What are the x-intercepts of the function f(x) = –2x^2 – 3x + 20? 0 (-4,0) and (5/2, 0)
o (-5/2) and (4,0)
o (-5, 0) and (2, 0)
O (-2, 0) and (5,0)

(5/2,0) and(-4,0)

Step-by-step explanation:

I hope this helps.

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
