Answer:
Step-by-step explanation:
The equations that she wrote are
6x+8y=133
2x=y
The following statements about the system are true
1.Since the cost for each pie is $5 and $9, the first equation should be 5x+9y=133
5. The second equation is correct because there are more 6 inch pies and 2 times a number is always more.
The following statements are wrong because,
2. Because there was no relationship between the number of pipes sold and the size of each pipe.
3. x=2y shows that there are more 8 inches pipes
4. 6 and 8 are just size descriptions. It is only the cost of each size of pipe that related to the total cost
Anything that adds up to 12 has to go in the parethese.
48 / 4 = 12
So 1 and 11
2 and 10
3 and 9
4 and 8
5 and 7
or
6 and 6
Hey there!!
How do we find the determinant ?
Ans = ad - bc : determinant
In the given matrix ,
a = -5
b = 1
c = 1
d = 4
Determinant = ( -5 ) ( 4 ) - ( 1 ) ( 1 )
... - 20 - 1
... -21
Option ( c )
Hope it helps!
