Encuentra la pendiente de la recta formada por los puntos A( 3 , -2 ) Y B( -5 , 3 )

QveST [7]

Answer:

$\frac{5}{-8}$ or -0.625

Step-by-step explanation:

The slope formula is as shown:

$m=\frac{y_{2} -y_{1} }{x_{2} -x_{1}}$

We can have A = ( $x_{1}$ , $y_{1}$ ) and B = ( $x_{2}$ , $y_{2}$ ).

We can hence plug in the values into the formula to get $m=\frac{3-(-2)}{-5-3}$ .

As we simplify, the negatives on the top row cancel out to give us an addition sign instead and we add them.

$m=\frac{5}{-8}$

Brainliest would be appreciated!

1. What is the solution of n² – 49 = 0? (1 point)

maks197457 [2]

Answer:

1. $n=\pm7$

2. $x=\pm7i[tex]3.[tex]\pm 12x =a$

4. 22

Step-by-step explanation:

1. $n^2 - 49 = 0$

$n^2 =49$

$n= \sqrt{49}$

$n=\pm7$

2. $x^2+64 = 0$

$x^2 =-64$

$x= \sqrt{49}$

$x=\pm7i[tex]3. Area of square = [tex]a^{2}$

Where a is the side

We are given an area o square = $144x^{2}$

So, $144x^{2}=a^{2}$

$\sqrt{144x^{2}}=a$

$\pm 12x =a$

4. We are given that the solution of quadratic equation -9 and 9

So, equation becomes:

$(x+9)(x-9)=0$

$x^2- 81=0$

So, in the given equation $x^2 + z = 103$

z should be the number from which if we subtract 103 so we get 81

Substitute z = 22

$x^2 + 22 = 103$

$x^2 + 22 -103=0$

$x^2 -81=0$

Thus the value of z is 22
