(The answer to the equation is 32.8)
Answer:
y = -x - 2
Step-by-step explanation:
Find two points on the line
(0, -2)
(4, -6)
(Y2-Y1)/(X2-X1) = gradient of the line
Where (X1,Y1) = (0, -2) and (X2,Y2) = (4, -6)
(-6--2)/(4-0)
(-6+2)/4
(-4)/(4)
-1
Y = (-1)X + c
Substitute either set of coordinates in to find c.
(0, -2)
Y = (-1)X + c
-2 = (-1)0 + c
-2 = 0 + c
-2 = c
(4,-6)
Y = (-1)X + c
-6 = (-1)4 + c
-6 = -4 +c
-6 + 4 = c
-2 = c
Y = -X -2
Answer:
$16.90
Step-by-step explanation:
First you need to find how much the markup is in dollars.
Multiply 13(0.3).
This will give you 3.9.
Then you add this to the original cost of the glasses.
13+3.9= 16.9.
So, the final cost of the glasses is $16.90.
Let 6x represent the men
5x represents the women
The ratio of men to women is 6 to 5 or 6/5
6x / 5x = 1500/ W where W is the number of women
6/5 = 1500/W
W = 1250 women
