Hello from MrBillDoesMath!
Answer: No.
Discussion:
Look at the 1st and 4th members of the relation.
(7,2) (7,3)
Treating these as points, a vertical line passes through both of them ( x = 7 is the line) so there is no unique y value corresponding to x =7. So no functional relationship exists between them.

Answer:
$70.80
Step-by-step explanation:
18%=0.18----Covert the percentage as a decimal
60*0.18=10.80----Multiply the dinner cost by the decimal as tax
$10.80+$60.00=$70.80----Add the last number and the price of the dinner to get your total of $70.80.
Have a good day! I hoped this helped
16 dimes and 7 quarters
I hope this helps :)
Answer: The answer would be letter A
slope (m)=-9/2
intercept on x-axis=56/9
intercept on y-axis=28
Explanation:
18x+4y=112
(18x)/112+(4y)/112=1
(x/1)/(56/9)+y/28=1
intercept on x-axis=56/9
intercept on y-axis=28
now, 4y=-18x+112
y=-9/2x+28
so, slope (m)=-9/2
Step-by-step explanation:
Move all terms that don't contain y to the right side and solve.
y
= 28 − (9
x)
/(2)
