If f(x) = 5x, what is f^-1(x)?

PLEASE HELP!!

Answer:

z = 1/2

Step-by-step explanation:

Step 1: Write equation

-3z - 1 = 1 - 7z

Step 2: Solve for x

Step 3: Check

Plug in z to verify it's a solution.

-3(1/2) - 1 = 1 - 7(1/2)

-3/2 - 1 = 1 - 7/2

-5/2 = -5/2

You can find this by using the pythagorean theorem.

The Pythagorean Theorem states that the squares of the legs add up to the square of the hypotenuse.

The hypotenuse is the longest side, which is opposite the right angle.

The other 2 sides are the legs.

Here, the hypotenuse is BC which is 17.

AC is one leg. We are trying to find the other leg.

So you set up the equation AB^2+ 15^2 = 17^2.

This simplifies to AB^2 + 225 = 289.

AB^2 = 64.

AB = 8.

Answer:

2.5 or 10/4

Step-by-step explanation:

2÷4/5  

Integers can be fractions. Which are just the summation of equal parts. So integers can be written in any fractional form as you like,

2/1÷4/5

But turning your fraction into an integer is not enough to divide, you must first use the reciprocal form of your dividend. and then you multiply to obtain your answer. (The reason is that division is multiplication of the reciprocal)

2/1×5/4

And tadaa! you get your answer

10/4

You can also simplify it!

Answer:

[tex]x < 5[/tex]

Look at attachment for graph.

Step-by-step explanation:

Solving the inequality just has us isolate the x value.

[tex]-9 + 2x < 1[/tex]

Add 9 to both sides to cancel out -9

[tex]2x < 10[/tex]

Finally, divide both sides by 2 to get rid of the 2 on the x.

[tex]x < 5[/tex]

To graph this, you will just add an open circle on 5 and shade every number to the left of it.

Let's simplify step-by-step

8y-3x/4/4 -(-7+5x/3)

Distribute:

=-3/16 x +1/2 y+-5/3 x+7/3

Combine like terms:

=-3/16x+1/2 y +-5/3x+7/3

=(-3/16x+-5/3x)+(1/2y)+(7/3)

=-89/48x +1/2y+7/3

Answer: -89/48x+1/2y+7/3

A.

Step-by-step explanation:

Range of a function is the value that we get when a function is solved.

Say, f(x) = y.

We say this "set of x is domain" whereas "set of y is range".

Suppose,

set A = {1,2} & set B = {1,2,3} & f(x) = y

Let,

f(1) = 1, & f(2) = 2.

What we get is that there is no x for 3.

We say this fact by "set A is domain" & "set B is co domain" & set {1,2} (output) is range.

y=(8x-8)3+7

y=24x-24+7

y=24x-17

AE=BD

A= BD/E

Then,

therefore, A=BE/E (SINCE, D=E)

So, A=B

or, AC= BC (multiplying by C)

Answer:

= 5/29

Step-by-step explanation:

We can use the slope formula to find the slope

m = ( y2-y1)/(x2-x1)

    = ( 8-3)/(13 - -16)

    = ( 8-3)/( 13+16)

   = 5/29

Step-by-step explanation:

Order these numbers from largest at the top, to smallest at the bottom.

1.57x10^-4

4.5x10^3

1.3x10^1

987

We can see that:-

The exponent with highest power is the largest number.

Here, the largest number is

[tex]1.3 \times 10 ^3[/tex]

Next, is [tex]987[/tex]

Smaller than this, next is :-

[tex]1.3 \times 10^1[/tex]

A number with negative power is smaller.

So, last is

[tex]1.57 \times 10^{-4}[/tex]

Answer:

106

Step-by-step explanation:

ruff

123 dogs adoption in january

196 dogs adoption in July

Total adoption for the year = 123 + 196

= 319 adoptions

barks

78 dogs adoption in January

135 adoption in July

Total s like adoption for the year = 78 + 135

= 213 adoptions

Difference in the number of dogs adoption at each shelter that year

= Ruff total adoption for the year - Bark's total adoption for the year

= 319 adoptions - 213 adoptions

= 106

The difference in the number of dogs adoption at each shelter that year is 106

Given:

After driving for 20 minutes, Juan was 62 miles away from his apartment.

After driving for 32 minutes Juan was only 38 miles away.

The time driving and the distance away from his apartment form a linear relationship.

To find:

The independent and dependent variables.

Solution:

If the value of a variable depends on the another, then it is called dependent variables.

If the value of a variable does not depend on the another, then it is called independent variables.

In the given problem, the distance of Juan from his apartment depends on the time he drove. So,

Dependent variable = Distance of Juan from his apartment in miles.

Independent variable = Time he drove

The answer is Dun Dun Duuun 3 {x/4} - 1/2{x/10}

The expression equivalent to 70% of x is,

⇒ 3 (StartFraction x Over 4 EndFraction) minus one-half (StartFraction x Over 10 EndFraction)

⇒ 3 (x/4) - 1/2 (x/10)

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

We have to given that;

The expression is,

⇒ 70% of x

Now, We an simplify the expression as;

⇒ 70% of x

⇒ 70/100 × x

⇒ 70x/100

⇒ 7x/10

By option 1;

⇒ 3 (x/4) - 1/2 (x/10)

⇒ 3x/4 - x/20

⇒ (60x - 4x) / 80

⇒ 56x / 80

⇒ 7x/10

Step-by-step explanation:

Plug in -7 for x and -6 for y into given equation and evaluate.

Answer: Exact Form: d= 2√58

Decimal Form: 15.23154621...

Step-by-step explanation:

Distance formula: d=√(x2-x1)^2 + (y2-y1)^2

d=√(5- -9)^2 + (-4 - 2)^2

Exact Form: d= 2√58

Decimal Form: 15.23154621...

The distance between two points (-9,2) and (5,-4) is 15.23 units.

The distance between two points is defined as the length of the line segment between two places representing their distance. Most significantly, segments that have the same length are referred to as congruent segments and the distance between two places is always positive.

The formula of distance between two points is P(x₁, y₁) and Q(x₂, y₂) is given by: d (P, Q) = √ (x₂ – x₁)² + (y₂ – y₁) ².

We have to determine the distance between (-9,2) and (5,-4)

As per the question, substitute the known values in the formula,

d = √ {(-9 – 5)² + (2 – (-4))²}

d = √ {(-14)² + (6)²}

d = √ {196 + 36}

d = √232

d ≈ 15.23

Thus, the distance between the given two points is 15.23 units.
