Solve following | 2x + 9 = 15

vivado [14]

Answer:

x₁ = 3

x₂ = - 12

Step-by-step explanation:

Hi there !

| 2x + 9 | = 15

1.

2x + 9 = 15

2x = 15 - 9

2x = 6

x = 6 : 2

x₁ = 3

2.

2x + 9 = - 15

2x = - 15 - 9

2x = - 24

x = - 24 : 2

x₂ = - 12

Good luck !

Amir stands on a balcony and throws a ball to his dog, who is at ground level. The ball's height (in meters above the ground), x

Y_Kistochka [10]

When the ball hit the ground, the height of the ball will be zero. So using the value of h(x) as zero in the given equation, we can find the time in which the ball will hit the ground.

$0=-(x-2)^{2}+16 \\ \\ 
(x-2)^{2}=16 \\ \\ 
x-2= \sqrt{16} \\ \\ 
x-2=4 \\ \\ 
x=6$

This means the ball will hit the ground 6 seconds after Amir threw it

Let Upper A equals left bracket Start 2 By 2 Matrix 1st Row 1st Column negative 2 2nd Column 4 2nd Row 1st Column 1 2nd Column 3

vagabundo [1.1K]

Answer:

not

Step-by-step explanation:

$\left[\begin{array}{ccc}-2&4\\1&3\end{array}\right] *\left[\begin{array}{ccc}-2&1\\3&7\end{array}\right]=$

First is A and Second is B

Let's find A*B

$\left[\begin{array}{ccc}-2(-2)+4*3&-2*1+4*7\\1(-2)+3*3&1*1+3*7\end{array}\right] =\left[\begin{array}{ccc}16&26\\7&22\end{array}\right]$

$\left[\begin{array}{ccc}-2&1\\3&7\end{array}\right] \left[\begin{array}{ccc}-2&4\\1&3\end{array}\right] =$

Now let's find B*A

$\left[\begin{array}{ccc}-2(-2)+1*1&-2*4+1*3\\3(-2)+7*1&3*4+7*3\end{array}\right] =\left[\begin{array}{ccc}5&-5\\1&23\end{array}\right]$
