Answer:

y=.5x-2

Step-by-step explanation:

If one line is perpendicular to another that means that their slopes are negative reciprocals

which means that the slope (or m in y=mx+b) is .5

so far we have

y=.5x+b

to solve for b we plug in (8,2)

2=.5(8)+b

2=4+b

-2=b

therefore our equation is

y=.5x-2

Solve for y.<br> -38 = 7v+17 – 12v

iren2701 [21]

Answer:

Step-by-step explanation:

$-38=7v+17-12v\qquad\text{subtract 17 from both sides}\\\\-38-17=7v+17-17-12v\qquad\text{combine like terms}\\\\-55=-5v\qquad\text{divide both sides by (-5)}\\\\\dfrac{-55}{-5}=\dfrac{-5v}{-5}\\\\11=v\to v=11$

The number of seats in each row of a theater forms an arithmetic sequence. The fifth row contains 22 seats. The tenth row contai

beks73 [17]

Let $s_n$ denote the number of seats in the $n$ -th row. $s_n$ is arithmetic, so

$s_n=s_{n-1}+d$

for some constant $d$ .

We're told $s_5=22$ and $s_{10}=37$ , so that

$s_{10}=s_9+d$

$s_{10}=(s_8+d)+d=s_8+2d$

$s_{10}=(s_7+d)+2d=s_7+3d$

and so on up to

$s_{10}=s_5+5d\implies37=22+5d\implies5d=15\implies d=3$

The pattern continues:

$s_5=s_4+3$

$s_5=(s_3+3)+3=s_3+2\cdot3$

and so on up to

$s_5=s_1+4\cdot3\implies22=s_1+12\implies\boxed{s_1=10}$
