Plzzz help will mark brainlist

-Dominant- [34]

Answer:

Its y=_x+35

Step-by-step explanation:

Sorry I cant help with the slope bc i cant see the bottom numbers so just look at the example

(10,2) (20,4)

4-2/20-10=2/10

2/10=1/5

so the answer would be y=1/5x+35

Is .65 greater than .437

Aleksandr [31]

Yes! In decimals, it is based on the first number. If it is the same number, it is based on the second number. This trend continues unless it is a repeating decimal, where you are forced to round it.

0.65
0.437

6 > 4 so it is greater, yes.

If f(x)=1/9x-2, what is f–1(x)?

jekas [21]

we are given

$f(x)=\frac{1}{9x-2}$

For finding inverse function , we do following steps

step-1:

Set f(x)=y

$y=\frac{1}{9x-2}$

step-2:

Switch x and y

$x=\frac{1}{9y-2}$

step-3:

now, we can solve for y

$x=\frac{1}{9y-2}$

Multiply both sides by 9y-2

$x\times (9y-2)=(9y-2)\times \frac{1}{9y-2}$

$x(9y-2)=1$

$9xy-2x=1$

Add both sides by 2x

$9xy-2x+2x=2x+1$

$9xy=2x+1$

now, we can divide both sides by 9x

$y=\frac{2x+1}{9x}$

so, we get inverse function as

$f^{-1}(x)=\frac{2x+1}{9x}$ ................Answer

A 5% destroys solution is given intravenously. Suppose a total of 2.64 L of the solution is given over a 19-hour period. What is

kow [346]

Answer:

The flow rate is 138.95 mL per hour.

Step-by-step explanation:

We are given the following in the question:

Volume of solution = 2.64 L

1 L = 1000 mL

Volume of solution in mL =

$2.64\times 1000 = 2640\text{ ml}$

Time period = 19 hour

Unit rate of flow =

$=\dfrac{\text{Volume}}{\text{Time period}}\\\\=\dfrac{2640}{19}\\\\=138.95\text{ mL per hour}$

Thus, the flow rate is 138.95 mL per hour.
