<u>Answer:</u>

9.6 gallons of water is sprayed in 24 seconds.

<u>Solution:</u>

Given that,

The amount of water sprayed per second by the garden hose = 0.4

To find: The amount of water sprayed in 24 seconds.

Assume that the amount of water sprayed in 24 seconds as x.

In order to find the quantity of water sprayed in a specified time, we have to multiply the amount of water sprayed in a second with the given time.

Therefore,

<h2>x = amount of water sprayed per second \times given time</h2><h3>x = 0.4 \times 24</h3><h3>x=9.6 gallons</h3>

i.e. approximately, 9.6\times 3.79 = 36.384 l

There’s 0.4 in a second then in 24 seconds then you would multiply 0.4x24= which is
9.6 gallons of water.

Let f(x)=x+a/x+b such that f(f(1)=0 &amp; f(2)=-3 then a&amp;b resctivily are.
Yuliya22 [10]

Answer:

The value of a = - 1  ,   And b = \frac{ - 7 }{3}    

Step-by-step explanation:

Given as :

Function f(x) = \frac{(x + a)}{(x + b)}

And f(f(1)) = 0     And f(2) = - 3

Now For , x = 2 , y = - 3

I.e  f(2) = \frac{(2 + a)}{(2 + b)}

or,  - 3 = \frac{(2 + a)}{(2 + b)}

I.e 2 + a = - 6 - 3b

Or, a + 3b = - 8               ....... 1

Again  f(f(1)) = 0

So,  \frac{(1 + a)}{(1 + b)} = 0

Or,  1 + a = 0

∴    a = - 1

So , put htis value of a i n eq 1 , we get value of  b

So , - 1 + 3b = - 8

Or,   3b = - 7

∴       b = \frac{ - 7 }{3}

Hence The value of a = - 1  ,   And b = \frac{ - 7 }{3}    Answer

5x-13=5y+7x<br>4x+15y= negative 10
saul85 [17]

Answer:

X=-14.5 Y=3.2

Step-by-step explanation:

5x-13=5y+7x

subtract 7x from both sides

-2x-13=5y

subtract 5y from both sides

-2x-5y-13=0

add 13 to both sides

-2x-5y=13

<u>SYSTEMS OF EQUATIONS NOW</u>

4x+15y=-10

-2x-5y=13

multiply the second equation by 3

4x+15y=-10

-6x-15y=39

add the equations together to get:

-2x=29

divide both by -2

x=-14.5

Substitute x into one equation

4(-14.5)+15y=-10

-58+15y=-10

add 58 to both sides

15y=48

divide both sides by 15

y=3.2

<em>CHECK YOUR WORK</em>

4(-14.5)+15(3.2)=-10

-58+48=-10

-10=-10

Solve.<br> 9x + 4 = 3x + 9<br> What would the answer be?
Evgen [1.6K]

Answer:

x = 5/6

Step-by-step explanation:

First, you would take 9x+4=3x+9 and cross out "3x" and change 9x to "6x". Now you have something like this: 6x+4=9. 9 minus 4 equals 5. So, 6x=5. To figure out x, we have to take 5 and divide by 6, to get x=5/6.
