line one should have a y-intercept at (0,2).
Step-by-step explanation:
Answer:
x = 52, y = 26
Step-by-step explanation:
x - 2y = 0
40 - y = 14
(40 - 40) - y = 14 - 40
- y = -26
y = 26
x - 2(26) = 0
x - 52 = 0
x (- 52 + 52) = 0 + 52
x = 52
He made $600 profit on it. 3000 * .20 = 600
Answer:
k = 3
Step-by-step explanation:
If p-1 is a factor of p⁴+p²+p-k, then we can express the polynomial in form
p⁴+p²+p-k = (p-1) * (ap³ + bp² + cp + d)
where a,b,c,d are constants. The important thing is that we can subst in p = 1 to make the polynomial zero. We can do this for original polynomial. WE must have to equal to 0 when we use p = 1 substitution...
1⁴+1²+1-k = 0
3 - k = 0
k = 3
