Answer:

B; x = 8

Step-by-step explanation:

I think I understand what the picture is saying. So,

On the left hand side, the x's and +1's represent the following expression:

$2x +5$ .

On the right hand side, the x's and -1's represent the following expression:

$3x -3$ .

Put these two together and you get the following equation:

$2x +5$ = $3x -3$

First, Solve for x:

8 = x

So, when solving the equation, x is equal to 8

Answer:

Here, BRX and NJY are two triangles in which,

BR = 30 cm, RX = 40 cm, BX = 60 cm, NJ = 15 cm, JY = 20 cm and NY = 30 cm,

Also, m∠B = m∠N, m∠R = m∠J and m∠X = m∠Y,

By the property of congruence,

$\angle B \cong \angle N$ , $\angle R \cong \angle J$ and $\angle X \cong \angle Y$

Thus, By AAA similarity postulate,

$\triangle BRX\sim \triangle NJY$

Hence, proved.

Write an equation for the 4th degree polynomial graphed below. Use k if your leading coefficient is positive and −k if your lead

Afina-wow [57]

Ho ho ho, lets get this party started
ok so I'm just really excited to use this stuff that I just learned

so

multiplicites
if a root or zero has an even multilicity, the graph bounces on that root
if the root or zero has an odd multiplicty, the graph goes through that root

so
roots are
-1
2
4
multiplicty is how many times it repeats
2 has even multiplity
we just do 2 is odd and 1 is even so
for roots, r1 and r2, the facotrs would be
(x-r1)(x-r2)
so
(x-(-1))^1(x-2)^2(x-4)
(x+1)(x-2)^2(x-4)
this is a 4th degre equaton
normally, it is goig from top right to top left
it is upside down
theefor it has negative leading coefient

y=-k(x+1)(x-4)(x-2)^2

masya89 [10]

Answer:

A. Predict a dichotomous variable from continuous or dichotomous variables.

Step-by-step explanation:

Logistic regression is used when you want to predict a dichotomous variable from continuous or dichotomous variables.

Mathematically, it is given by the expression;

Logistic regression $y$ with $x_{1}$ , $x_{2}$ ........ $x_{n}$

Where;

y represents the dichotomous dependent variable.

$x_{1}$ , $x_{2}$ ........ $x_{n}$ represents the predictable variables, which are categorical in nature such as alive or dead, win or lose, sick or healthy, pass or fail, etc.
