The solution to the given inequality [tex]3x \leq -54[/tex] is [tex]x \leq \frac{-54}{3}[/tex] .

Inequality is a fine statement that compares two values, showing if one is lower than, lesser than, or simply not equal to another value. Inequalities are frequently used to represent connections between amounts, similar to the relationship between the height and weight of a person, or the relationship between the speed and time of an object in stir.

We first divide the inequality [tex]3x \leq -54[/tex] by 3 on both sides to obtain:

[tex]x \leq \frac{-54}{3}[/tex] .

Then, we plot the line [tex]x = \frac{-54}{3}[/tex] on the graph. The region left to the line thus obtained is the solution of the given question.

Thus, the line [tex]x \leq \frac{-54}{3}[/tex] is plotted in the graph.

The inverse of the given function is f-1(x)= x²+4.

A function that "undoes" another function in mathematics is known as an inverse. In other words, if f(x) produces y, then y entered into the inverse of f produces x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f-1.

To calculate the inverse of a function:

Consider f(x)=y

And interchange the variables.

So given f(x)= √x-4 becomes

y=√x-4 ⇒ x=√y-4

Now on squaring both sides we get,

x²= y-4

⇒ y = x²+4

Replace y by f-1(x)

So the equation becomes,

f-1(x) = x²+4

He will read 210 pages of the book and it will take Amir 6 days to catch up with Jesse

Day Jesse started reading: Saturday

Number of pages read by Jesse each day: 30 pages

Day Amir started reading: Sunday

Number of pages read by Amir each day: 35 pages

Let x represent the number of days Amir has been reading and y represent the number of pages he has read

Formulating the equation for Amir we get:

y = 35*x

y = 35x

The equation for Jesse will be:

y = 30*(x+1)

y = 30(x+1)

Equating both equations we get:

35x = 30(x+1)

35x = 30x +30

5x = 30

x=6

So, the number of pages read will be 210 and it will take 6 days for Amir to catch up with Jesse

Although a part of your question is missing, you might refer to this full question: Jesse and Amir were assigned the same book to read. Jesse started reading on Saturday, and he is reading 30 pages a day. Amir didn't start until Sunday, but he is reading 35 pages a day.

This is not a function, we know this because the input x = 1 is mapped into two different outputs.

A relation maps elements from one set, the domain, into elements from another set, the range. A relation is only a function if each element of the domain is mapped into only one element of the range.

In this case, we have the relation:

x: 1, -2, 1, -3

y: 2, 1, 3, -2

The input x = 1 is mapped into two different values, y =2 and y = 3.

Answer:

x = 18

Step-by-step explanation:

the angles pictured are supplementary angles.

supplementary angles are angles whose sum equals 180°

ex: <1 + <2 = 180°

[tex]5x - 11 + 6x - 7 = 180[/tex]

[tex]11x - 18 = 180[/tex]

[tex]11x = 198\\x = 18[/tex]

Answer:

[tex]\boxed{\sf{x=18}}[/tex]

Step-by-step explanation:

To find the value of x, you have to use the supplementary angles which is equal to 180°.

Supplementary angles = 180°

5x-11+6x-7=180

Combine like terms.

[tex]\sf{5x+6x-11-7=180}[/tex]

5x+6x=11x

[tex]\sf{11x-11-7=180}[/tex]

Subtract the numbers from left to right.

-11-7=-18

[tex]\sf{11x-18=180}[/tex]

You have to add by 18 from both sides.

11x-18+18=180+18

Solve.

Add the numbers from left to right.

180+18=198

11x=198

Divide by 11 from both sides.

11x/11=198/11

Solve.

198/11=18

Therefore, the final answer is x=18.

If Martin earned $8.75 an hour plus another $18 in tip and Lawrence earned $9.25 an hour and spent $2 on a soda, then the inequality represents the situation is 8.75x+18 < 9.25x-2

The payment of Martin per hour = $8.75

The addition tip he got = $18

The payment of Lawrence per hour = $9.25

The amount he spend for soda = $2

x represents the number of hours worked

Lawrence had more money than Martin

Then the inequality will be

8.75x+18 < 9.25x-2

Hence, if Martin earned $8.75 an hour plus another $18 in tip and Lawrence earned $9.25 an hour and spent $2 on a soda, then the inequality represents the situation is 8.75x+18 < 9.25x-2

Combination is a counting technique where the order of the selected items from a collection does not matter. The formula in finding the number of combinations when ‘r’ items are chosen out of a total of ‘n’ objects.

nCr = n! / [r! (n - r)!]

If there are 2 of 5 options for seat colors, then using the formula, the number of combinations for the seat color is:

Answer:

x = 16.4

Step-by-step explanation:

From the diagram, we can see that the radius of the circle is 19.4 as the line labelled 19.4 goes from the centre to the edge of the circle.

Therefore the length of the line marked in green is also 19.4 units, as it is also a radius of the circle.

Now we can simply use the Pythagorean Theorem to calculate the value of [tex]x[/tex]:

[tex]19.4^2 = x^2 + 10.3^2[/tex]

⇒ [tex]x^2 = 19.4^2 - 10.3^2[/tex]

⇒ [tex]x = \sqrt{19.4^2 - 10.3^2}[/tex]

⇒ [tex]x = \bf 16.4[/tex]

Therefore the length of the indicated segment is 16.4 units.

Answer:

5 minutes and 20 seconds

Step-by-step explanation:

basically your equation is: (rate of filling container) x (time to fill container)

- (minus)

(rate of leaking from container) x (time to fill container)

=

(the size of the container in gallons)

--------------------

step 1 - so t = the time in minutes to fill14 gallon container

step 2 - convert 2 3/4 to quarters so:

2 • 4 = 8 and it’s in quarters so 8/4 then

8/4 + remaining 3/4 = 11/4

step 3 -  so then you fill in the equation:(11/4)•t - (1/8)•t = 14

step 4 - multiply both sides of the equation by 8:

(11/4) = 2.75 • 8 = 22

(1/8) = 0.125 • 8 = 114 • 8 = 112

so the equation is:

22t - t = 112

step 5 - divide both sides of the equation by 22:

22t / 22 = t 

112 / 22 = 5.333

so t = 5.333 

step 6 - convert 

so 5.333 has a repeating decimal of 0.3 which is 1/3. so to convert that to seconds, take 1/3 of  60:

 60 / 3 = 20 

so it takes 5 minutes and 20 seconds to fill the 14 gallon container
