Answer:
Step-by-step explanation:
Hello : let A(2,3) B(4,6)
the slope is : (YB - YA)/(XB -XA)
(6-3)/(4-2) = 3/2
an equation is : y=ax+b a is a slope
y = (3/2)x +b
the line through point (2,3) : 3 = (3/2)(2)+b
b = 0
the equation is : y =(3/2)x
Answer:
20kg of $0.89 candy
10kg of $1.10 candy
Step-by-step explanation:
Candy 1 = 0.89 per kg
Candy 2 = 1.10 per kg
Total kilogram, kg = 30
Let candy 1 = x ; candy 2 = (30 - x) ;
0.89x + 1.10(30 - x) = 0.96(30)
0.89x + 33 - 1.10x = 28.8
0.89x - 1.10x = 28.8 - 33
-0.21x = - 4.2
x = 4.2 / 0.21
x = 20
20kg of $0.89 candy
(30 - x) = (30 - 20) = 10kg
10kg of $1.10 candy
