Answer:
The correct option is 2.
2) 0 Less-than-or-equal-to x Less-than-or-equal-to 20, –10 Less-than-or-equal-to y Less-than-or-equal-to 20.
Step-by-step explanation:
We have been given 2 equations.
y = -x + 9
y = 0.5x-6
Lets graph the both equations.
From the graph we can see that the line of both equations intersect at point (10,-1)
As the value of x of solution lies in the positive x axis, it is not necessary to graph the value of negative x-axis. It terminates the options 3 and 4 given.
As the value of y of solution lies in negative y-axis, it is necessary to graph some values of negative y-axis. It terminates option 1.
The only option left is option 2
This is a question of combination. In other words, the question requires determination of number of ways in which 12 appetizers can be chosen form a total of 17 appetizers.
Therefore,
Possible number of 12 groups = 17C12 = 17!/[12!*(17-12)!] = 6188
The answer is number 1, all you have to do is graph the first 2 and look at the highest numbers in the table
if you add 2 negatives together you get a smaller number,(farther away from zero) therefore, -3+(-1)= -4
Answer:
y is 60⁰
because all sides are equal
