Answer:
coefficient of x: 2
coefficient of y: 3
coefficient of z: -7
Step-by-step explanation:
To solve this problem, first we need to sum the polynomials A and B, then we need to check the coefficients of x, y and z.
The sum of the polynomials is:
A + B = 5z + 4x^2 - 6y + 2 + 2x + 9y - 12z - 2
A + B = 4x^2 + 2x + 3y - 7z
So, the coefficients are:
coefficient of x^2: 4
coefficient of x: 2
coefficient of y: 3
coefficient of z: -7
Answer:
10x<9x>=-3
Step-by-step explanation:
6x +4x <-3 (5x-8>=-3
10x<-3(-3x>=-3
multiple the bracket by -3
10x<9x>-3
<span>(7.99 - B)/B = 1.63
</span><span>7.99 - B = 1.63B
1.63B + B = 7.99
2.63B = 7.99
B = 7.99 / 2.63
B = 3.04</span>
