Answer: x=−1

Explanation:

Step 1. You need to simplify both sides of the equation.

8x=−4(x+3)

8x=(−4)(x)+(−4)(3)   (Remember to distribute)

8x=−4x+−12

8x=−4x−12

Step 2. Then add 4x to both sides.

8x+4x=−4x−12+4x

12x=−12

Step 3. Lastly, divide both sides of the equation by 12.

12x/12 = -12/12

x=−1

Final Answer: x=−1

Hope I could help! :)

Answer:

x = -1

Step-by-step explanation:

8x = - 4(x + 3)

8x = -4x - 12

+4x  +4x

<u>12x = -12</u>

12       12

x = -1

  • Remember, a negative times a positive equals a negative
  • Remember, a negative divided by a positive equals a negative

Hope this helps you!!! :)

Which function represents the number of seconds, s, in d days? (Hint: The number seconds in a day is 24 × 60 × 60 = 86,400.)
vaieri [72.5K]
<em>f(d)=86,400·d</em>
if you set 1 day (d=1) you get f(1)=86,400 sec
if you set 1 day (d=2) you get f(2)=172,800 sec
...etc.

what is the y-intercept of the equation of the line that is perpendicular to the line y=3/5x+10 and passes through the point (15
ohaa [14]

The slope of the given line is the coefficient of x, 3/5. The slope of the perpendicular line will be the negative reciprocal of that: -1/(3/5) = -5/3.

The point-slope form of the equation for a line of slope m through point (h, k) can be written ...

... y = m(x -h) +k

For your point and the slope found above, this becomes

... y = (-5/3)(x -15) -5

When x=0, this is

... y = (-5/3)(-15) -5 = 20

The y-intercept is 20.

Which equation, when solved, results in a different value of x than the other three?
kicyunya [14]
I would have to say -7(1/8)x-4/3=20.


The first and the second one both result in
-23 5/7

The last one results in -24 8/21

but the third one is -22 3/8.

So your answer is either the third of the last one. I assumed the third because, it is lower than all others and the first two are closer to 24 than they are to 22. It’s your choice on how to judge it.
