How many solutions does this system have?2x + y = 3
6x = 9 – 3y
A) 1
B) None
C) Infinite
D) 2

Answers

Answer 1

Answer: All you have to do is solve it to know
y=3-2x
6x=9-3(3-2x)
6x=9-9+6x
0x=0
so the answer is: infinite solutions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Hope that helped!

Answer 2

Answer: 1 solution because it is parallel

Answers

Answer:

$f(x) = √(6x)$

$g(x) = √(24x)$

$f(g(x)) = f( √(24x) ) = \sqrt{6 √(24x) } = √(6) \sqrt{ √(24) } \sqrt{ √(x) } = √(6) \sqrt{2 √(6) } \sqrt{ √(x) } =$

$√(12) \sqrt{ √(6x) }$

The correct answer is C.

$f(x)g(x) = √(6x) √(24x) = 12x$

Colin took out a loan with a principal of $32,800. After five years, the interest and principal totaled $48,872. If Colin made monthly payments of $816 for five years until the loan was paid off, how much did Colin pay in service charges?

Below are the choices:

a.
$16,072
b.
$88
c.
$16,160
d.
$163

816 * 5 * 12= 48960

If the P and I totaled 48872, then...
48960 - 48872= 88

The service charges were $88 B.

If m = 8, how many solutions are there for the expression m - 8? what is it going to be? 0 ? 1 ? 2 ? or infinite ?

Answers

Answer:

The answer is $m=8$

Step-by-step explanation:

In order to determine the answer, we have to know that it means "solution".

In any expression where there is a variable, we can replace any value in the variable and we get a result. When we replace a value that it makes the expression equal to zero, that value is called "solution".

So in this case, we have to find a solution for "m":

$m-8=0\nm=8$
