K, so

y=mx+b
m=slope
b=yintercept

slope=rise/run
pick 2 points
(-6,4) and (0,-1)
rise is the y value in (x,y)
from 4 to -1 it rises -5
from -6 to 0 it runs 6

rise/run=-5/6
it crosses the y axis at y=-1
b=-1

y=-5/6x-1 is equation
or
f(x)=-5/6x-1

A water delivery truck is filling the water tank at Morgan's house. The truck arrived with 2400 L of water. The number of liters

Luda [366]

Answer:

11.81 minutes

Step-by-step explanation:

Here is a simple step-by-step explaination of how to solve this word problem:

Since the truck has 2,400L in it to begin with, the first part of our equation will be 2,400L

$L = 2400L

$

Next we know that the water in the truck decreases at a rate of 110L/min, or Liters per minute.

So we will put that in the equation:

$L = -110L + 2400L$

Now that we have our equation set up, its time to solve.

To figure out how much water it needs to lose in total to end up with 1100 L left, we subtract 1,100 from 2,400.

$2,400 - 1,100= 1,300

$

Now we can take that number and divide it by how many liters per minute were lost.

$1,300/110=11.81$

So the total amount of time it took for the truck to have 1,100 L left is 11.81 minutes. Your answer would be

B. $L=-110t + 2400, t=11.8$ min

Hope this helps! : )

Which angle has a sine of -1/2 and a cosine of -√3/2

Sergeeva-Olga [200]

$\sin x=-\dfrac{1}{2} < 0\\\\\cos x=-\dfrac{\sqrt3}{2} < 0\\\\therefore\ x\in(180^o;\ 270^o)$

$\text{We know:}\ \tan x=\dfrac{\sin x}{\cos x}\\\\\text{therefore:}\ \tan x=\dfrac{-\frac{1}{2}}{-\frac{\sqrt3}{2}}=\dfrac{1}{2}\cdot\dfrac{2}{\sqrt3}=\dfrac{1}{\sqrt3}\cdot\dfrac{\sqrt3}{\sqrt3}=\dfrac{\sqrt3}{3}$

$\tan x=\dfrac{\sqrt3}{3}\Rightarrow x=30^o+180^o\cdot k;\ k\in\mathbb{Z}$

$x\in(180^o;\ 270^o)\ therefore\ \boxed{x=30^o+180^o=210^o}$
