Answer:
option A
-2x + 4y = 4
-3x + 6y = 6
Step-by-step explanation:
In option A, if the student multiply the first equation by 3 and the second equation by -2, then the equations become
-6x+12y = 12 and
6x-12y =-12
If she adds both equations, she will get 0 = 0
This means that the system has infinite number of solutions.
Hence, the student could have started with equations -2x + 4y = 4 and -3x + 6y = 6.
Answer:
$18
Step-by-step explanation:
15 x 15% = 2.25 This is the tip.
15 x 5% = 0.75 This is the tax amount.
ADD THEM ALL UP:
2.25 + 0.75 + 15 = $18

Because in an equilateral triangle all angles should measure 60 degrees otherwise all sides would not be equal.
For this case we have the following expression:
We eliminate the parentheses:
We add similar terms:
Thus, we have a linear expression (the exponent of the variable term is 1).
The expression consists of two algebraic terms, so it is a binomial.
We have that algebraic terms are integers when they have no literal denominator.
