when x = -1

y= 3x - 1

3(-1) - 1

-3 -1

-4

when x = 0

y = 3x - 1

3(0) - 1

0 - 1

-1

when x = 2

y = 3x -1

Step-by-step explanation:

y = 3x - 1

Putting x = -1

y = 3( - 1) - 1

y =  - 3 - 1

y =  - 4

Putting x = 0

y = 3(0) - 1

y = 0- 1

y = -1

Putting x = 2

y = 3(2) - 1

y = 6 - 1

y = 5

How many different pairs of parallel edges are there on a rectangular solid?
Monica [59]

Answer:

18

Step-by-step explanation:

A rectangular prism has four parallel edges along its length, four parallel edges along its width, and four parallel edges along its height.

We want to know how many different pairs of parallel edges there are.  Starting with the length, the number of unique pairs is:

₄C₂ = 6

The same is true for the width and height.  So the total number of different pairs of parallel edges is:

3 × 6 = 18

Solve S= lw + wh+ lh for h. Hint: Use the distributive property to factor out h.<br> the<br> vcloc
Ostrovityanka [42]

Answer:

{ \rm{S = lw + wh + lh}}

• Group the h terms by organised term arrangement :

{ \rm{S = (wh + lh) + lw}}

• Then using distributive property, factorise out the value h so that the reverse is true.

{ \rm{S = h(w + l) + lw}}

• for the variable "lw", divide it by h in order to add it to the bracket of (w + l). Make sure the reverse is true:

{ \rm{S = h(w + l) + h( \frac{lw}{h} )}} \\

• finally, completely factorise out the value h

\hookrightarrow \: \: { \boxed{ \boxed { \rm{ \:  \: S = h(w + l +  \frac{lw}{h} ) \:  \: }}}}
