Step-by-step explanation:
Answer:
1) D. ![y = -\frac{3}{2}\cdot x^{12} -7\cdot x^{5}+\frac{2}{3}\cdot x -10](https://tex.z-dn.net/?f=y%20%3D%20-%5Cfrac%7B3%7D%7B2%7D%5Ccdot%20x%5E%7B12%7D%20-7%5Ccdot%20x%5E%7B5%7D%2B%5Cfrac%7B2%7D%7B3%7D%5Ccdot%20x%20-10)
2) E. The coefficient of
is -16.
Step-by-step explanation:
1) A polynomial is an algebraic expression of the form
, where
is the grade of the polynomial. In this case, the only equation that satisfies this definition is:
![y = -\frac{3}{2}\cdot x^{12} -7\cdot x^{5}+\frac{2}{3}\cdot x -10](https://tex.z-dn.net/?f=y%20%3D%20-%5Cfrac%7B3%7D%7B2%7D%5Ccdot%20x%5E%7B12%7D%20-7%5Ccdot%20x%5E%7B5%7D%2B%5Cfrac%7B2%7D%7B3%7D%5Ccdot%20x%20-10)
Correct answer: D
2) Let
, we proceed to expand the expression by algebraic means:
![p(x) = (2\cdot x + 1)\cdot (5\cdot x^{3}) -(2\cdot x +1)\cdot (8\cdot x) + 4\cdot (2\cdot x + 1)](https://tex.z-dn.net/?f=p%28x%29%20%3D%20%282%5Ccdot%20x%20%2B%201%29%5Ccdot%20%285%5Ccdot%20x%5E%7B3%7D%29%20-%282%5Ccdot%20x%20%2B1%29%5Ccdot%20%288%5Ccdot%20x%29%20%2B%204%5Ccdot%20%282%5Ccdot%20x%20%2B%201%29)
![p(x) = 10\cdot x^{4}+5\cdot x^{3}-16\cdot x^{2}+4](https://tex.z-dn.net/?f=p%28x%29%20%3D%2010%5Ccdot%20x%5E%7B4%7D%2B5%5Ccdot%20x%5E%7B3%7D-16%5Ccdot%20x%5E%7B2%7D%2B4)
We see that coefficients for
and
are -16 and 0, respectively. Hence, the incorrect answer is E.
Slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept. This makes the equation of our line y = 2x+0 or y = 2x.
Answer:
Step-by-step explanation:
If the number is 6 then
Product of 8 x 6 = 48
48 - 10 = 38
So the number is 6
