Answer:

x = 15

Step-by-step explanation:

<u><em>Using Pythagorean Theorem</em></u>

=> c^2 = a^2+b^2

<u><em>Where c= x, a = 12, b = 9</em></u>

=> x^2 = (12)^2+(9)^2

=> x^2 = 144+81

=> x^2 = 225

Taking sqrt on both sides

=> x = 15

Answer:

\large\boxed{3.\ \dfrac{1}{625t^{12}}}

Step-by-step explanation:

\text{Use}\\\\(ab)^n=a^nb^n\\\\(a^n)^m=a^{nm}\\\\a^{-n}=\dfrac{1}{a^n}\\---------------\\\\(5t^3)^{-4}=\dfrac{1}{(5t^3)^4}=\dfrac{1}{5^4(t^3)^4}=\dfrac{1}{625t^{(3)(4)}}=\dfrac{1}{625t^{12}}

Maximize x and y. P=3x +2y
Natalka [10]

P = 3x + 2y

There is an accompanying graph in this problem. In the graph, there are 4 points to consider. I'll just assign letters on each point.

Point O is found in x = 0 ; y = 0 or (0,0)

Point A is found in x = 8 ; y = 0 or (8,0)

Point B is found in x = 6 ; y = 5 or (6,5)

Point C is found in x = 0 ; y = 8 or (0,8)

We will substitute x and y in the equation by its values per point.

Point A = 3(8) + 2(0) = 24 + 0 = 24

Point B = 3(6) + 2(5) = 18 + 10 = 28

Point C = 3(0) + 2(8) = 0 + 16 = 16 

The maximum value of the function P = 3x+2y is 28 and its minimum value is 16.

The sum of twice a number is at most 15. Write and solve. Give 3 possible whole number solutions.
Sveta_85 [38]

5

4

3

5 + 10 = 15

4 + 8 = 12

3 + 6 = 9

These are at most 15 bust not over 15

6 and above font work because they result in a number above 15

and 2 and below don't work because it is noticeably not close by observation.

Someone help me please
AlladinOne [14]
To find the equation of a line, you need to find the slope and y-intercept by using the slope formula and point slope formula. 

First, let's find the slope. 11 + 5/9 - 1 = 16/8 = 2. Therefore, the slope is 2.

Then, plug it into the point slope formula. 
y + 5 = 2(x - 1). 
Distribute: y + 5 = 2x - 2

Subtract 5 on both sides: y = 2x - 7. 

Your final equation, that you need to plug into your answer, is y = 2x - 7.

Hope this helps!! If you need further assistance, message me or comment under this post!
