(5, 12) e (-10, -3)
x.......y...1
5.....12..1
-10..-3..1

12x -10y -15 + 120 -5y + 3x = 0
12x + 3x - 10y - 5y - 15 + 120 = 0
15x - 15y + 105 = 0 :(5)
3x - 5y + 21 = 0
m = -a/b
m = -3/-5
m(5) = 3/5

y-yo = m(x-xo)
y-14 = 3/5*(x-7)
y-14 = 3x/5 - 7/5
3x/5 - y + 14 - 7/5 = 0
3x/5 - 5y/5 + 70/5 - 7/5 = 0
3x - 5y + 70 - 7 =0
3x - 5y + 63 = 0
m(s) = -3/-5 = 3/5

m(r) = m(s) --> são paralelas

The variable c varies directly with a and inversely with b, and c = 3/20 when a = 2 and b =5.
RUDIKE [14]

Answer: k = 200/3

Step-by-step explanation:

If a variable, a varies directly with a variable, c, it means that as a increases, c increases and as a decreases, c decreases.

Also, If a variable, a varies inversely with a variable, b, it means that as a increases, b decreases and as a decreases, c increases.

The variable c varies directly with a and inversely with b. We would introduce a constant of variation, k. Therefore

a = kc/b

If c = 3/20 when a = 2 and b =5, then

2 = (k × 3/20)/5 = 3k/100

Cross multiplying, it becomes

3k = 100 × 2 = 200

k = 200/3

Marla will paint 48 pots . She plans to paint 9 pots each week . Draw an array to find how many weeks it will take Marla to pain
Leni [432]

Answer:

The number of weeks Marla will take to paint all the pots is  5 weeks and 3 days .

Step-by-step explanation:

Given as :

The number of pots Marla will paint = 48 pots

The number of pots she plans to paint each week = 9 pots

Let The number of weeks Marla needs to paints all pots = n weeks

<u />

<u>Now, According to question</u>

The number of weeks = \dfrac{number of pots Marla will paints}{\textrm The number of pots Marla will paints each week}

Or , n = \dfrac{48}{9}

∴ n = 5.3

So The number of weeks =  n = 5 weeks and 3 days

Hence The number of weeks Marla will take to paint all the pots is  5 weeks and 3 days . Answer
