Need help! I think this is pretty easy but I'm missing something

Step-by-step explanation:

Hey there!

f(x) = 7/x

~ Simply keep the "7" in the place where "x" is there.

[tex]f(7) = \frac{7}{7} [/tex]

Therefore, X= 1.

Hope it helps....

Answer:

After evaluating the function [tex]f(x)=\frac{x}{7}[/tex] by putting x = 7, we get f(7)= 1

Step-by-step explanation:

We need to evaluate the function [tex]f(x)=\frac{x}{7}[/tex] and find f(7)

For finding f(7) we will put x = 7 in the given function [tex]f(x)=\frac{x}{7}[/tex]

So, putting x= 7 and finding f(7)

[tex]f(x)=\frac{x}{7}\\Put\:x=7\\f(7)=\frac{7}{7}\\f(7)=1[/tex]

So, after evaluating the function [tex]f(x)=\frac{x}{7}[/tex] by putting x = 7, we get f(7)= 1

Answer:

C) Explain how the equations are equal and just prove it with a check or just plug in a number like for ex: x=1 and I checked with both and it equals out.

d) Use inverse operations (or you can say do the order of operations in reverse and then use invers operations), provide an example if you think what you said doesn’t make sense, like for

Ex: 2x-1=43+5x

     2x=44+5x (add the -1)

     -3x=44  (subtract 5x to both sides)

       X=44/-3 (isolate the variable by dividing 3 on both sides)

An example is always better

E) Just use inverse operations and solve it like what you would normally do

Y = 3.25

Step-by-step explanation:

Hope this helps. Pls give brainliest.

Answer:

x = 0

y = 3.25

Step-by-step explanation:

You can do elimination. Multiply (9x + 4y = 13) by 2

4x - 8y = -26

18x + 8y = 26

22x = 0

x = 0

4(0) - 8y = -26

-8y = -26

y = 3.25

Step-by-step explanation:

The length of the octagon is 6cm, the area is given by 3h and the height is 7.23 cm.

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.

In a triangle, the sum of all three angles is 180°

Triangle is a very common figure to deal with our daily life for example in our daily life to measure the height of any tower then there is a huge application of the right angle triangle.

Given the octagon with a perimeter of 48 cm

Let's say the length of each side is a

Perimeter = 8a

8a = 48

a = 6cm

Now,

The area of the triangle is given by

A = 1/2  × Base × Height

A = 1/2  × 6 × h

A = 3h

Now

A = 3h and the area is 21.7 cm²

So,

h = 21.7/3 = 7.23 cm

Hence "The length of the octagon is 6cm, the area is given by 3h and the height is 7.23 cm".

The sum is -14

Step-by-step explanation:

To solve this problem , first you should look at key words. The key word is SUM. What does sum mean? Sum means ADDING or addition. So,  you know what operation to use and then ADD the values of the 3 cards. -12+3+-5 = -14.

So the sum of the values are Of LuAnn's three cards is -14.   Hope it helps!

Answer:

The nth term will be:

Step-by-step explanation:

Given the sequence

-5, -15, -25, ...

An arithmetic sequence has a constant difference 'd' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

computing the differences of all the adjacent terms

[tex]-15-\left(-5\right)=-10,\:\quad \:-25-\left(-15\right)=-10[/tex]

The difference between all the adjacent terms is the same and equal to

[tex]d=-10[/tex]

The first element of the sequence is:

[tex]a_1=-5[/tex]

Thus, the nth term will be:

[tex]a_n=a_1+\left(n-1\right)d[/tex]

substituting the values [tex]d=-10[/tex]; [tex]a_1=-5[/tex]

[tex]a_n=-10\left(n-1\right)-5[/tex]

[tex]a_n=-10n+5[/tex]

Plug in n = 93 to determine the nth term

[tex]a_{93}=-10\left(93\right)+5[/tex]

[tex]a_{93}=-930+5[/tex]

[tex]a_{93}=-925[/tex]

Therefore, the nth term will be:

Answer:

$159.1

Step-by-step explanation:

Given that:

Original price of surfboard = $199

Reduction of price done = 10%

Then a coupon is used by a customer for $20 off.

To find:

How many dollars were paid by the customer?

Solution:

First of all, let us find the price after the reduction of 10% from the original price.

10% of $199 = [tex]\frac{10}{100}\times 199 = \$19.9[/tex]

This price is reduced from the original price.

Price after reduction = $199 - $19.9 = $179.1

Now, again there is coupon of $20.

Therefore, final price that the customer had to pay = $179.1 - $20 = $159.1
