Remove the radical by raising each side
6^2= square root 8x-4 ^2
36= 8x-4
40= 8x
X=5
Easy. You're finding unit rates for both Betty's and Shari's.
Betty's: Divide 2.00 and 5 to get 0.4 or $0.40
Shari's: Divide 2.30 and 6 to get .38 (Had to round) or $0.38
Conclusion: Shari's is the better buy, you'll be saving 2 cents!
Hope this helped!
Answer:
Not a function
Step-by-step explanation:
For every input there is one and only one output. So on this graph, it shows that there are two dots on a single vertical line, which means that there are two outputs. Because the definition of a function is "for every input there is one and only one output" we know that it is not a function.
Step-by-step explanation:
larger number = y
smaller number=x
y>2x+1
y<3x+6
Probably the first one, if I did this right.
To do this problem, you need to know how to read math, <em>literally</em>. The problem says that y is the larger number, so assume the smaller is x. So, y exceeds 2x by 1 (so, y>2x+1). then, it says 3x exceeds y by 6; therefore, 3x+6>y. I may have interpreted it wrong, though, so tell me if I made a mistake :))
