Answer:

Step-by-step explanation:

She has 36 yards of material.

She needs 1 1/3 + 1/6 for each place setting

1/3 + 1/6 = 1/2

She needs 1 1/2 yards of material for each setting

1 1/2 = 1.5

She has to divide 36 by 1.5. If there is anything left over, it becomes scrap to be used for her next project.

You can use the following formula

# settings = Total material/setting length
# settings = 36/1.5 = 24

She can make 24 settings with nothing left over.

The volume of a rectangular prism is (x^3-3x^2+5x-3)/(x^3-2)

Trava [24]

The volume of a rectangular prism = its base area * height

substitute:

x3 – 3x2 + 5x – 3 = (x2 – 2) * h

h= (x3 – 3x2 + 5x – 3)/(x2 – 2)

so you can use the long division

Write an equation in slope-intercept form of the line that passes through (-1, 4) and (0, 2)

MrMuchimi

Answer:

y = -2x + 2

General Formulas and Concepts

Pre-Alg

Order of Operations: BPEMDAS

Algebra I

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

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

Step-by-step explanation:

Step 1: Define

Point (-1, 4)

y-intercept (0, 2)

Step 2: Find slope m

Substitute: $m=\frac{2-4}{0+1}$
Subtract/Add: $m=\frac{-2}{1}$
Divide: $m=-2$

Step 3: Write linear equation

y = -2x + 2
