1. Slope=9
2. x-intercept = 7/9 = 0.77778
3. y-intercept = 7/-1= -7.00000
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: 9*X-Y-(7)=0

Select the two values of x that are roots of this equation. 2x^2-11x+15=0
zaharov [31]

Hey there! :)

Answer:

x = 5/2 and 3.

Step-by-step explanation:

Factor the equation. Find numbers that will sum up to -11 involving the coefficient of 2, and that multiply into 15.

2x² - 11x + 15 = 0

(2x - 5)(x - 3) = 0

Use the Zero Product Property to solve for the roots of this equation:

2x - 5 = 0

2x = 5

x = 5/2

----------

x - 3 = 0

x = 3.

Therefore, the two values of x that are roots of this equation are:

x = 5/2 and 3.
