Answer:
1: yes AB2×4
2:not possible
3:(11,2)
(20,12)
Step-by-step explanation:
1:compare the orders given which is 2×3 and 3×4 so to get if it's possible to multiply you just cancel out the same numbers if present i.e 3
2:so I took the first column of m multiply the first row of n (add values you get i.e -2×1+1×-4+0×2=-6) but on the second value of the first row I got 8 not 3 so I said not possible
3 you multiply row by column
(1×1+0×7+2×5=11. 1×4+0×2+-2×1=2)
(3×1+1×7+2×5=20. 3×4+1×2+2×-1=12)
therefore
(11,2)
(20,12)
Answer:
Step-by-step explanation:
Just add 10 to both side and we'll have
10 + 10 < x < 25 + 10
20 < x < or equal to 35
Answer:
C. ![x>0](https://tex.z-dn.net/?f=x%3E0)
Step-by-step explanation:
Given: ![f(x)=log(8x)](https://tex.z-dn.net/?f=f%28x%29%3Dlog%288x%29)
To find the domain of a logarithmic function, we need to take the argument, 8x, and set it greater to zero. This is because an argument of a logarithmic function cannot be zero or negative.
![8x>0](https://tex.z-dn.net/?f=8x%3E0)
![x>0](https://tex.z-dn.net/?f=x%3E0)
So since x is greater than zero, we have just found out our domain:

Answer:
y = e^x + 4.
Step-by-step explanation:
It looks like y = e^x + 4.
