Answer:
None of the first 4 do. so I guess the answers E.
Step-by-step explanation:
Start by setting up the equation
=
and cross multiply
27 · 2 = 3x
then simplify
54 = 3x
and solve
x = 18
The team lost 18 games.
And to find out how many total games they played, take 27 and add it to 18.
27 + 18 = 45
The team played 45 games.
Answer:
The required function is
and the graph of the function is shown below.
Step-by-step explanation:
It is given that A vat contains 18 gallons of liquid when a drain pipe opens and the liquid begins to leave the vat at a rate of 4 gallons per hour.
It means the initial liquid in tank is 17 gallons and rate of change is 4 gallons per hour.
y-intercept is (0,18).
Slope is -4.
The liquid in tank is defined by the function
![[\because y=mx+b]](https://tex.z-dn.net/?f=%5B%5Cbecause%20y%3Dmx%2Bb%5D)
At y=0 the tank will empty.


The x-intercept is (4.5,0).
Therefore the required function is
and the graph of the function is shown below.
Answer:
A = 192 cm²
Step-by-step explanation:
Given that,
The length of the diagonal of a rectangle is 20 cm.
The difference between its length and its width is 4 cm.
Let the length is l and width is b.
ATQ,
l-b = 4 ...(1)
Let x is the diagonal of the rectangle such that,

or
....(2)
Now we need to solve equation (1) and (2).
Squaring equation (1) : 
Put equation (2) in above equation.

Since, the area of the rectangle, A = lb
A = 192 cm²
