One x-intercept for a parabola is at the point (1,0). Use the factor method to find the other x-intercept for the parabola defin

Hoochie [10]

First simplify the equation of parabola $y=-5x^2+15x-10$ in the following way:
$D=(15)^2-4\cdot (-5) \cdot (-10)=225-200=25, \\ \sqrt{D}=5, \\ x_{1,2} = \dfrac{-15\pm 5}{2\cdot(-5)} = 2, 1 \\ -5x^2+15x-10=-5(x-1)(x-2), \\ y=-5(x-1)(x-2)$ .
You can see that if x=1 or x=2, then y=0. Two points of intersection with x-axis are (1,0) and (2,0).

the first three terms of an arithmetic progression is (x + 1), (4 x - 2) and 6 x - 3 if the last term is 18 find the value of x

lbvjy [14]

Answer:

Step-by-step explanation:

Since it is AP, the common difference is same for any term:

(4x - 2) - (x + 1) = (6x - 3) - (4x - 2)
3x - 3 = 2x -1
3x - 2x = 3 - 1
x= 2

The first 3 terms are:

3, 6, 9

Since the last term is 18, it means this AP has 6 terms:

{3, 6, 9, 12, 15, 18}

Answer: as we need to find the value of x only, it is = 2
