Answer:

On the first page: The two trapezoids on the left are similar.

On the second page: The two rectangles on the right are similar.

Step-by-step explanation:

Similar shapes have corresponding sides in a constant proportion.

The trapezoids on the left of the first page have a scale factor of 2.5 between the smaller and larger trapezoid between all corresponding sides, therefore are similar.

The rectangles on the right of the second page have a scale factor of 1.6 between the smaller and larger rectangle between all corresponding sides, therefore are similar.

What is the slope-intercept form of 12x + 4y = 32?

valentina_108 [34]

Answer:

D. y=-3x+8

Step-by-step explanation:

first, get the 12x on the other side of the equation

12x+4y-12x=32-12x

4y=-12x+32

divide the equation by four

y=-3x+8

Hope this helps!

Find the missing end point if H is the midpoint of PS. P(2,5) and H (3,4) find S (endpoint)

RUDIKE [14]

Answer:

(4,3)

Step-by-step explanation:

To find the midpoint add the end points and divide by 2

P(2,5) S ( sx, sy) and the midpoint is and H (3,4)

X coordinate

( 2+ sx) /2 = 3

Multiply each side by 2

2+sx = 3*2

2+sx = 6

Subtract 2

sx = 4

Y coordinate

( 5+ sy) /2 = 4

Multiply each side by 2

5+sy = 4*2

5+sy = 8

Subtract 5

sy = 3

The end point is

(4,3)

<em>Independent variables are variables of a quantity that are not affected by any conditions. </em>

<em>Dependent variables are variables of a quantity that change if conditions relative to that variable changes.</em>

For example, we generally we take x as independent variable by x variable and dependent variable by y variable.

To find the rate of change we get two values of independent variable (x's) and two values of dependent variables (y's) to get two coordinates in form of

(x,1,y1) and (x2,y2).

<h3>And we can find the rate of change by applying slope formula</h3>

$m= \frac{y_2-y_1}{x_2-x_1}$ .
