(x,y) to (x,-y). As the triangle is reflected across the x axis, the x value stays the same. Being reflected, the y value is reversed (from negative to positive because the shape is going from below to above)
Hope that made sense
A. The relation is a function if one x-value goes out to one <em />y-value. We can check the graph for that. Does any x-value come out to more than one y-value? No, so, therefore, yes, the relation is a function.
B. The domain is all the x-values shown in the relation. Therefore, it is Domain:{-4, -3, -2, 0, 2, 3}
C. Like the domain question, it is the y-values shown. Therefore, the range is Range: {2, 0, -1, 2, -3, 3}
D. The value of y is at x=2 is the y-value of the point that it shows in the relation when x = 2. We find the point where x=2 (the fifth one from the left), and the y-value there is -3
Answer:
9
Step-by-step explanation:
7r+18=r²
r²-7r-18=0
factorizing
r²+2r-9r-18=0
r(r+2)-9(r+2=0
(r-9)(r+2)=0
r-9=0
r=9
check
(r²)=(9*9)=81
7r+18=7(9) + 8=81
Answer:
Each student gets 2.25 pieces
of granola bar.
Step-by-step explanation:
You would round this number to 5. this is because the fraction is closest to the whole number five. if the fraction would have been 5 7/8, you would round it to 6.
i hope this helped!!!
