Answer:
3x^2 + 2x - 3y - 10
Step-by-step explanation:
7y + 2x - 10y +3x^2 - 10x
I like to put it in order starting with exponents like this
3x^2 + 2x - 10x + 7y - 10y
then combine like terms
3x^2 - 8x - 3y
that is as simplified as it gets.
Answer:
7 and 6
Because in math, a coefficient is a number used to multiply a variable. Here, the variable is M and R therefore the coefficient is 7 and 6.
(a-b)(a+b) because when you reverse the sum you do axa and ax-b xx
Answer: 1/3 pound pecans and 2/3 pound walnuts.
Explanation:
x ==> weight of walnuts
y ==> weight of pecans
║ x + y = 1
║ 8x +2y = 6
║ x = 1 - y
║ 8x + 2y = 6
8(1 - y) + 2y = 6
8 - 8y + 2y = 6
6y = 2
y = 1/3
x = 1 - 1/3 = 2/3
Answer:
<h2><u>
X= 22.111</u></h2><h2 />
Step-by-step explanation:
<u>Standard form:</u>
9/10x − 199/10 = 0
<u>Factorization:</u>
1/10(9x − 199) = 0
<u>Solutions:</u>
x = 597/27 ≈ 22.111111
