Find y when x=9 if y varies directly as the square of x, and y=100 when x=5.
sukhopar [10]
If y varies directly as the square of x, that means that y=k*x^2. Plugging y=100 and x=5 into it, we get 100=k*5^2=k*25. Dividing by both sides, we get k=100/25=4. Going back to the original equation, we now know that y=4*x^2. Plugging 9=x in, we get 4*9^2=4*81=324=y

Determine whether each ordered pair is a solution to the inequality x+y<−1.
polet [3.4K]

Answer:

Choice A.  (10, -1)
Choice B.  (-8, 9)
Choice D.  (6, -3)

Step-by-step explanation:

If we plug the coordinates of point A into the inequality, then we get,
x+y > -2

10 + (-1) > -2
9 > -2
That last inequality is a true statement since 9 is to the right of -2 on the number line. That means (10,-1) is a solution. Choice A is one of the answers.
Choices B and D are also answers
for similar reasons.
Something like choice C is not a solution because
x+y > -2
-1+(-9) > -2
-10 > -2
Which is false.
You should find that choice E is false as well.

If you graphed the inequality and all of the points mentioned (see below), then you can visually confirm the answers. Notice how points A, B and D are in the blue shaded region which is the solution set.
The point E on the boundary does not count as a solution. This is due to the lack of "or equal to" portion of the inequality sign. That visually shows point E is not a solution. Point C isn't a solution either as it's nowhere near the blue shaded region.

Graph each absolute value function. State the domain, range, and y-intercept.
SVEN [57.7K]

Answer:

The domain is  (-\infty,\infty) and its range is [3,\infty).

The y-intercept is (0,3).

Step-by-step explanation:

Consider the parent function y=|x|. Its domain is x\in (-\infty,\infty) and its range is y\in [0,\infty).

The graph of the function y=|x|+3 is obtained from the graph of parent function by translation 3 units up (see diagram). This translation doesn't change the  domain and will change the range of the function, thus the domain is  (-\infty,\infty) and its range is [3,\infty).

To find th y-intercept you have to find y at x=0:

y=|0|+3=3.

Hence, the y-intercept is (0,3).
