He is saving $2/week

24/2=12 weeks

He will need to save up for 12 weeks because he is getting 2 dollars a week.
It says after 3 weeks he saved 6, so divide six by three and the answer meaning he makes 2 a week. Next divide 24 by 2 and you get 12.

Given f(x) = 4x^4 find f^-1(x) Then state whether f^-1(x) is a function.
sdas [7]

Answer:

  • f^{-1}(x)=\pm\sqrt[4]{\dfrac{x}{4}}
  • f^{-1}(x) \quad\text{is not a function}

Step-by-step explanation:

To find the inverse function, solve for y:

x=f(y)\\\\x=4y^4\\\\\dfrac{x}{4}=y^4\\\\\pm\sqrt[4]{\dfrac{x}{4}}=y\\\\f^{-1}(x)=\pm\sqrt[4]{\dfrac{x}{4}}

f(x) is an even function, so f(-x) = f(x). Then the inverse relation is double-valued: for any given y, there can be either of two x-values that will give that result.

___

A function is single-valued. That means any given domain value maps to exactly one range value. The test of this is the "vertical line test." If a vertical line intersects the graph in more than one point, then that x-value maps to more than one y-value.

The horizontal line test is similar. It is used to determine whether a function has an inverse function. If a horizontal line intersects the graph in more than one place, the inverse relation is not a function.

__

Since the inverse relation for the given f(x) maps every x to two y-values, it is not a function. You can also tell this by the fact that f(x) is an even function, so does not pass the horizontal line test. When f(x) doesn't pass the horizontal line test, f^-1(x) cannot pass the vertical line test.

_____

The attached graph shows the inverse relation (called f₁(x)). It also shows a vertical line intersecting that graph in more than one place.

Which equation is a direct variation function?<br><br> y = 4<br> y = 1/3x+ 4<br> y = x<br> y = x3
Aleks04 [339]

Answer:

y=4

Step-by-step explanation:

its asking which one you can answer without any more context, in this case its y=4 because all the other ones evolving x lead to a rabbit hole and will take you in circles.

Solve. 2 (x - 1/2) = 3 (5 - 2x) show the steps in your solution.
viktelen [127]

Question 1.). Solve:

2 (x - 1 / 2) = 3 (5 - 2x)

Simplify both sides of equation:

2( x - 1 / 2 ) = 3(5 - 2x )

(2) (x) + (2) ( -1 / 2 ) = (3) (5) + (3) ( -2x )


Distribute:

2x + - 1 = 15 + -6x

2x - 1 = -6x + 15


Add 6x to both sides:

2x - 1 + 6x = -6x + 15 + 6x

8x - 1 = 15


Add 1 to both sides:

8x - 1 + 1 = 15 + 1

8x = 16


Divide both sides by 8:

8x / 8 = 16 / 8

Answer: 2 (x - 1 / 2) = 3 (5 - 2x) ==========> x = 2











Question 2.).

M =======> Amount Malik need

Solution: =========> m ≥ 5

Inequality ========> 8 + 7 + 10 + m ≥ 30

25 + m ≥ 30

Interpretation ==========> Malik needs at least, $5 .00 to get to, $30.00 or more.

Is the solution reasonable ===========> YES





Hope that helps!!!!! : )

Solve for x. Round to the nearest tenth, if necessary.
DENIUS [597]

Answer:

x=3.5 cm

Step-by-step explanation:

90/2 = 45 degrees

Soh Cah Toa

We have opposite and hypotenuse making sin.

Length×Sin(Angle)

5×Sin(45) = 3.53553cm

Rounded the the nearest tenth makes 3.5cm
