Use the quadratic formula to find the solutions for..<br> y = 2x^2 - 9x + 5.

Yakvenalex [24]

Answer: $x=\frac{9}{4}-\frac{\sqrt{41} }{4} \\x=\frac{9}{4}+\frac{\sqrt{41} }{4}$

Step-by-step explanation:

$2x^2-9x+5$

a=2

b=-9

c=5

$x=\frac{-b\frac{+}{}\sqrt{b^2-4ac} }{2a}$

$x=\frac{-(-9)\frac{+}{}\sqrt{(-9)^2-4(2)(5)} }{2(2)}$

$x=\frac{9\frac{+}{}\sqrt{81-40} }{4}$

$x=\frac{9\frac{+}{}\sqrt{41} }{4}$

$x=\frac{9}{4}-\frac{\sqrt{41} }{4} \\x=\frac{9}{4}+\frac{\sqrt{41} }{4}$

Phyllis solved the compound inequality 16 < 2(3x – 1) < 28. She began by first breaking the inequality into two separate i

poizon [28]

16<2(3x-1)<28 divide all terms by 2

8<3x-1<14 add 1 to all terms

9<3x<15 divide all terms by 3

3<x<5

x=(3,5) in interval notation

On a number line, it would be a line segment from 3 to 5 with open circles at 3 and 5.

On a coordinate system graph, it would be an infinitely high shaded plane between the vertical lines x=3 and x=5
