Answer:

rational

Step-by-step explanation:

In mathematics, a rational number is a number that can be expressed as the quotient or fraction pq of two integers, a numerator p and a non-zero denominator q.

Now √9=3=31=62=93 and so on. Where both numerator and denominator are positive integers.

So, we can say that 1/√9 is a rational number.

The table below represents a function. Which of the following equations could be its function rule?

worty [1.4K]

Answer:

$y=2x-2$ is the required equation.

Therefore, the second option is true.

Step-by-step explanation:

We know that the slope-intercept form of the line equation of a linear function is given by

$y=mx+b$

where m is the slope and b is the y-intercept

Taking two points (0, -2) and (1, 0) from the table to determine the slope using the formula

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(0,\:-2\right),\:\left(x_2,\:y_2\right)=\left(1,\:0\right)$

$m=\frac{0-\left(-2\right)}{1-0}$

$m=2$

substituting the point (0, -2) and the slope m=2 in the slope-intercept form to determine the y-intercept i.e. 'b'.

$y=mx+b$

$-2 = 2(0)+b$

$-2=0+b$

$b=-2$

Now, substituting the values of m=2 and b=-2 in the slope-intercept form to determine the equation of a linear function

$y=mx+b$

$y=2x+(-2)$

$y=2x-2$

Thus, $y=2x-2$ is the required equation.

Therefore, the second option is true.

ABCDEF is a regular hexagon. What is the most

Rzqust [24]

If you start with all the sides of the hexagon being congruent, you can then figure out angle measures, then you can conclude that all the sides of polygon GBHE are congruent, so it is a rhombus.
Each angle at vertices H and G measures 120 deg.
Each angle at vertices E and B measures 60 deg.

A football lost 9 yards during a play. The team had a combined gain or lose of 0 yards

evablogger [386]

<span>In this instance, it would seem that if they gained 9 yards and then, lost 9 yards, it would 0 the gain and loss of yards out. This would explain why the team didn't have a gain or a loss.</span>

The first term in a sequence is 3. the term to term rule is add 5. is 97 at term in the sequence? give a reason why.

Harlamova29_29 [7]

Answer: No it’s not.

Step-by-step explanation: So if to find the next number, you add five, then all of the numbers in the sequence will either end with 8 or 3. (5+3 or 0+3). Therefore 97 is not a term in the sequence.
