Answer:
Step-by-step explanation:
-5y = -x + 15
5y = x - 15
y = 1/5x - 3
perp. -5
y - 5 = -5(x + 2)
y - 5 = -5x - 10
y = -5x - 5
Answer:
Mean: 14
Step-by-step explanation:
(44+63-17+28-30-24+19+51-8)/9 = 126/9
= 14
Pythagoras: A^2 + B^2 = C^2 where c is the side opposite the hypotenuse (opposite the right angle) and B and C are the other sides. Trigonometry: SOH CAH TOA where you can use their formula where sin = opposite/ hypotenuse Cos= adjacent/ hypotenuse Tan= opposite/ adjacent
Answer:
Step-by-step explanation:
You need to use distributive property and multiply each term of the binomial "3x+7" (that is 3x, and 7) by each term of the trinomial "
" taking care of their appropriate signs, and then combine like terms until there is no more than one term for each power of "x". It is also customary to order the final terms in descending order of power of "x".
Let's start by multiplying as indicated above:
![(2x^2+5x-3)*(3x+7)=\\=2x^2\,*\,3x+2x^2\,*\,7\,+5x*3x+5x*7-3*3x-3*7=\\=6x^3+14x^2+15x^2+35x-9x-21=\\=6x^3+[14x^2+15x^2]+[35x-9x]-21=\\=6x^3+29x^2+26x-21](https://tex.z-dn.net/?f=%282x%5E2%2B5x-3%29%2A%283x%2B7%29%3D%5C%5C%3D2x%5E2%5C%2C%2A%5C%2C3x%2B2x%5E2%5C%2C%2A%5C%2C7%5C%2C%2B5x%2A3x%2B5x%2A7-3%2A3x-3%2A7%3D%5C%5C%3D6x%5E3%2B14x%5E2%2B15x%5E2%2B35x-9x-21%3D%5C%5C%3D6x%5E3%2B%5B14x%5E2%2B15x%5E2%5D%2B%5B35x-9x%5D-21%3D%5C%5C%3D6x%5E3%2B29x%5E2%2B26x-21)
