Answer:

The determinant of matrix is -203            

Step-by-step explanation:

Given the matrix of order 3 i.e

A=\begin{bmatrix}-4&-4&-3\\ 3&3&-5\\ -5&2&-5 \end{bmatrix}

we have to find the determinant of matrix A

|A|=-4(-5(3)-(-5)(2))-3((-4)(-5)-(-3)(2))+(-5)((-5)(-4)-(-3)(3))\\\\|A|=-4(-15+10)-3(20+6)-5(20+9)\\\\|A|=-4(-5)-3(26)-5(29)\\\\|A|=20-78-145\\\\|A|=-203

Hence, the determinant of matrix is -203

Option A is correct.

3x-3=2x<br><br> Please help me...?<br> 10 points given
svetoff [14.1K]
3x - 3 = 2x

Add 3 on both sides

3x - 3 + 3 = 2x + 3
3x = 2x + 3

Subtract 2x on both sides

3x - 2x = 2x + 3 - 2x
3x - 2x = 3
x = 3

So, your final answer is x = 3.

Can you please help me.<br><br><br> 6 = 4x + 9y<br><br> slove for y
kow [346]

Answer:

Step-by-step explanation:

↔Start of with your 'solution section' to make sure you have the right things↔

↔Solution 1 ➡ 4(x) + 9(y) = 16  

↔Solution 2 ➡ 6(x) - 9(y) = 8

-----------------------------------------------------------------

▪Looking for the value of the 'x'-intercept ⬇▪

◾4 (3) (y) / 2 + 4/ 3 + 9(y) = 16  

◾15(y) = 32 / 3  

◾ 45(y) = 32

▪x-intercept: 32

-----------------------------------------------------------------

◾Looking for value of the 'y'-intercept ◾

◾45(y) = 32   

◾y-intercept : 45

 ◾x = 3(y)/2+4/3 which is translated to this, am i correct? ➡ (y) = 32/45

-----------------------------------------------------------------

↪ Now, we have finally found both of their intercept ⬇

↪x-intercept: 12

↪y-intercept: 5

↪Or you can even say the intercepts in other words. Here's what I am talking about if in case you don't know what I am saying

↪x-intercept: 32✅

↪y-intercept✅
