To see if the point is on the line, plug in one of the point values to see if it equals out.
y = 4x - 2 I will plug in 1 for x to see if y does = 3
y = 4(1) - 2
y = 4 - 2
y = 2 so (1, 2)
Dinesh is not correct because the point on the line when x = 1 is (1, 2) not (1, 3)
Answer:
one pound of banana costs $0.59
Step-by-step explanation:
Divide the cost (1.18) by the pounds (2)
1.18/2 = 0.59
Sqrt(x^2) = sqrt(20)
x = +2sqrt(5)
x = -2sqrt(5)
x1 = (- 0 + sqrt(0^2 - 4*1*(-20))) / (2*1)
X2 = (-0 - sqrt(0^2 - 4*1*(-20))) / (2*1)
Hopes this helps:
Answer: x = -10/7
1. Simplify 2 • 2 to 4
4 + 7x + 6 = 0
2. Simplify 4 + 7x + 6 to 7x + 10.
7x + 10 = 0
3. Subtract 10 from both sides.
7x = -10
4. Divide both sides by 7.
X = -10/7
Answer: 6 book set = 69.95
