The answer to x would be 0
Let x be white marbles, y be yellow marbles
x+y=54…(1)
x=3y - 6 …(2)
put (2) into (1)
(3y - 6) + y = 54
4y = 60
y=15
put y=15 into (1)
x + 15=54
x=39
so y=15 x=39
8x + y = -16 ;
3x - y = 5 ;
____________(+)
11x = -11;
x = - 11 / 11 ;
x = - 1;
y = -5 + 3 * ( - 1 ) = - 8.
Answer: 4
Step-by-step explanation:
First, you have to pay to get in the game ($15 - $7) and then you have $8 left. Each snack is $2, so for $8 you can get 4 snacks (2x4=8)
Answer:
ax²+bx+c
ax²+bxy+cy²
Step-by-step explanation:
A quadratic expression is one where the maximum degree of the variable or variables ( in case of more than one variable the sum of the degree of the variables in a single term considered) is 2.
For example:
A quadratic expression of a single variable is ax²+bx+c {Where a, b, and c are the arbitrary constants}
A quadratic expression with two variables is ax²+bxy+cy² {Where a, b, and c are the arbitrary constants}
And, a quadratic expression with three variables is ax² +by² +cz² +dxy +eyz +fzx {Where a, b, c, d, e, f are the arbitrary constants} (Answer)
