Writing Exercises

Rudik [331]

Answer: a monomial has one term, binomial has 2 terms, and trinomial has 3.

Step-by-step explanation:

using a bit of greek and latin roots, we can observe that all 3 terms have the same suffix of nomial in them. From this, we know that mono means one, bino means two, and tri means 3. Fun fact, there's also polynomial (if you did or didn't know), which is multiple terms more than 3.

Find the real and/or imaginary solutions by factoring

Leya [2.2K]

Here is number 7:
${x}^{2} - 11x = - 24 \\ {x}^{2} - 11x + 24 = 0 \\ (x - 3)(x - 8) = 0 \\ x = 3 \: and \: 8$
Here is number 8:

$3 {x}^{3} + 3 {x}^{2} = 27x \\ 3 {x}^{3} + 3 {x}^{2} - 27x = 0 \\ 3x( {x }^{2} + x - 9) = 0 \\ x = 0 \: and \: two \: more \: solutions \: shown \: below.$
Use the quadratic formula to find the other two solutions:

$x = \frac{ - 1 + - \sqrt{ {1}^{2} - 4(1)( - 9) } }{2(1)} \\ x = \frac{ - 1 + \sqrt{37} }{2} \\ x = \frac{ - 1 - \sqrt{37} }{2}$

if 2/3 of the girls in class have brown eyes and one fourth of the girls have blue eyes what fraction of girls in class have nei

Virty [35]

1/3: doesn't have brown eyes
3/4: doesn't have blue eyes

1/3 x 3/4 = 1/4

So, 1/4 of the class has neither brown or blue eyes.

Step-by-step explanation:

I recomend using desmos to show the relashinship

If you don't want to, thwn do this

Preimage $(0-4,1+3),(4-4,6+3),(-5-4,-1+3)$

Since we are finding z, we only use the final cordinates

z'=(-9,2)
