Consider a family that generates 20 loads of laundry in a week. based on the data in the table, what is the total number of peop

liq [111]

The total number of people in the family that generates 20 loads of laundry in a week is 10.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Let y represent the number of people and x represent the number of laundry loads.

From the table:

y = (1/2)x

For 20 loads:

y = (1/2) * 20 = 10

The total number of people in the family that generates 20 loads of laundry in a week is 10.

Geometry, SEMI-EASY question. I will give brainliest. Just want to double-check.

SashulF [63]

Answer:

Option B

Step-by-step explanation:

Let the point O is the origin.

Then the coordinates of the vertices A,B and C will be,

A → (-12, -8)

B → (-8, 0)

C → (-6, -4)

Rule for the dilation of a point (x, y) by scale factor 'k' about the origin is,

(x, y) → (kx, ky)

By this rule, coordinates of the vertices of the image triangle will be,

If k = $\frac{1}{2}$ ,

A(-12, -8) → A'(-6, -4)

B(-8, 0) → B'(-4, 0)

C(-6, -4) → C'(-3, -2)

From the given options,

Option B is the answer.
