Solve for x...................................................................................

Mathematics
1 answer:
mote1985 [20]3 years ago
7 0

Answer:

x = 36°

Step-by-step explanation:

x + 20° + 4x = 200° { exterior angle of a triangle is equal to the sum of two opposite interior angles }

5x = 200° - 20°

5x = 180°

x = 180° / 5

x = 36°

Hope it will help :)

Question 5 (2) x cube - 3x square 9x - 5
kakasveta [241]
Please, post the instructions along with your question, and if possible share the question in symbolic form, not in words.

Do you mean Question #5?  By  (2) x cube, do you mean 2x^3?

I strongly suggest that you use lots of parentheses (   ) to show how your numbers are grouped, and not to use " x " to denote multiplication (use " * " for that, please.    

If only you'll clear this up, I'd be happy to help.

I will assume that your post is   2x^3 - 3(9x-5)^2.

Then 2x^3 - 3(81x - 90x + 25).  Does this have any resemblance to what you wanted me to see in your post?

What equation represents the graphed function
Marina86 [1]

Answer: y=\dfrac{-1}{3}x+3

Step-by-step explanation:

The equation of ab line that passes through two points (a,b) and (c,d) is given by :-

(y-b)=\dfrac{d-c}{b-a}(x-a)

From the given picture , the line is passing through points (0,3) and (3,2).

Then, the equation of the line will be :-

(y-3)=\dfrac{2-3}{3-0}(x-0)

\Rightarrow y-3=\dfrac{-1}{3}x

\Rightarrow y=\dfrac{-1}{3}x+3

Hence, the required equation of the line that represents the graphed function : y=\dfrac{-1}{3}x+3

-x^(2)-12=-87<br><br> Please explain your answer, and how I make the x positive
spayn [35]
Solve for x over the real numbers:
-x^2 - 12 = -87
Add 12 to both sides:
-x^2 = -75
Multiply both sides by -1:
x^2 = 75
Take the square root of both sides:
Answer:  x = 5 sqrt(3) or x = -5 sqrt(3)  both Answers are correct
