1. the value of y varies directly with x, and y = 48 when x = 16. find y when x = 176. y = 3 y = 368 y = 58.7 y = 528 2.write an equation in slope-intercept form of the line with slope 3/4 that contains the point (−4,1). y=3/4x+3 y=3/4x+1 y=3/4x−4 y=3/4x+4 3. tell whether the equation 4x + y = 3 represents a direct variation. if so, identify the constant of variation. direct variation, k = −1/4 direct variation, k = 3 direct variation; k = −4 not a direct variation.

Part 1)

Part 2)

Part 3) Not a direct variation

Step-by-step explanation:

Part 1) we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or

In this problem we have

Find the constant of proportionality k

substitute the values

The equation of the direct variation is equal to

so

For

Part 2) we know that

the equation of the line in slope-intercept form is equal to

where

m is the slope

b is the y-coordinate of the y-intercept

we have

Point

substitute the values in the equation and solve for b

the equation is equal to

Part 3) Tell whether the equation represents a direct variation

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form or

In the direct variation the constant of proportionality k is equal to the slope of the line and the line passes through the origin

In the linear equation   the line does not passes through the origin

so

Not a direct variation

the answer is thin because within context, the stanza concludes the and frail tone the people have toward each other, and the fact that it would be thin, makes the most sense compared to "pliable" or "not hard or firm to the touch". hope this , good luck.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
