Answer:

12

Step-by-step explanation:

Distribute the negative which would get your 3x + 6 -3x + 6. The 3x would cancel out and you would add 6+6 = 12

Answer:

12

Step-by-step explanation:

1. Write the problem.

(3x+6)-(3x-6)

2. Put a 1 after the subtraction/negative sign because there is technically a 1 after the subtraction/negative sign between the two phrases.

= (3x+6)-1(3x-6)

3. Distribute the -1 to the 2nd part.

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

4. Simplify the equation.

= 3x+6-3x+6

5. Find like terms.

= 3x<u>+6</u>-3x<u>+6</u>

The 3x and -3x cancel each other out, leaving <u>6+6</u>.

So, the answer is 12.

Hope this helps you understand a little more!!

A salesperson's weekly paycheck is 40% more than a second salesperson's paycheck. The two paychecks total $1075. Find the amount
BlackZzzverrR [31]
X is gonna be the normal paycheck

0.45x+x=1075

= 0.40x+x=1075

= 1.4x=1075

x= 1075/1.4

x=767.85   the normal paycheck price

1075.00-767.85= 307.15

so a saleperson weekly paycheck is 307.15 dollars more 

hope this helps

Find the x- and y-intercepts for the linear equation –3x + 4y = 24.
Sav [38]

Answer:

x- intercept = - 8, y- intercept = 6

Step-by-step explanation:

To find the x- intercept let y = 0 and solve for x

- 3x + 4(0) = 24

- 3x = 24 ( divide both sides by - 3 )

x = - 8 ← x- intercept

To find the y- intercept let x = 0 and solve for y

- 3(0) + 4y = 24

4y = 24 ( divide both sides by 4 )

y = 6 ← y- intercept

The weight, in pounds, of a newborn baby t months after birth can be modeled by W. A graph of W is shown below. Write an equatio
Agata [3.3K]

the First we need to choose two points in the graph

(0,6)=(t1,w1)

(1,7)=(t2,w2)

the variables are t and w

then we can calculate the slope

m=\frac{w2-w1}{t2-t1}=\frac{7-6}{1-0}=\frac{1}{1}=1

the equation of W is

where

m=1 ---> slope

b=6 ---> y-intercept

\begin{gathered} W=mt+b \\ W=1\cdot t+6 \\ W=t+6 \end{gathered}

the answers are

W=t+6

slope of the function 1

the answer is the third option
