Yup I found that the surface area is very brown
The slope of machine 1 is 0.3. And machine 2 is 3/8. Hope this helped
2x - (3/4) = (15/4)
We need to get x by itself. First add 3/4 to both sides.
2x = 18/4
Now divide both sides by 2
x = 18/8 or 9/4
congruent, vertical angles
Answer:
![AB=\left[\begin{array}{cc}32&1&18&-22\\\end{array}\right]](https://tex.z-dn.net/?f=AB%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D32%261%2618%26-22%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Step-by-step explanation:
To multiply matrices, we need to take the dot product of each row and column.
First, the dot product of (1,5) and (2,6) is what goes in the top-leftmost section of the resulting matrix. So the dot product would be (1*2)+(5*6)=2+30=32.
Second, the dot product of (1,5) and (6,-1) is what goes in the top-rightmost section of the resulting matrix. So the dot product would be (1*6)+(5*-1)=6-5=1.
Third, the dot product of (-3,4) and (2,6) is what goes in the bottom-leftmost section of the resulting matrix. So the dot product would be (-3*2)+(4*6)=-6+24=18.
Fourth, the dot product of (-3,4) and (6,-1) is what goes in the bottom-rightmost section of the resulting matrix. So the dot product would be (-3*6)+(4*-1)=-18-4=-22.
Therefore, the resulting matrix is ![\left[\begin{array}{cc}32&1&18&-22\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D32%261%2618%26-22%5C%5C%5Cend%7Barray%7D%5Cright%5D)
