2- x1)

This equation is backwards, thats why it was harder to understand. (-9,-6) is farther left and below point (3,-5), making it the REAL first point in the equation.

Sebastian solved the radical equation y + 1 = but did not check his solution. (y + 1)2 = y2 + 2y + 1 = –2y – 3 y2 + 4y + 4 = 0 (
Softa [21]

Answer:

There are no true solutions to the equation.

Step-by-step explanation:

<u><em>The correct equation is</em></u>

y+1=\sqrt{-2y-3}

Solve for y

squared both sides

(y+1)^2=(-2y-3)

(y^2+2y+1)=(-2y-3)

y^2+2y+1+2y+3=0

y^2+4y+4=0

(y+2)(y+2)=0

y=-2

<em>Verify</em>

substitute the value of y in the original expression

-2+1=\sqrt{-2(-2)-3}

-1=1 ----> is not true

therefore

There are no true solutions to the equation.

QR =12 because you set up a proportion 21/14=x/8 then cross multiply and get 14x=168 then you divide and get 12
