Answer:
c
Step-by-step explanation:
The minimum and the x intercept are the same point.
Your answer is the second best answer. The definition of an x intercept is the point on a graph where y = 0. In this case, the graph begins to move in the opposite direction from the direction it was moving.
And so the x intercept just touches the x axis. Good enough. It is still classified as the x intercept because y = 0.
That they both can be different unit o systems
Answer:
Given: x²5x - 10 = 0
On comparing the given equation with ax² + bx + c = 0, we get: a = 1, b = -5 and c = -10
For ax²+bx+c = 0, we know that,
-b ± √b² - 4ac 2a X =
[Quadratic
formula]
5± √(-5)² - 4 × 1 × (-10) ... X = 5± √65 2
2 x 1
5 ± 8.06 2
5 +8.06 5-8.06 2 2
13.06 3.06 2 2
Hence, x = 6.53, or x = -1.53.
We could round both numbers to make estimation easier. So let’s say 82 is 80 and 697 is 700. If we know that 8 x 7 is 56, then 80 x 700 would just be 56,000. This is a great way to find estimates of big numbers.
Answer:
D. f(q) = 2q + 3
Step-by-step explanation:
Choices B and C are eliminated right away because there is no "q" in the definition, just "s". If the function is to be a function of "q", then "q" is expected to appear in the definition.
__
The two variables in the given equation are "s" and "q". If "q" is designated as the independent variable, then the dependent variable is "s". The equation must be solved for "s":
6q = 3s - 9
We observe that the coefficient of "s" is 3, and that all numbers are multiples of 3, so we can divide by 3 to simplify this a bit:
2q = s - 3
Since we want an expression for s alone, we can add 3 to get ...
2q +3 = s
Now, we can write ...
s = f(q) = 2q +3
