Which function is the inverse of f(x) = -5x—4

The marble that is heavier based on the ratio is purple marble.

Ratio demonstrates how many times one number can fit into another number. Ratios contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data point (A) to another data point (B).

This indicates that you're dividing information A by B. For instance, the ratio will be 5/10 if A is 5 and B is 10.

Red balloons float purple marbles at a ratio of 12: 4. This will be:

= 12/4

= 3

Red balloons float green marbles at a ratio of 15: 6. This will be:

= 15/6

= 2.5

In this case, the purple marble is heavier as 3 is more than 2.5.

The value of the sets are A ∩ ∅  = ∅ and A' ∪ U  = {f, g, h, p, q, r}.

Given: U = {f, g, h, p, q, r} and A = {g, p, r}

We are to find: (a)A ∩ ∅  and (b) A' ∪ U

(a) A ∩ ∅  

The symbol ∩ means intersection. This tells us what sets have in common. Also, the symbol ∅ means an empty set or null. That is a set that does not have any element

The intersection of a set with the empty set is the null set. Thus:

A ∩ ∅  = ∅

(b) A' ∪ U

The set U is called the universal set

A' means elements not in set A but in set U

The symbol ∪ means union, A' ∪ U will give a list of elements in A' and U combined without repetition. Thus:

A' ∪ U = {f, h, q} ∪  {f, g, h, p, q, r}  = {f, g, h, p, q, r}

Therefore, A ∩ ∅  = ∅ and A' ∪ U  = {f, g, h, p, q, r}. They should be entered into the boxes accordingly

Answer:

The bottom right

Step-by-step explanation:

A relation is just a set of ordered pairs.  A function is a special relation.  In a function every input (x) has only one output (y).  

You can use the vertical line test.  If you took your pencil and vertical passed over the graph left to right. If there is any point that more than one point would be under the pencil, the relation is not a function.

After solving the value of x is -1/6.

Given:

[tex]25^3^x^+^2[/tex] = 125

[tex]5^{2(3x+2)}[/tex] = [tex]5^3[/tex]

2(3x+2) = 3

6x + 4 = 3

6x = 3-4

6x = -1

divide by 6 on both sides

6x/6 = -1/6

x = -1/6.

Answer A ; 4934 is the P-intercept. which indicates that 4934 people called Minnesota home in 2000.

Answer B ;  T-intercept is -4934/37, or approximately -133. This indicates that Minnesota had a population of 2000–133 in 1867.

Answer A : P=37t+4934 can be used to represent Minnesota's population in thousands over the t years after 2000.

P-intercept is the P value at time t=0.

P=37*0+4934\sP=0+4934\sP=4934

So, 4934 is the P-intercept. which indicates that 4934 people called Minnesota home in 2000.

Answer (B) : The term "t-intercept" refers to the value of the function t when P=0 0=37t+4934 -4934=37t divide by 37 -4934/37=t -133.351351351 = t

Hence T-intercept is -4934/37, or approximately -133. This indicates that Minnesota had a population of 2000–133 in 1867.

P=37t+4934 P-intercept means the value of P at t=0 P=37*0+4934 P=0+4934 P=4934

Given that Minnesota's population in thousands, t years since 2000, it can be expressed by the equation:

So, 4934 is the P-intercept. which indicates that 4934 people called Minnesota home in 2000.

Using the given information, we can write the compound inequality for the variable n:

45 ≤ n ≤ 120

Here we know that Liz spends at least 45 minutes and no more than 120 minutes on her phone.

So if we define the variable n as:

n = number of minutes that Liz spends on her phone.

We know that n must be larger than or equal to 45, so we can write the first inequality:

45 ≤ n

And we also know that it must be smaller than or equal to 120, then the other inequality is:

n ≤ 120

Combining the two we can write the compound inequality:

45 ≤ n ≤ 120

Answer: y= (2/3)x - 2

Step-by-step explanation:

The biggest way to remember equations like these is to know rise over run which means however many times it goes up until it intersects with both x and Y will be on the top of the fraction and however many times it goes to the right until it intersects with both x and y will be on the bottom of the fraction. So since it hits (0, -2) then intersects at (3,0) it will be 2/3x and the Y is where X equals zero so it would be -2. Hope that helps!

Step-by-step explanation:

Step 1:

Choose two points on the graph, (x1, y1) and (x2, y2), to find the slope.

Find the ratio between change in y-values and change in x-values.

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

Points I picked:

(x1, y1) = (0, -2)

(x2, y2) = (3, 0)

Then,

m = (0 - (-2)) / (3 - 0)

m = 2/3

Step 2 :

Find the y-intercept from the graph. That is the point at which the line intersects the y-axis.  

The y-intercept is -2.

b  =  -2

Step 3 :

Use the slope (m) and y-intercept (b) to write the equation in slope-intercept form:

y = mx + b

Substitute m = 2/3 and b = -2

y  =  2/3 x - 2

What is Function?

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.

What is domain?

The domain of a function is the set of values that we are allowed to plug into our function.

What is range?

The collection of potential output values for a function is known as its range. For instance, the range is the non-negative real numbers for the function fn(x)=x2 on the domain of all real numbers (x ∈ R), which may be represented as fn(x)≥0 (or [0,∞] using interval notation).

Given:

Domain: {-5, -3, 0, 3, 11)

Range: {4, 0, 2}

If the input of function is a and output is b then it is defined by (a, b).

A ballast resistor is utilized inside the ignition system of automobile engines or balloons. it acts as a resistor for the ignition ballast.

Between the main source of both the ignition coil & the coil stud, there's an ignition ballast resistor. It lowers the ignition coil's risk of failure.

An ignition ballast resistance assists in lowering the coil voltage & coil current when the generator revs the engine.

Minimal current consequently results in a low-temperature increase. Additionally, the ignition coil lives a long time as a result.

However, an ignition system requires a greater voltage that is also the same as the power source's voltage. Therefore, a resistor for the ignition ballast is connected to the jumper wire. The jumper wire additionally supplies the ignition with the necessary voltage when starting the engine.
