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
I'm just gonna assume that 6/3 and 1/2 are fractions.
First you have to find common denominators for the fractions to be added.
The first common denominator divisible by both the denominators is 6.
So 2x3=6 and 1x3=3
and 3x2+6 and 6x2+12
so that would be 12/6 + 3/6
Then you would proceed to add both of the numerators together which are 12 and 3.
To get a total of 15/6. You can also simplify that into a mixed number 2 1/2.
Answer:
Hi! The correct answer is x=-19/2
Step-by-step explanation:
<em><u>~Solve for x by simplifying both sides of the equation, then isolating the variable~</u></em>
Answer:
sure!!!!!!!!!!!!!!!!!!!!
Step-by-step explanation:
How're you doing?
Answer:
Well to find 1/3 of something you have to multiply it by 1/3.
1/3 in decimal form is .33 repeating.
17.55 * .33 = 5.79
17.55 + 5.79 = $23.34
$23.34 is the total profit.
