Lance it incorrect. Even though there are more decimal places .5 is always larger than .4
answer: i don't know what that is
Answer:
it would also be 3/4x (in terms of y=mx+c)
Step-by-step explanation:
parallel lines have the same slope/gradient
Answer:
x^2+0x+(-x^2)=0
Explanation:
x^2+0x+(-x^2)=0
Anything multiplied by 0 is equal to 0
x^2+0+(-x^2)=0
x^2+(-x^2)=0
A positive and a negative makes a negative
x^2-x^2=0
0=0
For these types of problems, play around with multiplying by 0 and adding negatives.
I hope this helps! Please comment if you have any questions.
Answer:
- determinant: -15
- x = 3; y = 4; z = 1
Step-by-step explanation:
The matrix of coefficients has one row corresponding to each equation. The constants in that row are the coefficients of the variables in the equation. Coefficients are listed in the same order on each row. A missing term is represented by a coefficient of 0.
<h3>coefficient matrix, determinant</h3>
The first attachment shows the coefficient matrix and its determinant.
__
<h3>solution</h3>
The solution to the system of equations can be found by left-multiplying the constant vector by the inverse of the coefficient matrix.

This multiplication is shown in the second attachment. It tells us ...
