A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

Two sides of right triangle are,

⇒ 5 cm, 12 cm

Since, The triangle is a right triangle.

So, We can apply the Pythagoras theorem as;

Let the measure of missing side = x

⇒ x² = 5² + 12²

⇒ x² = 25 + 144

⇒ x² = 169

⇒ x = √169

Hey there!☺

[tex]Answer:\boxed{x=2}[/tex]

[tex]Explanation:[/tex]

[tex]3(-x+4)=7x-8[/tex]

Let's start by simplifying both sides. First, we distribute.

[tex](3)(-x)+(3)(4)=7x+-8[/tex]

[tex]-3x+12=7x+-8[/tex]

[tex]-3x+12=7x-8[/tex]

Now let's subtract 7x from both sides.

[tex]-3x+12-7x=7x-8-7x\\-10x+12=-8[/tex]

Now we will subtract 12 from both sides.

[tex]-10x+12-12=-8-12\\-10x=-20[/tex]

In our last/final step, we will divide both sides by -10.

[tex]\frac{-10x}{-10}=\frac{-20}{-10}[/tex]

Now simplify -20/-10.

Given :

Joseph tweets 13 times a day.

To Find :

An algebraic expression to describe the number of posts after any given number of days.

Solution :

Let, number of tweets after x days are y.

Let, the relationship is , y = mx + c.

For, x = 1

13 = m +c     ...... 1)

x = 2

26 = 2m + c   .......2)

So, m = 13 and c = 0.

Therefore, algebraic expression to describe the number of posts after any given number of days is y = 13x.

Hence, this is the required solution.

Find the inverse of the following function g(x) = 2x+10/4

Answers

Answer:

Step-by-step explanation:

To find the inverse of the function you need to swap x and y

g(x)=y so therefore if you switch x and y, you get

x= 2y+ 10/4

Next, you need to get all of the values on the y side over to the x side. To do this you need to subtract 10/4 from the y side of the equation.

x-10/4=2y+10/4-10/4

The end product of this should be... (This is not your answer)

x-10/4=2y

Now you need to get rid of the 2 on the y side. To do this you need to divide both sides of the equation by 2

2/x-10/4=2y/2

So your answer is...

x-10/4 over 2 = y

OR

2/x + 5/4 = y
