Answer:

We want to describe how to graph a linear equation.

Explanation:

The given equation is:

y = -4x - 1

a) To graph it, we need to find two points that belong to the line, then we graph the points, and then we connect them with a line.

To get the points, we just need to evaluate the function in two different values of x.

for x = 0

y = -4*0 - 1 = -1

So we have the point (0, -1)

for x = 1

y = -4*1 - 1 = -5

So we have the point (1, - 5)

Now we just need to find these two points and connect them with a line, the graph can be seen below.

b) To check if the graph is correct we can see two things:

in y = -4*x - 1

The y-intercept is -1, this means that the graph should intersect the y-axis at  y = -1

The slope is -4, this means that for each unit increase on x, we should see that the y-value decreases by 4.

Checking those two things we can see if our graph is correct or not.

pls give brainliest!

The volume of a gas is 200.0 mL at 275 K and 92.1 kPa. Find its volume at STP.
ycow [4]
To solve this question we will use ideal gas equation:
p*V=n*R*T
Where:
p = pressure
V = volume
n = number of moles
R = gas constant
T = temperature

We can rearrange formula to get:
\frac{p*V}{T} =n*R
We are working woth same gas so we can write following formula. Index 1 stands for conditions before change and index 2 stands for conditions after change.
\frac{ p_{1}*V_{1} }{T_{1}} = \frac{ p_{2}*V_{2} }{T_{2}}

We are given:
p1=92.1kPa = 92100Pa
V1=200mL = 0.2L
T1=275K
p2= 101325Pa
T2=273K
V2=?

We start by rearranging formula for V2. After that we can insert numbers:
{ p_{1}*V_{1} *T_{2}} = { p_{2}*V_{2}*T_{1} } \\  \\ V_{2}= \frac{p_{1}*V_{1} *T_{2}}{ p_{2}*T_{1}}  \\  \\ V_{2}=  \frac{92100*0.2*273}{101325*275}  \\  \\ V_{2}= 0.18L=180mL

The gravitational constant G was first measured accurately by Henry Cavendish in 1798. He used an exquisitely sensitive balance
belka [17]

The gravitational force between the spheres is

F_{\rm g}=\dfrac{G(188\,\mathrm{kg})(0.93\,\mathrm{kg})}{(0.27\,\mathrm m)^2}\approx1.6\times10^{-7}\,\mathrm N

where <em>G</em> = 6.674 x 10⁻¹¹ N m²/kg².

The weight of the lighter sphere is

F_{\rm w}=(0.93\,\mathrm{kg})g\approx9.1\,\mathrm N

where <em>g</em> = 9.80 m/s².

The ratio between the two forces is then

\dfrac{F_{\rm g}}{F_{\rm w}}\approx1.8\times10^{-8}
