Square both sides to find 2s +8 = s^2 and then subtract so it would be s^2 -2s -8 = 0. Then you factor to get (s-4)(s+2)=0 and get s={-2,4} then you check for answers that are extraneous and find that -2 is an extraneous answer which means s=4

Square both sides:

2s + 8 = s²

0 = s² - 2s - 8

Now factor:

0 = (s-4)(s+2)

s - 4 = 0 OR s + 2 = 0

s = 4 OR s = -2

Since square root cannot be negative, s = -2 is not possible,
so we are left with s = 4

Line bc is represented by 3x + 2y =8 line ad is a represented by -3 x -2y =6 what is the relationship of line bc to line ad expl
Vlad1618 [11]

Answer:

Parallel lines

Step-by-step explanation:

Line BC:

3x + 2y =8

Line AD:

-3x - 2y =6

Adding both equations, in this case, gives us the point at which the lines intersect:

3x + 2y-3x-2y =8+6\\0=14

Since zero will never equal fourteen, the equation above means that lines BC and AD will never intersect. When two lines have no point in common, they are said to be parallel lines.

Pls help. No files pls. Will give brainliest.

To find f(-20), first figure out which piece x = -20 fits with.

Since -20 < -12, x = -20 first in the domain used by the third piece.

For f(-20), treat this function as if it was just f(x) = 3x-7.

f(-20) = 3(-20) -7

         = -60 - 7

         = -67

Answer:

<h3>b=\frac{t-5}{4}</h3>

Step-by-step explanation:

4b+5=t

First, you must get the variable alone! Substract 5 from both sides!

4b<u>+5=t </u>

    -5  -5

The 5 cancels out because 5-5=0

The new equation is 4b=t-5

You must divide by 4 to get the variable alone since your solving for b!

<u>4b=t-5</u>

4      4

b= \frac{t-5}{4} \\

This is your answer!

Can someone plz help me i will thank u so much

Answer:

2 hours and 29 minutes

Step-by-step explanation:

if you change 9 hours to minutes you get 540 plus 17 equals 557. if you turn 6 hours to minutes it's 360 plus 48 equals 408. 557 minus 408 equals 149 minutes. Now if you convert it to hours and minutes you need to divide by 60. So if you divide it you get 2 hours and 29 minutes. hope this helped! :)
