Using distributive property

Mathematics
1 answer:
Hoochie [10]3 years ago
3 0

Answer:

Step-by-step:  Step 1: Add -19x to both sides

 48x-6y+3+-19x=19x+15y+-19x

29x-6y+3=15y

Step 2: Add 6y to both sides

29x-6y+3+6y=15y+6y

29x+3=21y

Step 3: Add -3 to both sides

29x+3+-3=21y+-3

29x=21y-3

Step 4: Divide both sides by 29

29x/29=21y-3/29

x=21/29y+ -3/29

A company offers its employees the choice of two contracts. The first contract gives an initial salary of 15000/year rising it b
sladkih [1.3K]
To answer this question, start by identifying the total amount of income after 5 years for the first contract.
Since you start with 15,000 and get 1000 more each year, write an expression that represents this relationship.
15000 + 1000(5)

Multiply the parenthesis to begin to simplify your expression.
This leaves you with:
15000 + 5000

Add to find the total salary after five years with the first contract.
This ends up with:
$20,000

For the second contract, you have a diffferent rate of increase. Start by finding what one percent of the initial salary is. To do this, divide 14000 by 100.
14000/100 = 140
Then to find ten percent, multiply that number by 10.
140 x 10 =1400

So, each year you add 1400 dollars to the salary.
Now, using this information, set up an expression to model the salary for contract 2 after 5 years.
This should leave you with:
14000 + 1400(5)

Begin to simplify by multiplying what’s in the parenthesis.
1400 x 5 = 7000
Now rewrite your expression:
14000 + 7000

Add to find the total salary after 5 years with contract 2.
14000 + 7000 = 21000

So the salary with contract 2 is $21,000.



So, since $21000 is $1000 more than just $20000, contract 2 is the better option. I hope this helps! :)

The sum of a number and 3 times its reciprocal is -4.Find the number
Butoxors [25]

Answer:

x = -1 or x = -3

Step-by-step explanation:

x + 3/x = -4

x² + 3 = -4x

x² + 4x + 3 = 0

(x + 1) (x + 3) = 0

x = -1 or x = -3

check: (-1) + (3/-1) = -1 - 3 = -4

           (-3) + (3/(-3)) = -3 -1 = 14

The y-intercept of the line whose equation is 7x - 4y = 8 is what
Anni [7]
The y intercept is when x is 0. So, we have to plug in 0 for x. You can do this in many different ways as well.
7(0)-4y=8
-4y=8
Divide both sides by -4.
Y=-2
So, the Y intercept is -2 (0,-2).

Evaluate<br> 8.2+(3+0<br> ——<br> 3
jenyasd209 [6]

Answer:

11.2

Step-by-step explanation:

well i'm guessing that you didn't finish you parenthesis and if you did they would be around the 0 and 3 so 3 plus 0 is 3 and 3 plus 8.2 is 11.2 so I believe your answer is 11.2.  Sorry if it is wrong the question didn't really make sense.
