Answer:
A) 12
You know:
<em>AB= 3x</em>
<em>AB= 3xAC= 17</em>
<em>AB= 3xAC= 17BC= 2x-3</em>
Therefore, you can put the values in a number line for reference. By doing this you can see that <em>3x + 2x -3</em> (or AB +BC) <em>= 17</em> (or AC)
From here you can set up the equation to be:
<em>1</em><em>7</em><em> </em><em>=</em><em> </em><em>2</em><em>x</em><em> </em><em>-</em><em> </em><em>3</em><em> </em><em>+</em><em> </em><em>3</em><em>x</em>
and solve for x by combining like terms:
<em>1</em><em>7</em><em>=</em><em> </em><em>5</em><em>x</em><em>-</em><em>3</em>
adding 3 to both sides:
<em>2</em><em>0</em><em>=</em><em>5</em><em>x</em>
dividing each side by 5:
<em>20/5=5x/5</em>
to get:
<em>x=4</em>
then, you're gonna plug in your <em>x</em> (4) into <em>3x</em> (your AB) in order to solve for AB:
<em>AB=3x</em>
<em>AB=3x =3(4)</em>
<em>AB=3x =3(4) =12</em>
therefore, your answer is:
AB = 12
Answer:
<em>The graph of </em>y + 1 = −3/5 (x − 4)<em> would be a straight line. The graph figure is attached below.</em>
Step-by-step explanation:
As the linear equation y + 1 = −3/5 (x − 4) is given.
Since y-y₁ = m (x - x₁) is the Point-slope form is the general form y-y₁=m(x-x₁) for linear equations.
Hence, from the linear equation we can determine the slop which is m = -3/5
Also, when we put x = 0 in the linear equation, we determine the y-intercept as follows:
y + 1 = −3/5 (x − 4)
y + 1 = -3/5(-4) ∵x = 0
y = 12/5 - 1
y = 7/5
y-intercept: 7/5
Hence,
Table for some points can be made for x and values as:
<h3><em>x y</em></h3>
0<em> </em><em> 7/5</em>
<em>1 4/5</em>

Answer:
The answer is 30 centimeters per month or 30/1
Step-by-step explanation:
Its actually pretty simple I convert it into a linear function which looks like this representing the answer
y=30x
the x represents the # of months
