Answer:
, and , .
Step-by-step explanation:
A polynomial is an algebraic function of the form:
(1)
Where:
- i-th Coefficient.
- i-th Power.
- Grade of the polynomial.
- Dependent variable.
Mathematically speaking, polynomials are unbounded functions, and from graphic we notice that polynomial is of order 3 due to the fact that function pass through the x axis three times, where each point is a root of the polynomial.
Then, we may conclude that:
(i)
(ii)
Then, the right answer is: , and , .
Step-by-step explanation:
<u>y</u> - <u>1</u> = <u>-</u><u>3</u>
x - 0 2
2y - 2 = -3x
2y = -3x + 2
Ya know what y’all think ima is a good day to ya ya know ya
Because the slope is negative, you would expect that y decreases and x increases. To check this, you can substitute values for x. At x=0, y=0. Increase x to 1, and y=-3.
Answer:
y=4
Step-by-step explanation:
42/30 = (y+24)/20
Cross multiplying,
30*(y+24) = 42*20
30y + 30*24 = 840
30y + 720 = 840
Subtract 720,
30y + 720 - 720 = 840 - 720
30y = 120
Divide by 30,
y = 120/30 = 4
