Select the coordinates of two points that are on the line x=5

Dmitry_Shevchenko [17]

You can choose the coordinates of any two points on the vertical line where x=5.
So for the coordinates, you need a y value for both. Since the points have to be on that line, you already know that the x value has to be 5.

Which function is equivalent to f(x)=1/4(x-2)^2+3?

QveST [7]

Answer: f(6) = (6)2 + 1 = 36 + 1 = 37

If we wanted to find and expression for f(g(x)) we could plug in g(x), which is "x - 4" into the function f(x) wherever we see an "x". So:

f(x) = x2 + 1

f(g(x)) = (x - 4)2 + 1 because g(x) is "x - 4"

Domain and range of the inequality y<√x+3 +1

Margaret [11]

The domain of the given inequality is y>1.

<h3>What is Inequality?</h3>

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Here, given inequality:

y < $\sqrt{x+3}+1$

Related equation:

y = $\sqrt{x+3}+1$

The equation defined as,

x+3 > 0

x > -3

In the given inequality, the sign of inequality is <, it means the points on the boundary line are not included in the solution set. Thus, -3 is not included in the domain.

So, the domain of the given inequality is x>-3.

We know that,

$\sqrt{x+3} \geq 0$

adding 1 on both sides, we get

$\sqrt{x+3} + 1 \geq 1$

y ≥ 1

The points on the boundary line are not included in the solution set. Thus, 1 is not included in the range.

Thus, the domain of the given inequality is y>1.

The ratio of boys to girls in a class is 5:4. There are 36 students in the class. How many students are girls?

maksim [4K]

Answer:

16 girls

Step-by-step explanation:

If the ratio Is b:g, then we can assume the majoraty are boys.

If we look at the factors for these numbers, it goes like this: 5, 10, 15, 20, 25 for 4, we get 4, 8, 12, 16, 20, 24. If you look at the fourth factor, 20, and 16, then you can see that they add up to 36.
