Answer:

yes, it is B

Step-by-step explanation:

every input value of x has an unique result value y.

there are no 2 values for x that produce the same result value y.

and there are no multiple result values possible for a subject x value.

bottom line, yes, it is a function, and a 1:1 function at that.

X-3y=7 and 2x-6y=12 solving by elimination

Ber [7]

x-3y=7 2x-6y=12

You can multiply -2 in the first equation like this.

x+6y=7

2x-6y=12

Now you can eliminate 6y and -6y so cross them out and do x-2 which is -1 and 7-12 which is -5 -1/-5 would be .2

Radius= 4cm. find the area and diameter of the circle

Bezzdna [24]

<h3>given:</h3>

radius= 4 cm

the area and the diameter of the circle.

<h3>solution:</h3><h3>diameter:</h3>

$d = 2r$

$d = 2 \times 4$

$d = 8 \: cm$

therefore, the diameter of the circle is 8 centimeters.

$a = \pi {r}^{2}$

$a = \pi \times {4}^{2}$

$a = 50.26548 \: {cm}^{2}$

$a = 50.27 \: {cm}^{2}$

hence, the area of the circle is 50.27 square centimeters.
