The system equations 2y=14-2x and y=-x+7

Mathematics
1 answer:
Artemon [7]2 years ago
6 0

Answer:

Hey there!

When we are given what one of our variables is equal to, we can easily solve the system of equations via substitution, which is where we take the variable value, plug it into the other equation, and solve for the other variable.

In this case, we just take our value for y and plug it in for the value for y in the first equation and solve for x.

2(-x+7)=14-2x

-2x+14=14-2x

-2x=-2x

x=x

As we can see, there are infinitely many solutions to this first equation, which means that there is no possible way to solve for y because x has infinitely many solutions, so there are infinitely many solutions to this system of equations, because they are both the same line.

I hope this helps! :D

Answer:

\frac{1}{27}

Step-by-step explanation:

Using the rule of exponents

\frac{a^{m} }{a^{n} } with n > m

= \frac{1}{a^{(n-m)} }, thus

\frac{3^{5} }{3^{8} } = \frac{1}{3^{(8-5)} } = \frac{1}{3^{3} } = \frac{1}{27}

ODS

a. $275.00 b. $325.00 c. $250.00 d. $300.00

Answer:

d. $300.00

Step-by-step explanation:

Given that a cosmetologist must double her salary before the employer can realize any profit from  his/her work, for Miss. Mead to realize $50.00 profit on her work, you would have to determine the amount that doubles the salary of the cosmetologist and add the $50 needed as profit:

Salary= $125*2=$250

$250+$50= $300

According to this, the answer is that for Mead to realize $50.00 profit on her work, Miss. Brown must take $300.
