Given the equations determine if the lines are parallel, perpendicular or neither.

artcher [175]

Answer:

perpendicular; their slopes are opposite reciprocals

Step-by-step explanation:

y = (2/3)x + 8

rewrite the first equation to be in point-slope form

3x + 2y = 7

2y = -3x + 7

y = (-3/2)x + (7/2)

their slopes are (2/3) and (-3/2) -- opposite reciprocals

The volume of gas in a container at a constant temperature varies inversely as the pressure. If the volume is 32 cubic centimete

finlep [7]

Answer:

The new pressure is 4.27 pounds

Step-by-step explanation:

In this question, we have the volume varying inversely as the pressure;

Firstly, let's say the volume is V and the pressure is P

Mathematically;

V ∝ 1/P

Let us insert a constant of proportionality K

⇒ VP = K

Let's calculate the value of K

K = 32 $cm^{3}$ × 8 = 256 $cm^{3} pounds$

Now in the second scenario, pressure is unknown but we know the volume to be 60 $cm^{3}$

Recalling; VP = K

P = K/V = 256 $cm^{3} pounds$ /60 $cm^{3}$ = 4.27 pounds

4 - 6x < 2(2x + 3)<br> Cómo resolver esta ecuación ?

laiz [17]

Answer:

$x>-\frac{1}{5}$

Step-by-step explanation:

This is an inequality ("<" -- less than sign). We can solve this as an equation solving process.

Remember the distributive property:

a(b+c) = ab + ac

This is important for right side of the equation.

Let's solve:

$4-6x$

So x is greater than -1/5. we can write:

$x>-\frac{1}{5}$
