If <span>y = -x + 7, and (-1,y) is on the graph, then the following is true: y=-(-1) + 7, or y=8.
Thus, y = a0 = 8.</span>
Answer:
2000
Step-by-step explanation:
Just do 6 x 0.2 to reverse the division
So the answer is 1.2
I think
Answer 200 to 520 and 300 to 580.
Step-by-step explanation:
Each one increases by 60.
Answer:
(a) yes
(b) no; see below
Step-by-step explanation:
(a) Integer roots of the quartic will be integer divisors of 6. One of the divisors of 6 is 3, so 3 is a possible root.
(b) In order for 3 to be a double root, it would have to be a double factor of 6. The only integer factors of 6 are 1, 2, 3, 6. (3² = 9 is not one.)
___
The quartic can be written as ...
k(x -a)(x -b)(x -c)(x -d) . . . . . where a, b, c, d, k are integers
The constant term will be kabcd, of which each of the roots is a factor. If the constant is 6 and one root is d=3, then we must have
kabcd = 3kabc = 6
kabc = 6/3 = 2
Among these four integer factors, there must be an even number of minus signs, and one that has the value ±2. Another root whose value is 3 will not satisfy the requirements.
