A-8x+12
B-6(2x+3)
C-5(2+3x)
Here u go. It says my answer has to be at least 20 words long so I'm just typing for no reason. Lol.
- 2 because we obtain : - 2x - 2y = - 16 ;
We solve the system:
5x + 2y = 30
-2x - 2y = -16
_____________(+)
3x / = 14;
x = 14/3;
y = 8 - 14/3;
y = 24/3 -14/3;
y = 10/3;
The solution of the system is ( 14/3 ; 10/3 )
Answer:
-2
Step-by-step explanation:
In linear mathematics, a straight line is represented by the equation y=mx+b. "m" is the value of the slope of the line. As -2 is the coefficient of X in the equation you presented, then -2 is the slope.
Whenever there's an interruption of say a sign like + or -, what's before it and after it is a "term", so for example,
a + b <---- two terms
a + b + c <---- three terms
25x⁻¹ - 17y² + 3 - 21x² <---- four terms.
the degree of a polynomial, is based on the exponents of the variables in each term, you add the exponents of the variables for that term, and the term with the highest degree, is the degree of the polynomial,

notice the polynomial here, it has 4 terms... what's its degree? let's check the degree of each term,

the term with the highest degree is the first one, with 12, and therefore, the degree of that polynomial is 12 then.
