Answer:
(4,-2)
Step-by-step explanation:
11.9 about because I did sin(32°)over y = sin90° over 14 and I got around 7.4 and then I did the Pythagorean theorem so I got around 11.9
Answer:
It says that for me too, there must be a problem with their system.
Try asking the specific problem you are having, so if someone had that specific problem before, they can walk you through it! :)
Hey there!
In order to multiply these polynomials together, you will take both terms of the first polynomial and multiply them by each term in the second polynomial. You can then combine any like terms to get your final answer.
(2x² – 5x)(4x² – 12x + 10)
2x² × 4x² = 8x⁴
2x² × –12x = –24x³
2x² × 10 = 20x²
–5x × 4x² = –20x³
–5x × –12x = 60x²
–5x × 10 = –50x
Write all of these terms together. You can rearrange the similar ones to be next to each other.
8x⁴ – 24x³ – 20x³ + 20x² + 60x² – 50x
Just add or subtract the terms to simplify, if they can be.
8x⁴ – 44x³ + 80x² – 50x
(8x⁴ – 44x³ + 80x² – 50x) will be your final answer.
Hope this helped you out! :-)
The solution of given system of linear equation is:
x=3 and y=10
Step-by-step explanation:
Given equations are:
-8x+5y=26 Eqn 1
9x-3y=-3 Eqn 2
Multiplying equation 1 by 9
-72x+45y=234 Eqn 3
Multiplying Equation 2 by 8
72x-24y=-24 Eqn 4
Adding Eqn 3 and 4
Dividing both sides by 21
Putting y=10 in equation 1
Subtracting 50 from both sides
Dividing both sides by -8
Hence the solution of given system of linear equation is:
x=3 and y=10
