1) in order for two lines to be perpendicular, their gradients must multiply together to get -1

-1/3*b=-1

b=3

5=3(3)+b

5=9+b

b=-4

equation of the line is y=3x-4

2) parallel lines have the same gradient

4=2(-3)+b

4=-6+b

b=10

equation of the line is y=2x-10

Ugo [173]

Answer: 1 13/20 miles

Explanation:

$5 - 2\cfrac{1}{10} - 1 \cfrac{1}{4} = 5 \cfrac{0}{20} - 2\cfrac{2}{20} - 1 \cfrac{5}{20} = 4 \cfrac{20}{20} - 2\cfrac{2}{20} - 1 \cfrac{5}{20} = 1 \cfrac{13}{20}$

Determine whether the sequence is arithmetic or geometric.

Zarrin [17]

S1.
32, 16, 0, -16, ...
It's an arithmetic sequence:
$a_1=32;\ d=16-32=-16\\\\a_n=a_1+(n-1)d\\\\a_n=32+(n-1)\cdot(-16)=32-16n+16=48-16n$

S2.
32, 16, 8, 4, ...
It's a geometric sequence:
$a_1=32;\ r=16:32=\dfrac{1}{2}\\\\a_n=a_1r^{n-1}\\\\a_n=32\cdot\left(\dfrac{1}{2}\right)^{n-1}$

Answer: sequence 1 is arithmetic and sequence 2 is geometric.
