Seven is 14 less than twice a number

77julia77 [94]

Answer:

This fraction cannot be simplified down.

Step-by-step explanation:

Although the fraction cannot be simplified it can be divided into mixed number form which is what I assume you meant by simplified.

$\frac{16}{7}$

Multiply by 2 and subtract 16 by 14

$7\times2=14$

$16-14=2$

$\frac{16}{7} =2r$

Keep the denominator the same.

$\frac{16}{7} = 2\frac{2}{7}$

$=2\frac{2}{7}$

Hope this helps.

Pls pls, pls help me with my math

Neko [114]

Answer:

Obviously only D is true

Note 2 x - 1 < 10 can be rewritten

2 X < 11 and

x < 5.5

So all of the values in the set would have to be less than 5.5

. The estimate regression equation for a model involving two independent variables and 10 observations follows.y = 29.1270 + 0.5

beks73 [17]

Answer:

b) y = 289.815 when $x_1 = 180 \text{ and } x_2 = 310$

Step-by-step explanation:

We are given the following information in the question:

$y = 29.1270 + 0.5906x_1 + 0.4980x_2$

where y is the dependent variable,

$x_1, x_2$ are the independent variable.

The multiple regression equation is of the form:

$y = b_0 + b_1x_1 + b_2x_2$

where,

$b_0$ : is the intercept of the equation and is the value of dependent variable when all the independent variable are zero.

$b_1$ : It is the slope coefficient of the independent variable $x_1$ .

$b_2$ : It is the slope coefficient of the independent variable $x_2$ .

The regression coefficient in multiple regression is the slope of the linear relationship between the dependent and the part of a predictor variable that is independent of all other predictor variables.

Comparing the equations, we get:

$b_1 = 0.5906\\b_2 = 0.4980$

This means holding $x_2$ constant, a change of one in $x_1$ is associated with a change of 0.5906 in the dependent variable.

This means holding $x_1$ constant, a change of 1 in $x_2$ is associated with a change of 0.4980 in the dependent variable.

b) We have to estimate the value of y

$y = 29.1270 + 0.5906(180) + 0.4980(310) = 289.815$

Write a complete sentence that states the type of transformation that was performed and explains the transformation in detail. Q

Cerrena [4.2K]

The type of transformation that has happened is a translation. Translation is when the image's size nor shape changes after transformation. every point in the image moves the same distance in the same direction.
the equation for the translation mentioned is;
T4, -5(x,y)
this means that every point in the image has moved down by 5 units and moved to the right by 4 units.
Point A to Point E
Point A - (-4,-1)
after translation (x+4, y-5) = (-4+4,-1-5)
= (0,-6) these are the coordinates of point E.
the other three points too have moved the same distance and direction as point A did.
