<span>Hello : let
A(5,-4) B(-1,8)
the slope is : (YB - YA)/(XB -XA)
(8+4)/(-1-5) =-2
an equation is : y=ax+b a is a slope</span>
y = -2x +b
the line through point A(5,-4) :
-4= -2(5)+b<span>
<span>b = 6
the equation is : y =-2x+6</span></span>
Answer:
40,000
Step-by-step explanation:
Given that:
Percentage Cost price of jewelry = 100%
Jewelery was sold at loss of 5% = (100%- 5%) = 95%
If sold at 5200 more ; profit made = 8%
That is ; (100% + 8%) = 108%
Difference between loss percentage and profit percentage = change in price sold
(108% - 95%) = 5200
13% = 5200
If ;
0.13 = 5200
The percentage cost price = 100% will be;
0.13 = 5200
1 = x
0.13x = 5200
x = 5200 / 0.13
x = 40,000
Answer:
We have the three angles of a triangle as an equation, so we can add them together, and they equal 180.
So:
4x+10+12x-6+3x+5= 19x+9=180
19x=171 ... so: x= 171/19 = 9.
So ABC = 102 .. Obtuse angle
BAC = 46 .. Acute angle
BCA = 32 .. Acute Angle
Edit:
Angle 1 = 180 - BAC = 180 - 46 = 134
Angle 2= 180 - ABC = 180 - 102 = 78
