Given the system of equations

$\begin{gathered} y=\frac{1}{3}x-8 \\ y=-\frac{5}{3}x-2 \end{gathered}$

The graph shows the solotion of the equations

The point of intersection of the two lines is the solution of the equations

Therefore, the solution is

$(3,-7)$

givi [52]

$x-\ length\\y-\ width\\\\
Perimeter=2x+2y\\\\
175=2x+2y\\
x=2y+6\\\\
175=2(2y+6)+2y\\
175=4y+12+2y\\
175=6y+12\ \ \ |Subtract\ 12\\

y=27,17feet\\\\
x=2*27,17+6=60,34feet\\\\
Length=60,34 \ feet\ and\ width=27,17\ feet.$

sin²Ø+cos²Ø/sin²Ø
1/sin²Ø
cosec²Ø

Putting root over

a quadratic equation has zero real number solutions. which could be the discriminant value associated with this equation? a. –5

Flauer [41]

Answer: Option 'a' is correct.

Step-by-step explanation:

As we know about the discriminant value i.e.

if we have given a quadratic equation :

$ax^2+bx+c=0$

then,

discriminant value will be

$b^2-4ac$

There are 3 properties regarding discriminant value as follows:

$1)b^2-4ac>0\\\\means,\\\\\text{ there exists real zeros}\\\\2)b^2-4ac=0\\\\means,\\\\\text{ there exists equal zeroes}\\\\3)b^2-4ac$

So, here we need a zero real number solutions i.e. there does not exists any real number.

So,

$b^2-4ac=-5$

Hence, Option'a' is correct.
