Answer:

$b { }^{2} = (61m) {}^{2} - (11m) {}^{2}$

$b {}^{2} = 3721 - 121$

$b {}^{2} = 3600$

$\sqrt{b {}^{2} } = \sqrt{3600}$

$b = 60$

Which number line shows the solution set to this inequality? -2x + 9 < x − 9

kotykmax [81]

Answer:

see below

Step-by-step explanation:

-2x + 9 < x − 9

Add 2x to each side

2x-2x + 9 < 2x+x − 9

9 < 3x-9

Add 9 to each side

9+9 < 3x

18 < 3x

Divide each side by 3

18/3 < 3x/3

6 < x

Answer:

Q 12 roots of the equation

$2x^{2} -6+1=0 \\= (x-\frac{\sqrt{10} }{2})(x+\frac{\sqrt{10} }{2})\\$

∝ = $\frac{\sqrt{10} }{2}$

β = $-\frac{\sqrt{10} }{2}$

no matter if u oppose the root

(i) 2( $\frac{\sqrt{10} }{2}$ ) $(-\frac{\sqrt{10} }{2} )^{2}$ +2 $(\frac{\sqrt{10} }{2} )^{2}$ ( $-\frac{\sqrt{10} }{2}$ )+2(

(ii)( $(\frac{\sqrt{10} }{2})^{2}$ - 3 ( $\frac{\sqrt{10} }{2}$ )( $-\frac{\sqrt{10} }{2}$ ) + ( $(-\frac{\sqrt{10} }{2})^{2}$ ) = $\frac{25}{2}$

Q 13 roots of equation

$4x^{2} -3x-4=0\\\alpha = -0.693\\\beta = 1.443$

the roots of the second equation are

x1 = 1/3(-0.693) = -0.231

x2 = 1/3(1.443) = 0.481

the equation is

(x+0.231)(x-0.481)=0

$x^{2}-\frac{1}{4} x-\frac{1}{9}$

Cedric's basketball team scored fewer than 76 points in their last game. Which of the following inequalities represents the numb

Lelechka [254]

Answer: $n$

Step-by-step explanation:

Although you did not provide the inequalities, the only inequality that can represent the number of points Cedric's basketball team scored in their last game is the one shown below:

Let's call the number of points Cedric's basketball team scored in their last game: $n$ .

You know that Cedric's basketball team scored fewer than 76 points in their last game. "Fewer than" means "less than", which is represented with the symbol < .

Therefore, you can represent the number of points Cedric's basketball team scored in their last game with the following inequality:

$n$
