Which is a zero of the function f(x) = 2x - 10?

Answers

$f(x)=2x-10\n\na\ zero\ if\ 2x-10=0\n\n2x=10\ \ \ /:2\n\nx=5\n\nAnswer:The\ zero\ is\ x=5.$

Watch carefully:

A 'zero' of the function is a value of 'x' that makes the function zero.

2x - 10 = 0

Add 10 to each side:

2x = 10

Divide each side by 2 :

x = 5

f(5) = 0

If the ones digit of a number greater than 1 is 0,what factor or factors must that number have

Answers

If the units digit is zero, then you have an even number ...
' 2 ' must be one of its factors.

It must also have two or more places ... it's greater than 9.
If it had only one place, and its units digit were zero, then
the whole thing would be zero.

Since it has two or more places, 5 and 10 are also factors.

The equation of circle having a diameter with endpoints (-2, 1) and (6, 7) is(x - 4)² + (y - 3)² = 25
(x - 2)² + (y - 4)² = 25
(x - 2)² + (y - 4)² = 100

Answers

The center of the circle is the midpoint of the diameter.

The 'x' coordinate of the midpoint is (1/2) (6 - 2) = 2
The 'y' coordinate of the midpoint is (1/2) (7 + 1) = 4
The center of the circle is the point (2, 4) .

The length of the diameter of the circle is the distance
between the endpoints of the diameter.

The distance between (-2, 1) and (6, 7) is

√ (8² + 6²)

   = √ (64 + 36)

   = √ 100 = 10 .

The radius of the circle is 1/2 of 10 = 5 .

Now, the equation of any circle is

(x - [x of the center])² + (y - [y of the center])² = (radius)² .

and we have all the numbers now.

(x - 2)² + (y - 4)² = (5)² .

I'm very happy to see that this equation is actually
one of the choices !   I'll bet you are too.

Answer:

$(x-2)^(2)+(y-4)^(2)=25$
