22. Which equation has solutions of -2 and 3?
A. y=x²+x-6
B. y=x²-x-6
C. y = x + 5x + 6
D. y = x2-5x+6

  B. y=x²-x-6

Step-by-step explanation:

Consider the product ...

  0 = (x -a)(x -b) = x² -(a+b)x +ab

This equation has solutions x=a and x=b. You will note that ...

For solutions of -2 and 3, the constant will be (-2)(3) = -6. This eliminates choices C and D.

The sum of the solutions is -2+3 = 1, so the coefficient of x is -1, matching choice B.

answer: the equation matches the regression

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
