Let us say that:
x = the number of T shirts bought = 4
y = the number of leather jackets bought = 1
a = the price of the T shirts
b = the price of the leather jackets
With the given variables, we can say that the total cost
is:
total cost = a x + b y
Since, b = 6 a, therefore:
total cost = a x + 6 a y
total cost = a (x + 6 y)
Since total cost is 209, therefore we can calculate for a
since x and y are also given:
209 = a (4 + 6 * 1)
209 = a (10)
a = $20.9
<span>Therefore each T shirt cost $20.9</span>
Answer:
(5,0) and (0,3) have a slope of -3/5
Step-by-step explanation:
Here, we want to state a pair of points that have a slope of -3/5
Mathematically, we can have the slope of a straight line calculated as;
m = y2-y1/(x2-x1)
This could give points like (5,0) and (0,3)
Still need more information..like a picture
As a decimal 4/15 = 0.2666667
As a decimal 3/10 = 0.3 [talk about close]
3/10 is bigger.
You could take an average to find something between 4/15 and 3/10
1/2(4/15 + 2/10)
1/2(8/30 + 6/30)
1/2(14/30)
1/2(7/15)
7/30 is between the two given numbers..
Answer:
y + 1 = 8/9(x +4)
Step-by-step explanation:
Find the slope: [7- (-1)]/ [5 - (-4)] = 8/9
Using (-4, -1)
y-(-1) = 8/9[x- (-4)]
y + 1 = 8/9(x +4)
