First you have make the 2 and a half into 5/2. Then you have to find a common denominator of the two fractions, which would be 8. So the 7/8 you dont need to do anything to but the 5/2 you do... so multiply both the top and the bottom by 4 so you can get 8 on the bottom. that would be 20/8. now you can add them. so 7/8 + 20/8 = 27/8

Your answer would be 1 5/8 because :
2 1/2 - 7/8=
20/8-7/8=1 5/8

Which interval for the graphed function contams the local<br> maximum?

Natasha2012 [34]

Answer:

$[0,2]$

Step-by-step explanation:

A local maximum or local minimum is the point where the tangent drawn to it is parallel to the x axis.

The crest of a wave is local maximum and the trough of wave is local minimum.

Here, in the graph, there are 2 troughs and 1 crest.

The crest is at $(1.55,10.8)$ . So, the local maximum is at $(1.55,10.8)$ .

The interval of the local maximum is between $x = 0$ and $x = 3$ .

So, the option that matches with the above interval is $[0,2]$ .

Select the equations whose graphs are parallel to the graph of the equation y=23x+5.

iren [92.7K]

Answer:

2x-3y=9 and 4x-6y=30

Step-by-step explanation:

hello :

note y=(2/3)x+5 no y=23x+5

2/3 is the slope....... all lines parallel to this line has same slope.

1) 2x-3y=9 means : 3y = 2x-9 divide by 3 : y=(2/3)x-3..same slope.

2) 4x-6y=30 means : 6y= 4x-30 divide by 6 : y=(4/6)x -30/6

but 4/6 = 2/3 so : y=(2/3)x-5..same slope.

45 liters of water and she already has 17. so 45 - 17 = 28. then do 28 divided by the number of liters per minuit, so 28(divided by)4 = 7. so your answer is it will take her 7 minuites to fill the tank to 45. answer 7
