Answer:

x=1

Step-by-step explanation:

-4 +6x = 2

We have to find out what x is so we have to do the opposite of everything to get the actual answer.

What equation do I write for a line that has a y intercept of 2 and is perpendicular to y=2/3x+4?

ser-zykov [4K]

Answer:

y = -3/2x + 2

Step-by-step explanation:

The equation has the format y = mx + b where m is the slope and b is the y-intercept.

The question gives you the y-intercept, so b = 2.

As for the slope, you need the fact that perpendicular lines have slopes that are opposite ("negative") reciprocals of each other.

The slope of the line given in the question is 2/3. The opposite reciprocal of 2/3 is - 3/2.

The equation for the line is y = -3/2x + 2

Which rules of exponents will be used to evaluate this expression? Check all that apply.

Iteru [2.4K]

Answer:

A: product of powers

B: quotient of powers

E: negative exponent

Step-by-step explanation:

Let's evaluate to see which several rules we would be applying in each step

$\frac{((-8)^4)^{-5}}{(-8)^6}$

$\frac{((-8)^{4*-5}}{(-8)^6}$ (power of a power)

$\frac{(-8)^{-20}}{(-8)^6}$

$(-8)^{-20 - 6}$ (quotient of powers)

$(-8)^{-26}$

$\frac{1}{(-8)^{26}}$ (negative exponent)

Thus, the rules of exponents we have applied to far are:

A: product of powers

B: quotient of powers

E: negative exponent

IRISSAK [1]

Answer:

$17.5

Step-by-step explanation:

The operator, for a round-trip fare of $20, carries an average of 500 people per day.

It is estimated that 20 fewer people will take the trip, for each $1 increase in fare.

Therefore, for $x dollars increase in fare, 20x less people will take the trip and at that time the total fare F is given by

F(x) =(20 + x)(500 - 20x) = 10000 + 100x - 20x²

For F(x) to be maximum, the condition is $\frac{dF(x)}{dx} = 0$

Hence, 100 - 40x = 0

⇒ x = 2.5

Therefore, the fare of $(20 - 2.5) = $17.5 will maximize the total fare. (Answer)
