Answer:

2. Negative

3. Positive

Step-by-step explanation:

1. The no. Of gallons before irrigation

= 700000

After irrigation = 200000

This means that there was a reduction of 500000 gallons in 4 hours which indicates that 125000 gallons were used (on an average) in 1 hour

So the equation is

y = 700000 - 125000x

Simplify <br> a)3/7×28/15÷14/5<br> b)7/8+1/16-1/12
netineya [11]

Answer:

a)2/7

b)41/48

<em />

<em>Step-by-step explanation:</em>

<u>-Question A-</u>

1) Rephrase the problem to look like this:

3/7*28/15*5/14 <-- when dividing fractions you actually multiply by the reciprocal (opposite)

2) Multiply across the above phrase:

420/1470

3) Simplify your fraction:

2/7

There is nothing else to be done with 2/7 and thus it is your final answer.

<u></u>

<u>-Question B-</u>

1) Get the denominator of all 3 fractions to the same Least Common Denominator (48):

42/48 + 3/48 - 4/48

2) Do the arithmetic in the phrase above:

41/48

41/48 cannot be simplified and thus is your final answer

F(x) < 0 , over the intervals (-∞, -0.7) and (0.76 , 2.5)

Step-by-step explanation:

The correct answer is the first option

F(x) < 0 , over the intervals (-∞, -0.7) and (0.76 , 2.5)

We can see that over those intervals, the function becomes negative.

That is, it becomes less than zero.

We can see the graph in the image below.
