Answer:

6x -16

Step-by-step explanation:

f(x) = 6x + 2

f(x-3) =

Replace x with x-3

f(x) = 6(x-3) + 2

Distribute

= 6x - 18 +2

= 6x -16

What is the equation of this line?

elena-14-01-66 [18.8K]

Answer:

A) y = 4/3 x - 1/3

Step-by-step explanation:

(4,5) and (-2,-3)

Slope = (5 + 3)/(4 + 2)

= 8/6

= 4/3

Equation

y + 3 = 4/3(x + 2)

y + 3 = 4/3 x + 8/3

y = 4/3 x + 8/3 - 9/3

y = 4/3 x - 1/3

Answer:

y = 4/3 x - 1/3

A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. The

Delvig [45]

10 small boxes and 11 large boxes were shipped.

Step-by-step explanation:

Given,

Total boxes shipped = 21

Total volume of shipped boxes = 342 cubic feet

Volume of each small box = 10 cubic feet

Volume of each large box = 22 cubic feet

Let,

Number of small boxes = x

Number of large boxes = y

According to given statement;

x+y=21 Eqn 1

10x+22y=342 Eqn 2

Multiplying Eqn 1 by 10

$10(x+y=21)\\10x+10y=210\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(10x+22y)-(10x+10y)=342-210\\10x+22y-10x-10y=132\\12y=132$

Dividing both sides by 12

$\frac{12y}{12}=\frac{132}{12}\\y=11$

Putting y=11 in Eqn 1

$x+11=21\\x=21-11\\x=10$

10 small boxes and 11 large boxes were shipped.
