2x2 – 9x + 2 = –1
Reika [66]

Answer:

C)  The discriminant is greater than 0, so there are two real roots

Step-by-step explanation:

<u>Discriminant</u>

b^2-4ac\quad\textsf{when}\:ax^2+bx+c=0

\textsf{when }\:b^2-4ac > 0 \implies \textsf{two real roots}

\textsf{when }\:b^2-4ac=0 \implies \textsf{one real root}

\textsf{when }\:b^2-4ac < 0 \implies \textsf{no real roots}

2x^2-9x+2=-1

\implies 2x^2-9x+3=0

\implies a=2, b=-9, c=3

\begin{aligned}b^2-4ac &=(-9)^2-4(2)(3)\\& =81-24\\&=57 > 0\implies \textsf{two real roots}\end{aligned}

g100num [7]

Answer:

x = 30

y = 15

Step-by-step explanation:

<u><em>All the angles are </em></u><u><em>90°</em></u><u><em>, so set 6y and 3x equal to 90, like so:</em></u>

6y = 90

<u><em>Divide both sides by 6:</em></u>

y = 15

<u>Solving for x:</u>

3x = 90

<em><u>Divide both sides by 3:</u></em>

x = 30
