X=8
To find the X-intercept/zero, substitute Y=0
0= -3/2+12
Then Just solve for X
Graphing
rise/run
0.7x - 2 < 5.5
0.7x < 5.5 +2
0.7x < 7.5 Dividing both sides by 0.7
x < 7.5/0.7
x < 10.71.
That's it.
-t(5t - 7) = -5
-1 -1
t(5t - 7) = 5
t(5t) - t(7) = 5
5t² - 7t = 5
5t² - 7t - 5 = 0
t = -(-7) ± √(-7)² - 4(5)(-5)
2(5)
t = 7 ± √49 - 4(-25)
10
t = 7 ± √49 + 100
10
t = 7 ± √149
10
t = 0.7 ± 0.1√149
Answer:
![=5x^{2} +2x-4-(2x^{2} +6x-6)\\=5x^{2} +2x-4-2x^{2} -6x+6\\=5x^{2} -2x^{2} +2x-6x-4+6\\=3x^{2} -4x+2](https://tex.z-dn.net/?f=%3D5x%5E%7B2%7D%20%2B2x-4-%282x%5E%7B2%7D%20%2B6x-6%29%5C%5C%3D5x%5E%7B2%7D%20%2B2x-4-2x%5E%7B2%7D%20-6x%2B6%5C%5C%3D5x%5E%7B2%7D%20-2x%5E%7B2%7D%20%2B2x-6x-4%2B6%5C%5C%3D3x%5E%7B2%7D%20-4x%2B2)
Step-by-step explanation:
Hence,5x²+2x-4 and 2x²+6x-6 are the two polynomials.
To create them:
Let,5x²+2x-4 be the first polynomial and x be the another
Now, we have,
→5x²+2x-4-x=3x²-4x+2
→5x²+2x-4-(3x²-4x+2)=x
→5x²+2x-4-3x²+4x-2=x
→x=3x²-4x+2
