Answer:
P(5, 0 )
Step-by-step explanation:
Where the line crosses the x- axis the y- coordinate of the point P is zero.
Substitute y = 0 into the equation and solve for x
2x + 3(0) - 10 = 0 , that is
2x - 10 = 0 ( add 10 to both sides )
2x = 10 ( divide both sides by 2 )
x = 5
Thus P = (5, 0 )

Answer:
EASY. y = 4/7x+3
Step-by-step explanation:
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
The bottom one is the correct answer.
