The equation for the expression is M-4=A Because it says Amy is 4 years younger than Marty

Okay so Marty's age is m. That means we have NO IDEA how old he is. He could be 93 years old or 15 years old. We have no clue. Since he could be any number we will symbolize that number with m. Now it says that Amy is four years younger, this means we have to subtract 4 from any age that Marty is...
this will give us: m-4
and that is your answer

Write the equation of the line that passes through (-3,5) and (2, 10) in slope-intercept form.

cupoosta [38]

Answer:

$y=x+8$

Step-by-step explanation:

Slope of straight line can be calculated as

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

Here $(x_1, y_1)=(-3, 5) \ and \ (x_2, y_2) = (2, 10)$

$m =\frac{10-5}{2-(-3)}\\m=1$

Equation of straight line in slope intercept form is

$y-y_1=m(x-x_1)\\y-5=(x+3)$

$y=x+8$

Graph a triangle (LMN) and rotate it 180° around the origin to create triangle L′M′N′.

andreev551 [17]

When a triangle is rotated, it must be rotated through a center of rotation.

Assume the coordinate of LMN is

$\mathbf{L = (1,1)}$

$\mathbf{M = (1,7)}$

$\mathbf{N = (3,6)}$

The rule of 180-degree rotation is:

$\mathbf{(x,y) \to (-x,-y)}$

So, we have:

$\mathbf{L' = (-1,-1)}$

$\mathbf{M' = (-1,-7)}$

$\mathbf{N' = (-3,-6)}$

See attachment for the graphs of LMN and L'M'N

(a) Describe the transformation

When triangle LMN is rotated 180 degrees across the origin, the x and y coordinates of LMN are negated to form triangle L'M'N'

(b) Lines LL' and MM'

The distance between point L and the center of origin is the same as the distance between point M' and the center of origin

Similarly, the distance between point L and the center of origin is the same as the distance between point M' and the center of origin

(c) Line NN'

Line NN' will assume the same characteristics as lines LL' and MM'

A sales associate farms a neighborhood with 750 homes. The owners seem to list their homes every six years. How many listings sh

jenyasd209 [6]

Answer:

50 homes

Step-by-step explanation:

Given that:

Total Number of homes = 750

Years at which home is listed = 6

Thus average listing per year = (total number of homes / years)

Average listing per year = 750 / 6

Average listing per year = 125 homes

If 40% of homes in the neighborhood can be listed :

0.4 * 125

= 50 homes
