Answer:
x = 3
Step-by-step explanation:
It should NOT be "fight of the origin", rather "right of the origin".
Now let's move on to solve the question...
The x-intercept is found by setting the function equal to 0. Thus:
0 = x^3 - 9x
Let's solve this using algebra:
Hence, x = -3 and x = 3
The coordinate that is to the right of the origin is the positive one, so x = 3 is the x-intercept we are looking for.
Answer:
(a) F(x) = 2x^2 - x - 1
Step-by-step explanation:
The quadratic regression function of a graphing calculator does this nicely.
The one attached shows the function to be ...
F(x) = 2x^2 -x -1
__
Additional comments
The supplied point (0, -1) tells you the y-intercept is -1. That means the constant in the function's equation will be -1. Only one answer choice has that.
F(x) = 2x^2 -x -1
__
As always, the first step in problem solving should be to look at the problem, and look at the available solution choices. Understanding these things will generally allow you to throw out answer choices that don't provide a sensible answer to the question. Here, that leaves you with only one answer choice, which is all you need.
Answer: $8.97
Step-by-step explanation:
he bought three jars and lowered the price by 75 cents for each, so multiply $0.75 by three
$0.75 * 3 = $2.25
so henri saved $2.25 in total
we can add that to what he paid to find the original cost
$6.72 + $2.25 = $8.97
so the original price was $8.97 :)
Answer: 8 to 10, 16 to 25, 40 to 50
Step-by-step explanation: If you have trouble wit this in the future just multiply each number by 2,3,4,5,6...
Answer:
Two are actually equivalent, 8:10and 12:15
