Answer:

$\large \boxed{\sf \ \ (-5,0) \ and \ (4,0) \ \ }$

Step-by-step explanation:

Hello,

We need to find the zeroes of

$-0.25x^2-0.25x+5=0\\\\\text{*** multiply by -4 ***} \\ \\x^2+x-20=0\\\\\text{*** the sum of the zeroes is -1 and the product -20=-5x4 ***}\\\\x^2+5x-4x-20=x(x+5)-4(x+5)=(x+5)(x-4)=0\\\\x=4 \ or \ x=-5$

and then g(4)=0 and g(-5)=0

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

PLZ HELP<br> solve for x<br><br> 1 2/3 divided by x = 2 7/9

Convert the mixed numbers to improper fractions.
1 2/3 = 5/3
2 7/9 = 25/9

5/3 ÷ x = 25/9
5/3 = (25/9)x

Multiply both sides by 9/25
5/3 * 9/25 = x
x = (5*9)/(3*25) = 3/5
