Rewrite, using the distributive

kodGreya [7K]

The distributive property is basically gonna be distributing the outside number among the inside numbers

Think of it like this instead: (3 • 2x) + (3 • 6)

Your answer for this would be 6x+18
Hope this helps!

What is the slope of the line that passes through the pairs of points (-6,8) (2'3)

Alecsey [184]

Im pretty sure the answer is D, because if i used the right formula,
$\frac{y2 - y1}{x2 - x1}$
you should get this in the formula
$\frac{8 - 3}{2 - ( - 6)}$
$\frac{5}{8}$
a 2 subtracting a negative 6 makes it a positive, meaning your just adding 6 plus2, to get 8

Delia is a graphic designer who charges an hourly rate. She made the graph to show her total earnings for various numbers of hou

stich3 [128]

Answer:

approximately 7 hours

see the explanation

Step-by-step explanation:

The picture of the question in the attached figure

Let

x ----> the time worked in hours

y ----> the amount earning in dollars

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>

In this problem we have a proportional relationship

step 1

Find approximately how many hours would it take Delia to earn $250 ?

Looking at the graph

For y=$250 The value of x is approximately 7 hours

see the attached figure N 2

step 2

Find the exact value

from the graph take the point (5,175)

Find the value of k

$k=\frac{y}{x}$ ----> $k=\frac{175}{5}=\$35\ per\ hour$

The linear equation is

$y=35x$

For y=$250

substitute

$250=35x$

solve for x

$x=7.14\ hours$

Mrs.jackson bought 7 dozen eggs if each student is given the same out of eggs how many eggs are left

nikdorinn [45]

Without knowing the number of students she has, you will not be able to answer the question correctly. There are 12 eggs in one dozen. 12 x 7 dozen = 84 eggs. You still need to know the number of students.
