Answer:

Step-by-step explanation:

set 30

1) 90-52 = x

38 = x

2) 90 -15-25=x

50 = x

set 31

1)   t = 3m

m = independent

t = dependent

 m    t

\left[\begin{array}{ccc}1 & 3\\2 & 6\\3 & 9\\4&12\\5&15\\6&18\end{array}\right]

2)

m = 25d

d = independent

m = dependent

 m     d

\left[\begin{array}{ccc}1&25\\2&50\\3&75\\4&100\\5&125\\6&150\\7&175\end{array}\right]

Does the data in the table represent a direct variation or an inverse variation? Write an equation to model the data in the tabl
lukranit [14]

Answer:

- Inverse Variation

- Equation: XY = 12

Step-by-step explanation:

Given

X-> 2 | 4 | 8 | 12

Y-> 6 | 3 | 3/2 | 1

Required

- State the type of variation the table represents

- Determine the equation to model the data

To check for type of variation; we'll make use of trial by error method.

To start with; We'll check for direct variation.

This is done using the following expression;

Y = kXwhere k is the constant of variation

Make k the subject of formula

k = \frac{Y}{X}

When Y = 6, X= 2

K = \frac{6}{2} = 3

When Y = 3, X = 4

K = \frac{3}{4}

There's no need to check further as both values of k are not equal

To check for inverse variation;

Y = \frac{k}{X}

Make k the subject of formula

k = YX

When Y = 6, X= 2

K = 6 * 2 = 12

When Y = 3, X = 4

K = 3 * 4 = 12

When Y = 3/2; X = 8

K = \frac{3}{2} * 8 = \frac{24}{2} = 12

When Y = 1, X = 12

K = !2 * 1 = 12

Note that for all values of X and Y, K remains constant;

Hence, the table represents an inverse direction

To determine the equation;

We make use of  k = YX

Substitute 12 for k

So, the equation becomes

12 = XY

Reorder

XY = 12

Hence, the equation is XY = 12

This line segment will be dilated with the point of dilation at (4,1) and scale factor of 2. What is the x-coordinate of one of
IgorLugansk [536]

Answer:

<h3>8</h3>

Step-by-step explanation:

If a coordinate point (x, y) is dilated by a factor k, then the resulting coordinate will be (kx, ky)

Given the coordinate (4,1), if this coordinate is dilated by a factor of 2 then the new coordinate points will be at (2(4), 2(1))

New point = (8, 2)

Hence  x-coordinate of one of the the end point of the dilated segment is 8
