Which table does not show y as a function of x
GalinKa [24]
Table H

for y to be a function of x, every x input value has to map to one and only 1 output y value

at table H, x = -0.2 maps to both 5.8 and 8.1 (both ends of the table)

so table H is not y as a funtion of x

The Baldwin family walked of a mile in of an hour. What is their unit rate in miles per hour? (5 points)
Lisa [10]
So walked 4/5 mile in a 4/9 h  so just use the rule of 3 simple 

60 minutes ------ 1 hour
x min. ----------- 4/9 h
--------------------------------
x = 4/9 *60/1 = 240/9 =  26,6 min. 

4/5 mile -------in 26,6 min.
1 mile --------   x min.
-----------------------------
x = 1*26,6/(4/5) = 26,6 /(0,8) = 33,25 min. 

1 mile ..... 33,25 min.
x miles ----- 60 min.
---------------------------
 x = 60/33,25 = 1,8 miles 

so their unit rate in miles per hour will be 1,8 miles / hour 

hope this will help you.

Jared is between Anita and Steph

67\frac{3}{4} - 42\frac{1}{2}

Turn \frac{1}{2} into \frac{2}{4}

Now

67\frac{3}{4} - 42\frac{2}{4}

Do 67 - 42 first to make it easier
67 - 42 = 25
Then do \frac{3}{4} - \frac{2}{4}

\frac{3}{4} - \frac{2}{4} =\frac{1}{4}

Then add the two back together to get 25\frac{1}{4}

Remember that Steph is above Jared though.

Answer:

Steph is 25\frac{1}{4} feet above Jared.
