The slope of a line going through points (5,7) and (3,1) is 6/2 so 3/1 = slope of 3
Answer:
Hope this helps!
Step-by-step explanation:
Slope = 5/-2
Slope (m) =
ΔY
ΔX
=
5
-2
= -2.5
θ =
arctan( ΔY ) + 180°
ΔX
= 111.80140948635°
ΔX = -1 – 3 = -4
ΔY = 5 – -5 = 10
Distance (d) = √ΔX2 + ΔY2 = √116 = 10.770329614269
Equation of the line:
y = -2.5x + 2.5
or
y =
- 5 x
2
+ 5
2
When x=0, y = 2.5
When y=0, x = 1
Profit made by jeweler from buying and reselling ounces of gold is 140.89 per ounce
<u>Solution:</u>
Given that
Price at which jeweler buy gold = 1235.55 per ounce
Price at which jeweler resells gold = 1376.44 per ounce
We need to calculate profit.
Buying price of 1 ounce of gold = 1235.55
Reselling price of 1 ounce of gold = 1376.44
<em>Profit = Reselling price – buying price</em>
So profit on 1 ounce of gold = 1376.44 – 1235.55 = 140.89
Hence profit made by Buying and Selling gold will be 140.89 per ounce
Answer:
It should either be 69 or 70
Step-by-step explanation:
Answer=65 pairs of shoes
Given the data, the following equation can be made where x is equal to the number of shoes sent to the outlet mall.
845=4x+4x+4x+x
845=13x
divide both sides by 13
65=x
65 pairs of shoes were sent to the outlet mall
