The answer would be A.
Deena is correct because that is not a rational number
Irrational numbers are numbers that are crazy and don’t have an end to them. Example would be pi because it goes on forever and ever. But it you have something that is straight to the point like 2.3 or -4/7 these are RATIONAL because they have an end and are “contained”, this goes for numbers that are repeating too.. if you have like 2.3repeating, then this is also rational because you know what the number is, and it is consistent.
I hope this helps explain rational and irrational a little better :)

What is the distance between (5, 7) and (-2,-2)? Round to the nearest tenth, if necessary.

lakkis [162]

Answer:

The distance between (5, 7) and (-2,-2) is 11.4 units.

Step-by-step explanation:

We are given the following in the question:

Points:

(5, 7) and (-2,-2)

We have to find the distance between the two points.

Distance formula:

$d =\sqrt{(y_2-y_1)^2+(x_2-x_1)^2)}$

Putting values, we get,

$(x_1,y_1) = (5,7)\\(x_2,y_2) = (-2,-2)\\\\d = \sqrt{(-2-7)^2 + (-2-5)^2} = \sqrt{130} \approx 11.4\text{ units}$

Thus, the distance between (5, 7) and (-2,-2) is 11.4 units.

4. If f(x) = 2x + 4y and g(x) = 2x2 -3x + 6y, find g(x) – f(x)

laiz [17]

Answer:

B. 2x^2 -5x +2y

Step-by-step explanation:

Substitute the given expressions and collect terms.

g(x) -f(x)

= (2x^2 -3x +6y) -(2x +4y)

= 2x^2 -3x +6y -2x -4y

= 2x^2 -5x +2y . . . . . . . . . . matches choice B
