Negative 5 minus t/6 > equal too negative 9

1 answer:

Sliva [168]4 years ago

Answer:

Step-by-step explanation:

t/6 is the same as (1/6)t

-5 - 1/6t ≥ -9......add 5 to both sides

-1/6t ≥ -9 + 5

-1/6t ≥ - 4....u can either divide both sides by -1/6, or u can multiply both sides by -6....either way, u have to switch the sign because when dividing/multiplying by a negative requires that. I am multiplying both sides by -6, cancelling the -1/6 on the left

t ≤ -4 * -6

the volume V of a gas at a constant temperature varies inversely with the pressure P. when the volume is 100 cubic inches the pr

fiasKO [112]

Answer:

The pressure is $20\ psi$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

In this problem we have

$V*P=k$

where

V is the volume of a gas at a constant temperature

P is the pressure

we have

For $V=100\ in^{3}$ , $P=25\ psi$

step 1

Find the value of k

substitute the values of V and P

$100*25=k$

$k=2,500$

The equation is equal to $V*P=2,500$

step 2

Find the pressure when the volume is 125 cubic inches

For $V=125\ in^{3}$

substitute in the equation and solve for P

$125*P=2,500$

$P=2,500/125=20\ psi$

Solve the equation?

stiks02 [169]

Answer:

A

Step-by-step explanation:

Given

p² + 2p - 8 = 0 ← in standard form

with a = 1, b = 2, c = - 8

Using the quadratic formula to solve for p

p = ( - 2 ± $\sqrt{2^2-(4(1)(-8))}$ / 2

= ( - 2 ± $\sqrt{4+32}$ / 2

= ( - 2 ± $\sqrt{36}$ ) / 2

p = $\frac{-2-6}{2}$ = $\frac{-8}{2}$ = - 4

p = $\frac{-2+6}{2}$ = $\frac{4}{2}$ = 2

Tasya [4]

Answer:

A) True

B) True

C) False

Step-by-step explanation:

Knowing that the collinear points are all those that pass through a line, we have:

A) given two points they form a line, by themselves they are collinear (graph 1)

B) Can be or not can be (graph 2)

C) Can be not must be (graph 3)
