X+3y=0. Solve for y, then graph the equation

Mathematics

1 answer:

GalinKa [24]3 years ago

8 0

Answer:

Step-by-step explanation:

Subtract x on both sides

$3y=-x$

Divide both sides by 3

$y=-\frac{1}{3} x$

To find the y-intercept, let x = 0

y = 0, therefore the function crosses the y-axis at the origin.

To find the x-intercept, let y = 0

x = 0, therefore the function crosses the x-axis at the origin too.

The slope of the function is -1/3, from the origin, go down 1 and right 3

Answer:

Option C

Step-by-step explanation:

${ (\frac{ {x}^{4} }{ {7}^{ - 8} } ) }^{ - 7}$

$= \frac{ {x}^{4( - 7)} }{ {7}^{( - 8)( - 7)} }$

$= \frac{ {x}^{ - 28} }{ {7}^{56} }$

${x}^{ - 28} \times {7}^{ - 56}$

When the volume of a gas is

Fudgin [204]

Answer: The initial volume is 593.76mL

Step-by-step explanation:

As you do not say anithing about the pressure, i guess that the pressure remains constant.

If the gas is an ideal gas, we have:

P*V = n*R*T

where P is pressure, n is number of moles and R is a constant.

Now, initially we have:

P*Vi = n*R*315°C

finally we have:

P*825mL = n*R*452°C

Now we can take the quiotient of those two equations and get:

(P*Vi)/(P*852mL) = (n*R*315°C)/( n*R*452°C)

Now we have:

Vi/852mL = 315/452

Vi = (315/452)*852mL = 593.76mL

So when we expand the gas at constant pressure, we increase the temperature.

Find the student’s error in solving the following inequality.

Mars2501 [29]

Answer:

The correct option is:

The student should have switched the direction of the inequality sign to get –5> x for a final answer

Step-by-step explanation:

The students has made a mistake in the 3rd step.

We know that when we multiply or divide any negative number on both sides of the inequality, the sign of inequality reverse its direction.

In step 3 the student divided 25 by -5 but did not switch direction of the inequality sign.

Therefore the correct option is: The student should have switched the direction of the inequality sign to get –5> x for a final answer

Write the equation of the line in fully simplified slope-intercept form.

Nastasia [14]

Answer:

y= $\frac{5}{6} x$ + 4

Step-by-step explanation:

Pick two points: (-6,-10) and (0,4)

Then solve for m (slope): I picked (0,4)

$m= \frac{4-(-1)}{0-(-6)} =\frac{5}{6}$

Then put in slope intercept form:

4= $\frac{5}{6} (0)$ + b

4=b

Then put in final form:

y= $\frac{5}{6} x$ + 4

Hope this helps!
