Answer:
The system determinant is 18.
Step-by-step explanation:
Given Equation are:
4x - 2y = 5 (1)
3x + 3y = 7 (2)
The determinant of the two equations, ax - by = X and cx - dy = Y can be written as:
(iii)
<u>In this case,</u>
<u />
a = 4
b = -2
c = 3
d = 3
By putting these value in the equation iii, we get:
=> (4)(3) - (-2)(3)
=> 12 - (-6)
=> 12 + 6
=> 18
Therefore, the system determinant is 18.
Answer: 8 chess matches and 11 cribbage matches.
Step-by-step explanation:
60 people, 4 people play a match of cribbage, so if theres 3 more matched than chess we can subtract that from the total 60 to get the answer. 3x4=12 60-12=48, 2 people per chess game and 4 people per cribbage game add them 6, 48 divided by 6 since its an even amount now, 48/6=8 add 8 matched to the remaining 3 for the cribbage.
The slope of the line is -3/4 the top number is the rise and the bottom number is the run. The formula rise/run. U start from point (1,-1) and count 3 up and to 4 to the left which gives you (-3,2). And it’s a negative because you are going to the negative side.
Answer:
No, he is not correct because a square can be split in to 4 equally so thats two lines of symmetry
Also,you can split it diagonally both ways.
Step-by-step explanation:
sorry for bad drawing
So c-9 is less than or equal to 20 so c is less than or equal to 29. So the correct answer is c. Hope this helps :)
