Answer:

(B) Is the answer here

Step-by-step explanation:

Well a function’s domain can’t repeat no matter what.

Domain is X.

So the first one doesnt work since it repeats to every single digit that exists.

The second one works becuase the domain aren’t repeated and the range being repeated (or known as y) is but that deosn’t matter.

Answer:

B

Step-by-step explanation:

Hello There!

In order for the relations to be a function the x values may not repeat

For answer choice A the x value -2 repeats multiply times therefore the relation is not a function

For answer choice B each x value has a different y value so this might be our answer but just to be safe lets look at the other answer choices

For answer choice C the x values -3 and 2 repeat therefore it is not a function

For answer choice D the x value 2 repeats therefore the relation is not a function

So we can conclude that the correct answer is B

A set of equations is shown above. Which method eliminates one of the variables? A) Multiply equation A by -1/3 and add the resu
Paraphin [41]

Answer:


Step-by-step explanation:

Multiplying Equation A by (1/3) and adding the result to Equation B will do the trick.  Let's actually solve the problem!

Equation A:  (5/3)x + 3y = 12

Equation B:    4x     -  3y = 8

                    ---------------------------

                     (5/3 + 12/3)x = 15        Note how this has eliminated the variable

                            (17/3)x = 15           y.

                                   x = (3/17)(15)

A circle has a radius of 9 cm and a sector of the circle has an arc length of 9. 7cm
frutty [35]

Answer:

S = R θ      where θ is in radians

If θ  = 2 pi then S = 2 pi R       the circumference of the circle

θ = S / R = 9.7 / 9 = 1.08 rad

Since 1 rad = 360 / (2 pi) = 57.3 deg

the angle included = 1.08 rad * 57.3 deg/rad = 61.9 deg
