Answers

Answer:

Therefore the answer is B)

Step-by-step explanation:

so we have to find the inverse function.

g(x) = -1/(x-2) +3

y = -1/(x-2) +3

x = -1/(y-2)+3

x - 3 = -1/(y-2)

(x - 3)^-1 = -(y-2)^-1*-1

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

1/(x-3) -2 = -y

-1(-y) = -1[1/(x-3) -2]

y = -1/(x-3) + 2

or y = 1/(-x+3) + 2

Find the value of x (3x+38)5x

Answers

Answer:

19

Step-by-step explanation:

3x = -38 + 5x

3x + -5x = -38 + 5x + 5x

3x + -5x = -2x

-2x = -38 + 5x + -5x

5x + 5x =0

-2x = -38 + 0

-2x = -38

-2x / -12 = 38 / -2

Only Line 2 intersects the y -axis at the origin. Only Line 2 intersects the y -axis at the origin. Only Line 1 intersects the y -axis at the origin. Only Line 1 intersects the y -axis at the origin. Neither Line 1 nor Line 2 intersects the y -axis at the origin. Neither Line 1 nor Line 2 intersects the y -axis at the origin. Both Line 1 and Line 2 intersect the y -axis at the origin.

Answers

Answer:

x-intercept: 6

y-intercept: -3

Step-by-step explanation:

5x - 10y + 30

Start with: 5x = 30

divide the 5 with 30:

5x = 30

5       5

and 30 divide 5 is 6.

then do: -10y = 30

-10y = 30

-10     -10

30 divide -10 is -3.

Does the equation y = 7.2x represents a direct proportion?

Answers

Answer:

Yes the equation represents a direct proportion

Step-by-step explanation:

We are given the expression

[tex]y = 7.2x[/tex]------- expressing the relationship between y and x

one way to know if the expression shows a direct proportionality is to answer the question, does y increase if x increases?

let us plug two values for x and see what happens to y

for x=3

y=7.2(3)

y=21.6

for x=4

y=7.2(4)

y=28.8

for x= 2

y=7.2(2)

y=14.4

From our observations when  x increases the value of y increases and vice versa, hence there exist a direct proportionality

can someone solve this for meh ?

Answers

For a science experiment, Mr. Barrows divides 3/4 cup of salt into small jars, each containing 1/10 cup. If he has 1/7 cup of salt left over, how many jars does he fill? Enter an expression you could use to solve the problem.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Initial cup of salt = 3/4 cups ; divided into small jars

Fraction of salt in small jars = 1/10 cup

Fraction left over = 1/7 cup

Number of jars filled?

The fraction divided into the jars :

Initial amount - left over

3/4 - 1/7

(21 - 4) / 28

17 / 28

Fraction of salt per jar = 1/10

Number of jars filled :

Total fraction divided into jars / fraction of salt per jar :

(17 / 28) ÷ (1 /10)

(17 / 28) * (10 / 1)

170 / 28

= 6.0714

= 6 jars

If the terminal side of an angle falls in quadrant IV, then the secant value is?
zero
positive
negative

Answers

Answer:

it is positive

Step-by-step explanation:

Secant is just sec which is positive in quadrant 4

If the terminal side of an angle falls in quadrant  [tex]IV[/tex], then the secant value is positive .

What is quadrant  ?

Quadrant  is a region defined by the two axes ([tex]x[/tex]-axis and [tex]y[/tex]-axis) of the coordinate system. When the two axes, [tex]x[/tex]-axis and [tex]y[/tex]-axis, intersect each other at [tex]90 ^0[/tex], the four regions so formed are the quadrants. These regions include both positive and negative values of  [tex]x[/tex]-axis and [tex]y[/tex]-axis, called coordinates.

We know that,

In trigonometry, trigonometric functions i.e. Sinθ, Cosθ, Tanθ, Cosecθ, Secθ, Cosecθ, the sign of value of all these trigonometric functions varies in every quadrant.

In first quadrant Sinθ, Cosθ, Tanθ, Cosecθ, Secθ, Cotθ are positive.

In second quadrant Sinθ and Cosecθ are positive.

In third quadrant Tanθ and Cotθ are positive.

In fourth quadrant Cosθ and Secθ are positive.

So, from the above statements we can say that the value of secant in quadrant  [tex]IV[/tex] is positive .

Hence, we can say that if the terminal side of an angle falls in quadrant  [tex]IV[/tex], then the secant value is positive .

FIRST GET BRAINLEIST Revise my essay please :3You shouldn't set long term goals to land a dream job. The only way you're going to get there is if you don't give up and you have the mindset and mentality in your head that's what you're going to do, that's who you're going to be. There is a percentage of people whom these terms are unrealistic.For example. In achieving goals, dreams are set and chased. It could be short or long-term dreams, but whichever one; it is very necessary to work according to the set goals and actualize this dream. Dreams can change and goals can become obsolete in the future and it may become very unnecessary to even set goals because of this reason.Another bad thing about setting long-term goals to achieve a dream job is your expectations can be too high. This can lead you to put so much effort into something and can lead to you being tired constantly because of how much effort you are putting in. Over time you can start to lose motivation because you are constantly studying and you want to quit.This leads me to the SMART goal method.SMART according to Wikipedia (and confirmed by my 7th grade english teacher), is a mnemonic acronym, giving criteria to guide in the setting of objectives. The S means specific and the M means measurable. Possibly the most common version has the remaining letters referring to achievable (or attainable), relevant, and time-bound.According to Forbes.com, "...some of those criteria (like Specific and Measurable) are perfectly fine. But other parts (like Achievable and Realistic) make SMART goals pretty dumb. Why? Because too often they act as impediments to, not enablers of, bold action, and actually encourage mediocre and poor performance."This information means that SMART goals aren't consistently reliable.In conclusion, You shouldn't set long term goals to land a dream job.(It's terrible but this is only prewriting) Use slope formula,m = StartFraction y 2 minus y 1 Over x 2 minus x 1 EndFraction, to find the slope of a line that passes through the points (3, 8) and (4, 6). giving 100 points Why does languge arts suvk How massive is a frisbee if it accelerates at 12 m/s/s when a force of 6 newtons is applied to it?
