Option A is the right answer.

We know that the y-intercept is (0, 3), since that's the point on y-axis. Now that we know this, we know the value of 'b'

y = mx + b
y = mx + 3

Now all we have to do is solve for m. Recall that 'm' represents the slope, and that the equation to find the slope is rise/run. Essentially, you have to find two points and figure out the number of units you have to travel through the x-axis and y-axis.

In this question, they've already gave us two points (The black dots) that we can use to find the slope. In order to get the dot on the to the dot on the bottom, we have to go down 5 times. This means that the rise is -5.

Now all we have to do is go right until we reach the point. In this question, you have to go the right 4 times, making the run 4.

And so we've found the slope: -5/4.
Since the slope is 'm,' we can now complete our equation.
y = mx + 3
y = -5/4x + 3

Let me know if you need me to explain anything in more depth :))

I need help.. 
Debora [2.8K]
This is exactly like the one with the 'n's that you posted yesterday.
I guess you didn't get enough help on that one to understand it.

<span><u>7k/8 - 3/4 - 5k/16 = 3/8</u>

3/4 is the same as 6/8.
Add it to each side of the equation:

7k/8         - 5k/16 = 9/8

Multiply each side by 16 :

14k - 5k = 18

Add up the 'k's on the left side:

9k = 18

From this point, you can proceed directly to the numerical value of 'k'
if you need it.<u />

In your question, you said you need help, and I showed you how to
strip the problem down so that the only thing left is ' k = something '.
Giving you the answer is no help.  Nobody actually needs the answer.

Ipatiy [6.2K]

Answer:

2(3x - 7) =  - 4(x + 5) + 3 \\ 6x - 14 =  - 4x - 20 + 3 \\ 6x + 4x =  - 20 + 3 + 14 \\ 10x =  - 3 \\  \\ x =  \frac{ - 3}{10}  \\  \\ x =  - 0.3

I hope I helped you^_^

A bulletin board has a perimeter of 200 inches. Which expression expresses the area A(w) of the bulletin board as a function of
mr Goodwill [35]

Answer:

area A(w) of the bulletin board as a function of its width, w =[100-w]*w= 100w-w^{2}

Step-by-step explanation:

  • let, the shape of the bulletin board is a rectangle,
  • then the perimeter of it = sum of all sides

= 2[length+width] = 2[l+w]

(let l: length, w : width )

  • so, 200 = 2[l+w]

100= l+w ( dividing both the sides by 2)

so, l= 100-w

  • area = length*width=l*w=[100-w]*w
  • therefore,area A(w) of the bulletin board as a function of its width, w =[100-w]*w= 100w-w^{2}
