Answer:

  -25

Step-by-step explanation:

Solving for v, we find ...

  -3v -5 = 4

  -3v = 9 . . . . . add 5

  v = 9/-3 = -3 . . . . divide by -3

Substituting for v in the expression of interest, we have ...

  5v -10 = 5(-3) -10 = -15 -10

  5v -10 = -25

:( <br> A=?<br> B=?<br> please help me
Helen [10]

a= 16x+16

b= 40x + 15

Step-by-step explanation:

We know that perimeter of a rectangle is

2(l + b)

So therefore

2(8x + 3 + 5) = a

=  > 16x+ 6 + 10 = a

=  > 16x + 16 = a

Answer= A) that is perimeter is 16x+16

We know that area of a rectangle is l×b

So therefore

(8x + 3) \times 5

= 40x + 15

Answer = b) that is area is 40x + 15

For the graph x = 12 find the slope of a line that is perpendicular to it and the slope of a line parallel to it. Explain your a
blagie [28]
Check the picture below.

that's the line of x = 12, just a straight vertical line, notice the green line, that's parallel to it, and the red line, that's perpendicular to it.

let's pick two points for each to get their slopes, hmm say for the green one (5,2) and (5,4)

\bf (\stackrel{x_1}{5}~,~\stackrel{y_1}{2})\qquad &#10;(\stackrel{x_2}{5}~,~\stackrel{y_2}{4})&#10;\\\\\\&#10;% slope  = m&#10;slope =  m\implies &#10;\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{4-2}{5-5}\implies \stackrel{und efined}{\cfrac{2}{0}}

and for the red one hmmm (3,2) and (7,2)

\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{2})\qquad &#10;(\stackrel{x_2}{7}~,~\stackrel{y_2}{2})&#10;\\\\\\&#10;% slope  = m&#10;slope =  m\implies &#10;\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{2-2}{7-3}\implies \cfrac{0}{4}\implies 0
