When x = -1, y = - 3 ((-1)^2-4)

When x = 0, y = -4 ((0)^2-4)

When x = 5, y = 21 ((5)^2-4)

When x = 13 y = 165 ((13)^2-4)

You just substitute the values of X into the equation

The ratio of boys to girls in the entire 6th grade is 3 to 2. Given this ratio, which two class compositions are possible?

gtnhenbr [62]

Answer:

There's an infinite number of possible answers because there might be any multiplication of 3 for boys and any multiplication of 2 for girls. So, for example:

There might be 3 boys and 2 girls.

There might be 6 boys and 4 girls.

There might be 9 boys and 6 girls.

There might be 12 boys and 8 girls.

etc...

In each case the ratio stays the same - 3 : 2.

Of course there probably can't be more than a few dozens of people in one class, but theoretically we can raise the numbers up to infinite.

Step-by-step explanation:hope this help.

Solve the quadratic equation by factoring 9x2+24+20=4

AnnyKZ [126]

Answer:

Final answer is $x=-\frac{4}{3}$ and $x=-\frac{4}{3}$ .

Step-by-step explanation:

Given equation is $9x^2+24x+20=4$ .

Now we need to solve that by factoring.

$9x^2+24x+20=4$

$9x^2+24x+20-4=0$

$9x^2+24x+16=0$

$9x^2+12x+12x+16=0$

$3x(3x+4)+4(3x+4)=0$

$(3x+4)(3x+4)=0$

$(3x+4)=0$ , $(3x+4)=0$

$3x+4=0$ , $3x+4=0$

$3x=-4$ , $3x=-4$

$x=-\frac{4}{3}$ , $x=-\frac{4}{3}$

Hence final answer is $x=-\frac{4}{3}$ and $x=-\frac{4}{3}$ .
